(11)1 Overview Thermistors电热调节器简介1.1 General总则Resistance elements come in many types conforming to different standards, capable of different temperature ranges, with various sizes and accuracies available. But they all function in the same manner: each has a pre-specified resistance value at a known temperature which changes in a predictable fashion. In this way, by measuring the resistance of the element, the temperature of the element can be determined from tables, calculations or instrumentation. These resistance elements are the heart of the RTD (Resistance Temperature Detector or short: Thermistor). Generally, a bare resistance element is too fragile and sensitive to be used in its raw form, so it must be protected by incorporating it into an housing.电阻元器件满足不同的标准，能够适用不同的温度范围，可满足多种尺寸和精度要求。

After reaching the minimal supply voltage and allowing for the maximal power-up time of 1 ms, the sensor is ready for I2C communication. The quickest way to measure temperature is pseudo-coded on the right-hand side of Figure 1. Using the conversion formulae given in equations ( 1 ) and ( 2 ), the digital signal can be translated into temperature readings.For Code resources, embedded drivers, and CAD files, please refer to the SHT4x files available on GitHub and SnapEDA.2 Sensor Specifications2.1 Sensor PerformanceTable 1. General temperature sensor specifications.Figure 2. STS40 typical and maximal temperature accuracy.1For definition of typ. and max. accuracy, please refer to the document “Sensirion Humidity Sensor Specification Statement”.2The stated repeatability is 3 times the standard deviation (3σ) of multiple consecutive measurement values at constant condit ions and is a measure for the noise on the physical sensor output. Different repeatability commands are listed in Table 6.3Resolution of A/D converter.4Specified range refers to the range for which the temperature sensor specification is guaranteed.5Depends on heat conductivity of sensor substrate and design-in of sensor in application.6Max. value is < 0.04°C/y.3 Electrical SpecificationsValid for all electrical specifications: Typical values correspond to V DD = 3.3 V and T = 25 °C. Min. and max. values are valid in the full temperature range -40 °C … 125 °C and at declared V DD levels.3.1 Electrical CharacteristicsTable 2. Electrical specifications.3.2 TimingsMax. values are measured at -40°C and 1.08 V supply voltage (based on characterization).Table 3. System timing specifications.3.3 Absolute Maximum RatingsStress levels beyond those listed in Table 4 may cause permanent damage or affect the reliability of the device. Kindly note that the reported values are stress ratings only, implying that functional operation of the device under these conditions is not guaranteed. Ratings are only tested separately.Table 4. Absolute maximum ratings.4 Sensor Operation4.1 I2C CommunicationI2C communication is based on NXP’s I2C-bus specification and user manual UM10204, Rev.6, 4 April 2014. Supported I2C modes are standard, fast mode, and fast mode plus. Data is transferred in multiples of 16-bit words and an 8-bit check sum (cyclic redundancy check = CRC). All transfers must begin with a start condition (S) and terminate with a stop condition (P). To finish a read transfer, send not acknowledge (NACK) and stop condition (P). Addressing a specific slave device is done by sending its 7-bit I2C address followed by an eighth bit, denoting the communicationdirection: “zero” indicates transmission to the slave, i.e. “write”, a “one” indicates a “read” request. Schematics of the I2C transfer types are sketched in Figure 3.Figure 3. I2C transfer types: First a write header is sent to the I2C slave, followed by a command, for example “measure T with highest precision”. After the measurement is finished the read request directed to this I2C slave will be acknowledged and transmission of data will be started by the slave.The I2C address is defined by Sensirion and selectable by choosing from a selection of 0x44, 0x45, or 0x46 before ordering. For ordering details, kindly refer to section 8 and 9.4.2 Data Type & LengthThe I2C bus operates with 8-bit data packages. Information from the sensor to the master has a checksum after every second 8-bit data package. Therefore, the temperature data will always be transmitted in the following way (2 * 8-bit data + 8-bit CRC).4.3 Checksum CalculationFor read transfers each 16-bit data is followed by a checksum with the following propertiesTable 5. Data check sum properties.The master may abort a read transfer after the 16-bit data, if it does not require a checksum.4.4 Command OverviewTable 6. Overview of I 2C commands. If the sensor is not ready to process a command, e.g. because it is still measuring, it will response with NACK to the I2C read header.4.5 Conversion of Signal OutputThe digital sensor signal S T corresponds to temperatures, as described in Eqs. (1), and (2).4.6 Serial NumberEach sensor has a unique serial number that is assigned by Sensirion during production. It is stored in the one-time-programmable memory and cannot be manipulated after production. The serial number is accessible via I 2C and is transmitted as two 16-bit words, each followed by an 8-bit CRC.4.7 Reset & AbortA reset of the sensor can be achieved in three ways:• Soft reset: send the reset command described in Table 6.• I 2C general call: all devices on the I 2C bus are reset by sending the command 0x06 to theI 2C address 0x00. • Power down (incl. pulling SCL and SDA low)Any command that triggers an action at the sensor can be aborted via I 2C general call reset or soft reset.5 Physical Specification5.1 Package DescriptionThe STS4x is provided in a dual flat no lead (DFN) package, and comprises the silicon sensor chip made of silicon, which is hosted on a copper lead frame and overmolded by an epoxy-based mold compound. The exposed bottom side of the leadframe with the metallic contacts is Sn plated, while the side walls are bare copper.While moisture sensitivity level (MSL) 1 according to IPC/JEDEC J-STD-020 is met, we recommend to process the sensors within one year after date of delivery.T =(−45+175∙S T216−1)°C( 1 ) T =(−49+315∙S T216−1)°F( 2 )5.2 Package OutlineFigure 4. Dimensional drawing of the STS4x including package tolerances (units mm). The Pin 1 is identified by the laser dot on the top side and the cutout of the die pad, visible from the bottom.5.3 Land PatternWe recommend designing the land pattern to the used PCB and soldering process together with the physical outer dimensions of the sensor. For reference, the land pattern used with Sensirion’s PCBs and soldering processes is given in Figure 5.Soldering of the central die pad is optional.Figure 5. Recommended land pattern (inmm). Details can vary and depend onused PCBs and solder processes. Thereshall be no copper under the sensor otherthan at the pin pads.5.4 Pin Assignment & Laser MarkingFigure 6.

The TSYS01 provides factory calibrated temperature information. It includes a temperature sensing chip and a 24-bit ΔΣ-ADC. The essence of the digital 24-bit temperature value and the internal calibration values lead to highly accurate temperature information accompanied by high measurement resolution.The TSYS01 can be interfaced to any microcontroller by an I2C or SPI interface. This microcontroller has to calculate the temperature result based on the ADC values and the calibration parameters.The basic operating principle is: ∙ Converting temperature into digital 16/24 bit ADC value ∙ Providing calibration coefficients∙ Providing ADC value and calibration coefficients by SPI or I2Cinterface.Absolute maximum ratingsAbsolute maximum ratings are limiting values of permitted operation and should never be exceeded under the worst possible conditions either initially or consequently. If exceeded by even the smallest amount, instantaneousOperational characteristicsDigital inputs (SCLK, SDI, CSB, PS)Pin function tableInterface descriptionPROTOCOL SELECTIONPS pin input level has to be defined in dependence to protocol selection.∙PS = 0 activates SPI.∙PS = 1 activates I2C.I2C INTERFACEA I2C communication message starts with a start condition and it is ended by a stop condition.Each command consists of two bytes: the address byte and command byte.I2C ADDRESS SELECTIONThe I2C address can be selected by CSB pin.∙CSB=1 the address is 1110110x.∙CSB=0 the address is 1110111x.Therefore, two TSYS01 can be interfaced on the same I2C bus.SPI INTERFACEThe serial interface is a 4-wire SPI bus, operating as a slave. CS (chip select), SCLK (serial clock), SDI (serial data in), and SDO (serial data out) are used to interact with the SPI master.Communication with the chip starts when CS is pulled to low and ends when CS is pulled to high.SCLK is controlled by the SPI master and idles low (SCLK low on CS transitions, mode 0).A mode where the clock alternatively idles high is also supported (mode 3).COMMANDSThe commands are the same for SPI and I2C interface.There are four commands:∙Reset∙Read PROM (calibration parameters)∙Start ADC Temperature conversion∙Read ADC Temperature resultRESET SEQUENCEThe Reset sequence has to be sent once after power-on. It also can be used to reset the device ROM from an unknown condition.SPII2CPROM READ SEQUENCEThe PROM Read command consists of two parts. First command sets up the system into PROM readmode. The second part gets the data from the system.Below examples are sequences to read address 3 (command 0xA6).SPII2CCONVERSION SEQUENCEA conversion has to be started by sending this command. The sensor stays busy until conversion is done.When conversion is finished the data can be accessed by using ADC read commandSPIThe last clock will start the conversion which TSYS01 indicates by pulling SDO low. SDO goes high when conversion is completed.I2CWhen the command is sent the TSYS01 stays busy until the conversion is done. All other commandsexcept the reset command will not be executed during this time. When the conversion is finished the data can be accessed by sending a ADC read command, when an acknowledge appears from TSYS01.READ ADC RESULTAfter the conversion command the ADC result is read using ADC read command. Repeated ADC read commands, or command executed without prior conversion will return all 0 as result.SPII2CTemperature calculationCALIBRATION PARAMETERADC24: ADC valueADC16: ADC24 / 256T / °C = (-2) * k4 * 10-21 * ADC164 +4 * k3 * 10-16 * ADC163 +(-2) * k2 * 10-11 * ADC162 +1 * k1 * 10-6 * ADC16 +(-1.5) * k0 * 10-2ADC24: 9378708ADC16: 9378708 / 256 = 36636T / °C = (-2) * 28446 * 10-21 * 366364 +4 * 24926 * 10-16 * 366363 +(-2) * 36016 * 10-11 * 366362 +1 * 32791 * 10-6 * 36636 +(-1.5) * 40781 * 10-2T / °C = 10.5923...8 7 0EXAMPLESerial number: 28 x 5+ 150 = 1430ChecksumIn order to check communication and integrity of PROM content, the PROM includes a checksum.

它可以设置温度控制的上下限，当温度高于上限时，蜂鸣器报警，当低于下限时，发光二极管发光。
本文介绍了数字温度传感器DS18B20的结构特征及控制方法，并对以此传感器和89C51单片机为控制器构成的温度控制系统的工作原理及程序设计进行了相关介绍。

它是带2K 字节闪存可编程可擦除只读存储器的单片机。
单片机的可擦除只读存储器可以反复擦除1000次。
该器件采用ATMEL高密度非易失存储器制造技术制造，与工业标准的MCS-51指令集和输出管脚相兼容。
由于将多功能8位CPU 和闪烁存储器组合在单个芯片中，ATMEL的AT89C51是一种高效微控制器，AT89C2051是它的一种精简版本。
AT89C单片机为很多统嵌入式控制系统提供了一种灵活性高且价廉的方案。
引脚排列如图所示：主要特性：·与MCS-51 兼容·4K字节可编程FLASH存储器·寿命：1000写/擦循环·数据保留时间：10年·全静态工作：0Hz-24MHz·三级程序存储器锁定·128×8位内部RAM·32可编程I/O线·两个16位定时器/计数器·5个中断源·可编程串行通道·低功耗的闲置和掉电模式·片内振荡器和时钟电路1.2.管脚功能说明VCC：供电电压。
GND：接地。
P0口：P0口为一个8位漏极开路双向I/O口，每脚可吸收8TTL门电流。
当P0口的管脚第一次写1时，被定义为高阻输入。
P0能够用于外部程序数据存储器，它可以被定义为数据/地址的第八位。
在FIASH编程时，P0 口作为原码输入口，当FIASH进行校验时，P0输出原码，此时P0外部必须被拉高。
P1口：P1口是一个内部提供上拉电阻的8位双向I/O口，P1口缓冲器能接收输出4TTL门电流。
P1口管脚写入1后，被内部上拉为高，可用作输入，P1口被外部下拉为低电平时，将输出电流，这是由于内部上拉的缘故。
在FLASH编程和校验时，P1口作为第八位地址接收。
P2口：P2口为一个内部上拉电阻的8位双向I/O口，P2口缓冲器可接收，输出4个TTL门电流，当P2口被写“1”时，其管脚被内部上拉电阻拉高，且作为输入。
并因此作为输入时，P2口的管脚被外部拉低，将输出电流。
这是由于内部上拉的缘故。
P2口当用于外部程序存储器或16位地址外部数据存储器进行存取时，P2口输出地址的高八位。
在给出地址“1”时，它利用内部上拉优势，当对外部八位地址数据存储器进行读写时，P2口输出其特殊功能寄存器的内容。
P2口在FLASH编程和校验时接收高八位地址信号和控制信号。
P3口：P3口管脚是8个带内部上拉电阻的双向I/O口，可接收输出4个TTL门电流。
当P3口写入“1”后，它们被内部上拉为高电平，并用作输入。
作为输入，由于外部下拉为低电平，P3口将输出电流（ILL）这是由于上拉的缘故。
P3口也可作为AT89C51的一些特殊功能口，如下表所示：口管脚备选功能P3.0 RXD（串行输入口）P3.1 TXD（串行输出口）P3.2 /INT0（外部中断0）P3.3 /INT1（外部中断1）P3.4 T0（记时器0外部输入）P3.5 T1（记时器1外部输入）P3.6 /WR（外部数据存储器写选通）P3.7 /RD（外部数据存储器读选通）P3口同时为闪烁编程和编程校验接收一些控制信号。
RST：复位输入。
当振荡器复位器件时，要保持RST脚两个机器周期的高电平时间。
ALE/PROG：当访问外部存储器时，地址锁存允许的输出电平用于锁存地址的地位字节。
在FLASH编程期间，此引脚用于输入编程脉冲。
在平时，ALE端以不变的频率周期输出正脉冲信号，此频率为振荡器频率的1/6。
因此它可用作对外部输出的脉冲或用于定时目的。
然而要注意的是：每当用作外部数据存储器时，将跳过一个ALE脉冲。
如想禁止ALE的输出可在SFR8EH地址上置0。
此时， ALE只有在执行MOVX，MOVC指令是ALE才起作用。
另外，该引脚被略微拉高。
如果微处理器在外部执行状态ALE禁止，置位无效。
/PSEN：外部程序存储器的选通信号。
在由外部程序存储器取指期间，每个机器周期两次/PSEN有效。
但在访问外部数据存储器时，这两次有效的/PSEN信号将不出现。
/EA/VPP：当/EA保持低电平时，则在此期间外部程序存储器（0000H-FFFFH），不管是否有内部程序存储器。
注意加密方式1时，/EA 将内部锁定为RESET；当/EA端保持高电平时，此间内部程序存储器。
在FLASH 编程期间，此引脚也用于施加12V编程电源（VPP）。
XTAL1：反向振荡放大器的输入及内部时钟工作电路的输入。
XTAL2：来自反向振荡器的输出。
1.3.振荡器特性:XTAL1和XTAL2分别为反向放大器的输入和输出。
该反向放大器可以配置为片内振荡器。
石晶振荡和陶瓷振荡均可采用。
如采用外部时钟源驱动器件，XTAL2应不接。
有余输入至内部时钟信号要通过一个二分频触发器，因此对外部时钟信号的脉宽无任何要求，但必须保证脉冲的高低电平要求的宽度。
1.4.芯片擦除：整个PEROM阵列和三个锁定位的电擦除可通过正确的控制信号组合，并保持ALE管脚处于低电平10ms 来完成。
在芯片擦操作中，代码阵列全被写“1”且在任何非空存储字节被重复编程以前，该操作必须被执行。
此外，AT89C51设有稳态逻辑，可以在低到零频率的条件下静态逻辑，支持两种软件可选的掉电模式。
在闲置模式下，CPU停止工作。
但RAM，定时器，计数器，串口和中断系统仍在工作。
在掉电模式下，保存RAM的内容并且冻结振荡器，禁止所用其他芯片功能，直到下一个硬件复位为止。
第2章温度采集部分设计2.1.DS18B20 技术性能描述独特的单线接口方式，DS18B20在与微处理器连接时仅需要一条口线即可实现微处理器与DS18B20的双向通讯。
测温范围为－55℃～+125℃，固有测温分辨率0.5℃。
支持多点组网功能，多个DS18B20可以并联在唯一的三线上，最多只能并联8个，实现多点测温，如果数量过多，会使供电电源电压过低，从而造成信号传输的不稳定。
工作电源: 3~5V/DC。
在使用中不需要任何外围元件；测量结果以9~12位数字量方式串行传送；不锈钢保护管直径Φ6 。
