空气质量传感器TGS2600在空气质量监测中的应用
空气质量传感器TGS2600在空气质量监测中的应用引言近年来，空气质量监测越来越受到人们的重视，国内外的众多企业与研究机构在气体传感器研发领域取得了长足进步，目前气体传感器正向集成化、智能化、多参数检测的方向迅速发展。
日本FIGARO公司开发生产的系列半导体气体传感器代表了目前气体传感器领域最新的水平，为研究开发空气质量监测系统创造了有利条件，提供了一条简单而实用的途径。
1 半导体气敏传感器及其特性半导体气敏传感器是利用待测气体与半导体（主要是金属氧化物）表面接触时，产生的电导率等物性变化来检测气体。
半导体气敏器件被加热到稳定状态下，当气体接触器件表面而被吸附时，吸附分子首先在表面自由地扩散（物理吸附），失去其运动能量，其间的一部分分子蒸发，残留分子产生热分解而固定在吸附处（化学吸附）。
这时，如果器件的功函数小于吸附分子的电子亲和力，则吸附分子将从器件夺取电子而变成负离子吸附。
具有负离子吸附倾向的气体最典型的是O2，称为氧化型气体或电子接收性气体。
如果器件的功函数大于吸附分子的离解能，吸附分子将向器件释放电子，而成为正离子吸附。
具有这种正离子吸附倾向的气体有H2、CO、碳氢化合物和酒类等，称为还原型气体或电子供给性气体。
目前可用于检测气体的敏感元件有很多种，如SnO2，ZnO，Fe2O3和气敏元件等。
它们共同的特点是可以检测多种不同的气体，但对气体的选择性较差。
这种非单一选择性是由其敏感机理所决定的，虽然可以采用添加适量的贵重金属Pt、Pd等方法改善其选择性，但仍然会对其它气体有一定的敏感度。
2 半导体空气传感器TGS26002.1 TGS2600 构成和工作原理空气传感器是半导体气敏传感器中的一种，它构造简单，由传感器基板，气敏元件和传感器盖帽组成。
气敏元件由一个以金属铝做衬底的金属氧化物敏感芯片和一个完整的加热器组成。
利用加热器加热，以侦测气体附着于金属氧化物表面而产生的电阻值的变化。
在检测气体时，传感器的传导率依赖于空气中气体浓度的变化。

基本测量电路： 此传感器要求有两个电压输入：加热器电压 VH
和线路电压 VC。加热器电压 VH 加于集成加热器上 以保持传感器在一个特定的最佳感应温度。电路电压 VC 被加载以便于测量与感应元件串联的负载电阻电压 Vout。此传感器有极性所以电路电压 VC 必须是直流。 可以用一个公共的电源来同时供给 VH 和 VC 以满足传 感器的电气需求。负载电阻 RL 的选择要使报警门限电 压最优化，并使半导体器件的功耗小于 15mw。当目标 气体存在时，传感器功耗在 RS 与 RL 相等时最大。

溶解氧传感器的作用分析
溶解氧传感器的作用分析溶解氧传感器是一种用于测量氧气在水中的溶解量的传感设备，水中溶解氧浓度的连续测量在水处理领域起着以下几点重要的作用：1、污水处理厂活性污泥池中氧的测量和调节以便在生物降解过程中达到高效。
2、水文监测测量河流、湖泊、海洋中氧含量，指示水的质量。
3、水处理：氧含量测量，如饮用水中检测状态（氧气丰富/腐蚀预防等）。
4、鱼塘：氧含测量和调节以便维持最佳的生态和生长条件。
氧在水中的溶解度取决于温度、压力和水中溶解的盐。
溶解氧分析仪传感器是由金电极（阴极）和银电极（阳极）及氯化钾或氢氧化钾电解液组成，氧通过膜扩散进入电解液与金电极和银电极构成测量回路。
当给溶解氧分析仪电极加上0.6～0.8V 的极化电压时，氧通过膜扩散，阴极释放电子，阳极接受电子，产生电流，整个反应过程为：阳极Ag+ClAgCl+2e- 阴极O2+2H2O+4e4OH- 根据法拉第定律：流过溶解氧分析仪电极的电流和氧分压成正比，在温度不变的情况下电流和氧浓度之间呈线性关系。
目前国内本土品牌中并没质量特别好的溶解氧传感器，比较好的是由日本FIGARO公司生产的溶解氧传感器- KDS-25B，汤浅溶解氧传感器KDS-25B是一款独特的原电池式传感器，是专门为水质控制而开发的。
这款溶解氧传感器最显著的特点就是，使用寿命长，不受CO2影响。
KDS-25B 使用特殊酸性电解液，阴极采用惰性金属金，阳极采用金属铅，氧气以扩散的方式通过氟树脂膜参与氧化还原反应，构成一种氧铅蓄电池，然后由内部电阻将氧化还原反应产生的电流转化成电压输出。
产生的电流与溶解氧的浓度成正比，严格地来说是与氧分压成正比（溶解氧含量越高，透过氟树脂膜参与反应的氧分子越多），KDS-25B是环境监测、水质检测的理想传感器之一。

目前主流pm2.5传感器品牌及型号对比介绍
目前国内外主流PM2.5传感器品牌及型号对比介绍近些年，全球的空气污染（PM2.5）都越来越严重，甚至严重影响了人们的生活出行，小编之前在《空气环境监测解决方案-PM2.5传感器》一文中提到过当空气污染处于高峰时则导致法国巴黎交通运行停止；新加坡空气污染创历史新高；印度的空气污染比中国还要严重。
因而改善空气质量势在必行，在全球污染检测、控制、防治的号召下，作为检测PM2.5颗粒物的PM2.5传感器应运而生，发展迅速，目前市面上做PM2.5传感器的厂家很多，不过产品参差不齐，很多人在选择传感器时常在问：哪个品牌的PM2.5传感器好呢？靠谱呢？在此，小编整理了一些目前市面上应用比较广泛以及客户反馈比较好的PM2.5传感器品牌和典型型号，以供大家参考。
目前市面上主要是有红外和激光两种类型的PM2.5传感器，至于它们的具体区别就不详细描述了，红外原理PM2.5传感器由于精度不够主要用于工矿扬尘，检测对象为大粒径、高浓度粉尘，检测级别是mg/m3，无法准确测量PM2.5的浓度，只能检测灰尘污染程度，当然早期的空气净化器也是使用这种原理传感器；后来激光型PM2.5传感器的诞生，可以精确测量PM2.5浓度，主要应用在PM2.5检测领域，可嵌入到家用（车载、手持）空气检测仪、空气净化器中。
此外，激光原理传感器在物联网数据采集、环境质量检测等领域亦有应用。
从应用市场上区分，一般激光型传感器应用于一些中高端高价产品市场，对数据要求比较高，而红外型传感器适宜一些低价低端产品应用，而传感器本身也可以分为工业级和民用级产品。
在民用产品应用市场，应用比较广泛的传感器包含民用级激光PM2.5传感器和红外型PM2.5传感器，一般常用于空气净化器、智能家居、空调、新风系统等场合。
目前激光型灰尘传感器已慢慢占据红外型灰尘传感器的市场，对于民用级的激光PM2.5传感器目前做的比较好的品牌有日本figaro、攀腾Plantower、炜盛，典型型号和对比如下：当然，假如对测量数据要求不高，对价格要求比较便宜的，可以考虑红外型PM2.5传感器，目前市场上红外型PM2.5传感器做的比较好的品牌有韩国三赢syhitech、美国GE、日本夏普Sharp、日本神荣Shinyel，这些品牌占据了低价低端产品很大一块市场，典型型号和对比如下：对于高端高价市场，一般对测试数据要求比较严谨、对产品稳定性、一致性、精度等都要求比较高，这就需要用到工业级的PM2.5传感器，首推英国Alphasense PM2.5传感器/大气粒子监测器 - OPC-N3，这款传感器通常适合用于重度污染的室外城市环境监测，常用于一些气象台、城市环境监测站、大气监测站等场合。

Specifications 1-1 Features * General purpose sensor for a wide range of combustible gases* High sensitivity to LP gas and methane * Low cost * Long life* Uses simple electrical circuit1-2 Applications* Domestic gas leak detectors and alarms * Recreational vehicle gas leak detectors * Portable gas detectors1-3 StructureFigure 1 shows the structure of TGS813. This sensor is a sintered bulk semiconductor composed mainly of tin dioxide (SnO 2). The semiconductor material and electrodes are formed on an alumina ceramic tube. A heater coil, made of 60 micron diameter wire, is located inside the ceramic tube. Lead wires from the sensor electrodes are a gold alloy of 80 microns in diameter. Heater and lead wires are spotwelded to the sensor pins which have been arranged to fit a 7-pin miniature tube socket.The sensor base and cover are made of Nylon 66, conforming to UL 94H B (Authorized Material Standard). The deformation temperature for this material is in excess of 240˚C. The upper and lower openings in the sensor case are covered with a flameproof double layer of 100 mesh stainless steel gauze (SUS316). Independent tests confirm that this mesh will prevent a spark produced inside the flameproof cover from igniting an explosive 2:1 mixture of hydrogen/oxygen.1-4 Basic measuring circuitFigure 2 shows the basic measuring circuit for use with TGS813. Circuit voltage (Vc) is applied across the sensor element which has a resistance between the sensor’s two electrodes and the load resistor (R L ) connected in series. The sensor signal (V RL ) is measured indirectly as a change in voltage across the R L . The Rs is obtained from the formula shown at the right.Fig. 1 - Sensor structureFig. 2 - Basic measuring circuitVc- V RLV RLRs = x R LFormula to determine RsSensor elementFig. 3 - Sensor dimensions1-5 Circuit & operating conditionsThe ratings shown below should be maintained at all times to insure stable sensor performance:1-6 Specifications NOTE 1Mechanical Strength:The sensor shall have no abnormal findings in its structure and shall satisfy the above electrical specifications after the following performance tests:Withdrawal Force - Vibration - Shock -withstand force > 5kg in eachdirectionfrequency-1000c/min., totalamplitude-4mm, duration-one hour, direction-verticalacceleration-100G, repeated 5timesNOTE 1: Sensitivity characteristics are obtained under the following standard test conditions:(Standard test conditions)Temperature and humidity: 20 ± 2˚C, 65 ± 5% RH Circuit conditions:Vc = 10.0±0.1V AC/DC V H = 5.0±0.05V AC/DC R L = 4.0kΩ ± 1%Preheating period: 7 days or more under standard circuit conditions17ø±0.516.5±0.56.5±0.59.5ø1ø±0.0545˚45˚132645u/m:mm1-7 DimensionsTop viewSide viewBottom view2. Basic Sensitivity Characteristics 2-1 Sensitivity to various gasesFigure 4 shows the relative sensitivity of TGS813 to various gases. The Y-axis shows the ratio of the sensor resistance in various gases (Rs) to the sensor resistance in 1000ppm of methane (Ro).Using the basic measuring circuit illustrated in Figure 2, these sensitivity characteristics provide the sensor output voltage (V RL ) change as shown in Figure 5.NOTE :All sensor characteristics in this technical brochure represent typical sensor characteristics. Since the Rs or output voltage curve varies from sensor to sensor, calibration is required for each sensor (for additional information on calibration, please refer to the Technical Advisory ‘Technical Information on Usage of TGS Sensors for Toxic and Explosive Gas Leak Detectors’).12-2 Temperature and humidity dependencyFigure 6 shows the temperature and humidity dependency of TGS813. The Y-axis shows the ratio of sensor resistance in 1000ppm of methane under various atmospheric conditions (Rs) to the sensor resistance in 1000ppm of methane at 20˚C/65%RH (Ro).under various ambient conditionsTable 1 - Temperature and humidity dependency(typical values of Rs/Ro for Fig. 6)Table 1 shows a chart of values of the sensor’s resistance ratio (Rs/Ro) under the same conditions as those used to generate Figure 6.Figure 7 shows the sensitivity curve for TGS813 to methane under several ambient conditions. While temperature may have a large influence on absolute Rs values, this chart illustrates the fact that effect on the slope of sensor resistance ratio (Rs/Ro) is not significant. As a result, the effects of temperature on the sensor can easily be compensated.For economical circuit design, a thermistor can be incorporated to compensate for temperature (for additional information on temperature compensation in circuit designs, please refer to the Technical Advisory ‘Technical Information on Usage of TGS Sensors for Toxic and Explosive Gas Leak Detectors’).1010Rs (kΩ)102-6 Initial actionclean air.process is called “Initial Action”.circuit be incorporated into the detector’s design (TGS Sensors for Toxic and Explosive Gas Leak Detectors’). This is especially recommended for intermittent-operating devices such as portable gas detectors.2-7 Long-term characteristicsFigure 13 shows long-term stability of TGS813 as measured for more than 8 years. The sensor is first energized in normal air. Measurement for confirming sensor characteristics is conducted under ambient air conditions rather than in a temperature/humidity controlled environment. The cyclic change in sensitivity corresponds to the seasonal changes of temperature/humidity in Japan (peak T/H conditions occur in July, as corresponds with the sensitivity peaks in this chart ). The Y-axis represents the ratio of sensor resistance in 1000ppm of methane on the date tested (Rs) to sensor resistance in 1000ppm of methane at the beginning of the test period (Ro).As this chart illustrates, TGS813 shows stable characteristics over a very long period of time.Fig. 12 - Long term stability(Ro = Rs on day 1)3 Cautions3-1 Situations which must be avoided1) Exposure to silicone vaporsIf silicone vapors adsorb onto the sensor’s surface, the sensing material will be coated, irreversibly inhibiting sensitivity. Avoid exposure where silicone adhesives, hair grooming materials, or silicone rubber/putty may be present.2) Highly corrosive environmentHigh density exposure to corrosive materials such as H2S, SOx, Cl2, HCl, etc. for extended periods may cause corrosion or breakage of the lead wires or heater material.3) Contamination by alkaline metalsSensor drift may occur when the sensor is contam-inated by alkaline metals, especially salt water spray.4) Contact with waterSensor drift may occur due to soaking or splashing the sensor with water.5) FreezingIf water freezes on the sensing surface, the sensing material would crack, altering characteristics.6) Application of excessive voltageIf higher than specified voltage is applied to the sensor or the heater, lead wires and/or the heater may be damaged or sensor characteristics may drift, even if no physical damage or breakage occurs.7) Application of voltage on lead wiresOn six-pin type sensors, if a voltage is applied on the lead wires between pins 1 and 3 and/or pins 4 and 6, this would cause breakage of the lead wires.8) Operation in zero/low oxygen environment TGS sensors require the presence of around 21% (ambient) oxygen in their operating environment in order to function properly and to exhibit characteristics described in Figaro’s product literature. TGS sensors cannot properly operate in a zero or low oxygen content atmosphere.3-2 Situations to be avoided whenever possible1) Water condensationLight condensation under conditions of indoor usage should not pose a problem for sensor performance.H owever, if water condenses on the sensor’s surface and remains for an extended period, sensor characteristics may drift.2) Usage in high density of gasSensor performance may be affected if exposed to a high density of gas for a long period of time, regardless of the powering condition.3) Storage for extended periodsWhen stored without powering for a long period, the sensor may show a reversible drift in resistance according to the environment in which it was stored. The sensor should be stored in a sealed bag containing clean air; do not use silica gel. Note that as unpowered storage becomes longer, a longer preheating period is required to stabilize the sensor before usage. 4) Long term exposure in adverse environment Regardless of powering condition, if the sensor is exposed in extreme conditions such as very high humidity, extreme temperatures, or high contamination levels for a long period of time, sensor performance will be adversely affected.5) VibrationExcessive vibration may cause the sensor or lead wires to resonate and break. Usage of compressed air drivers/ultrasonic welders on assembly lines may generate such vibration, so please check this matter.6) ShockBreakage of lead wires may occur if the sensor is subjected to a strong shock.7) SolderingIdeally, sensors should be soldered manually. For soldering conditions of 8-series gas sensors, refer to Technical Advisory for Soldering 8-type Gas Sensors. 8) PolarityIf the polarity of Vc is reversed during powering, sensor characteristics may temporarily become unstable.15 24 36Figaro USA Inc. and the manufacturer, Figaro Engineering Inc.

FIGARO CANNOT ASSUME ANY RESPONSIBILITY FOR ANY USE OF ITS SENSORS IN A PRODUCT OR APPLICATION FOR WHICH A SENSOR HAS NOT BEEN SPECIFICALLY TESTED BY FIGARO.1. Basic Information and Specifications 1-1 Features* Linear output * Compact size* Small sensitivity to alcohol* Sensitive to hydrogen, methane, and LP gas * Meets RoHS requirements 1-2 Applications* Hydrogen and combustible gas leak detectors for fuel cell applications1-3 StructureFigure 1 shows the structure of TGS6812. The sensor is comprised of two elements: element (D) which is sensitive to combustible gases, and a reference element (C) which does not have sensitivity to combustible gases. The sensing element (D) is made of alumina doped with catalysts, while the reference element (C) is made of alumina. Both coils are made of Pt wire, and the wires of both elements (D) and (C) are connected to nickel pins No. 2 & 3 and No. 1 & 4 respectively. The sensor base and cap are made of reinforced Polybutylene Terephthalate (PBT). The upper opening in the cap is covered with a double layer of 100 mesh stainless steel gauze (SUS316). The TGS6812 utilizes a zeolite filter inside the cap for reducing the influence of interference gases.1-4 Basic measuring circuitThe T GS6812 i s c omprised o f t wo e lements: 1) e lement (D) which is sensitive to combustible gases and 2) a reference element (C) which is not sensitive to combustible gases. These elements are installed into a “Wheatstone Bridge”. A variable resistor should be adjusted so that the bridge will produce a stable baseline signal when in an environment free of combustible gases. When combustible gases are present, they will be combusted on the detecting element, causing its temperature to rise. Accordingly the resistance of this element will increase. This results in an “out-of-balance” signal across the bridge and a corresponding change in output voltage which can be measured.Fig. 1 - Sensor structureFig. 2 - Basic measuring circuitTop viewSide viewu/m = mmCapBottom viewBaseDetector sideCompensator side<Pin connection>1-4 : Compensator 2-3 : Detector1-5 Circuit & operating conditionsThe ratings shown below should be maintained at all times to insure stable sensor performance:1-6 Specifications NOTE 1Mechanical Strength:The sensor shall have no abnormal findings in its structure and shall satisfy the above electricalspecifications after the following performance tests: Vibration - Drop test -frequency:10~150H z, accel-eration: 2G, duration:10 times, direction: three dimensions drop onto a cement floor from a height of 250mm, repeated 5 timesNOTE 1:Sensitivity characteristics are obtained under the following standard test conditions:(Standard test conditions)Temperature and humidity: 20 ± 2˚C, 65 ± 5% RH Circuit conditions:V H = 3.0±0.05V AC/DC Preheating period: 30 seconds or more under standard circuit conditions 1-7 DimensionsFig. 3 - Sensor dimensionsAll sensor characteristics shown in this brochurerepresent typical characteristics.

At each measurement point, the sensor was removed from SO 2 and energized in normal air for 10 hours prior to measuring the sensor output.The data demonstrates that TGS6812 shows stable characteristics after exposure to SO 2.Fig. 11 - Durability to hydrogenFig. 12 - Durability to SO 2-101020-101020characteristics after exposure to NO 2. 3-5 Durability to HMDSFigure 14 shows the effect on TGS6812 of exposure to HMDS. The initial point of the graph shows the value of sensor output prior to HMDS exposure. After the initial measurement was taken, the sensor was exposed to 10ppm of HMDS for one hour in total. At each measurement point, the sensor was removed from HMDS and energized in normal air for 1 hour prior to measuring the sensor output.This data demonstrates that TGS6812 shows stable characteristics after exposure to HMDS.3-6 Effects of Air FlowTable 1 shows how the sensor is affected by airflows (refer to Fig. 15 for illustration of airflows in Table 1). This data demonstrates that there is no significant influence on the sensor by an air flow of 3.1 meters/sec.Fig. 14 - Durability to HMDSFig. 15 - Air flow testing direction (ref. Table 1)Table 1 - Effects of air flow on output voltage4 Cautions on Usage of Figaro Gas Sensors4-1 Situations which must be avoided1) Exposure to silicone vaporsIf silicone vapors adsorb onto the sensor’s surface, the sensing material will be coated, irreversibly inhibiting sensitivity. Avoid exposure where silicone adhesives, hair grooming materials, or silicone rubber/putty may be present.2) Highly corrosive environmentHigh density exposure to corrosive materials such as H2S, SOx, Cl2, HCl, etc. for extended periods may cause corrosion or breakage of the lead wires or heater material.3) Contamination by alkaline metalsSensor drift may occur when the sensor is contaminated by alkaline metals, especially salt water spray.4) Contact with waterSensor drift may occur due to soaking or splashing the sensor with water.5) FreezingIf water freezes on the sensing surface, the sensing material would crack, altering characteristics.6) Application of excessive voltageIf higher than specified voltage is applied to the sensor, the lead wires and/or sensor elements may be damaged or sensor characteristics may drift, even if no physical damage or breakage occurs.7) Operation in zero/low oxygen environment TGS6812 requires the presence of a certain amount of oxygen in its operating environment in order to generate a combustion reaction of gas on the sensor’s surface. It cannot properly operate in a zero or low oxygen content atmosphere.8) Excessive exposure to alcoholIf TGS6812 is exposed to high concentrations of alcohol (such as 10,000ppm or more) for a long period, the filter may become saturated. In this case, the sensor would show a lower resistance in alcohol than indicated in Figure 4.9) VibrationExcessive vibration may result in zero drift or cause the sensor or lead wires to resonate and break. Usage of compressed air drivers/ultrasonic welders on assembly lines may generate such vibration, so tests should be conducted to verify that there will be no influence on sensor characteristics.10) ShockZero drift and breakage of lead wires may occur if the sensor is subjected to a strong shock. To avoid shock, please keep the sensor in the original packing foam during storage.4-2 Situations to be avoided whenever possible1) Water condensationLight condensation under conditions of indoor usage should not pose a problem for sensor performance.H owever, if water condenses on the sensor’s surface and remains for an extended period, sensor characteristics may drift.2) Usage in high density of gasSensor performance may be affected if exposed to a high density of gas for a long period of time, regardless of the powering condition.3) Storage for extended periodsWhen stored without powering for a long period, the sensor may show a reversible drift in resistance according to the environment in which it was stored. The sensor should be stored in a sealed bag containing clean air; do not use silica gel. Note that as unpowered storage becomes longer, a longer preheating period is required to stabilize the sensor before usage. 4) Long term exposure in adverse environment Regardless of powering condition, if the sensor is exposed in extreme conditions such as very high humidity, extreme temperatures, or high contamination levels for a long period of time, sensor performance will be adversely affected.5) SolderingIdeally, sensors should be soldered manually.H owever, wave soldering can be done under the following conditions:a) Suggested flux: rosin flux with minimal chlorineb) Speed: 1-2 meters/min.c) Preheating temperature: 100±20˚Cd) Solder temperature: 250±10˚Ce) Up to two passes through wave soldering machine allowed Results of wave soldering cannot be guaranteed if conducted outside the above guidelines since someFigaro USA Inc. and the manufacturer, Figaro Engineering Inc.
