该模块具有灵敏度高、反应速度快、抗干扰能力强等优点,广泛应用于智能家居、安防监控、医疗保健等领域。
二、SR602 人体感应模块的工作原理SR602 人体感应模块基于热释电效应原理工作。
当人体进入模块的检测范围时,人体会发射红外辐射,这些辐射被模块接收并转换为电信号。
电信号的大小与红外辐射的强度成正比,因此当人体进入检测范围时,模块输出的电压会相应地发生变化。
三、SR602 人体感应模块的代码编写以下是一个基于 Arduino 的 SR602 人体感应模块代码示例:```c// 定义模块连接的引脚const int sensorPin = A0;void setup() {// 设置传感器引脚为输入pinMode(sensorPin, INPUT);}void loop() {// 读取传感器引脚的值int sensorValue = analogRead(sensorPin);// 判断传感器值是否超过阈值if (sensorValue > 600) {// 当人体进入检测范围时,执行相应操作Serial.println("人体进入检测范围");} else {// 当人体离开检测范围时,执行相应操作Serial.println("人体离开检测范围");}// 等待 100 毫秒,进行下一次循环delay(100);}```四、SR602 人体感应模块的应用领域SR602 人体感应模块广泛应用于各种场景,例如:1.智能家居:用于自动控制照明、空调等设备,实现节能和人性化家居环境。
AD602:
AD602:双通道、低噪声、宽带可变增益放⼤器(增益范围-10 dB⾄+30 dB)AD600/AD602均为双通道、低噪声、可变增益放⼤器,并针对超声成像系统应⽤进⾏了优化,但同样适⽤于任何要求精确增益、低噪声、低失真和宽带宽的应⽤。
每个独⽴通道均提供0 dB⾄+40 dB(AD600)/-10 dB⾄+30 dB(AD602)增益。
AD602的增益较低,可改善输出的信噪⽐(SNR)。
不过,两款产品均具有相同的1.4 nV/√Hz输⼊噪声谱密度。
dB增益与控制电压成正⽐关系,经过精密校准,⽽且不随电源电压和温度⽽变化。
为实现⾼难度的性能⽬标,ADI公司开发出⼀种专有电路形式X-AMP®。
X-AMP的每个通道均含有0 dB⾄-42.14 dB可变衰减器,后接⾼速固定增益放⼤器。
这样,放⼤器永远不必处理较⼤输⼊,并且还可以利⽤负反馈来精确定义增益和动态范围。
衰减器以7级R-2R梯形⽹络的形式实现,具有经激光调整⾄±2%的100Ω输⼊电阻。
触点之间的衰减为6.02 dB,增益控制电路提供这些触点之间的连续插值,由此便可获得以dB为单位的线性控制功能。
增益控制接⼝为完全差分接⼝,提供约15 MΩ的输⼊电阻以及由内部基准电压定义的32 dB/V(即31.25 mV/dB)⽐例因⼦。
此接⼝的响应时间不到1 µs。
每个通道还具有独⽴的选通设置,可以选择性阻⽌信号传输,并将直流输出电平设置在输出地电压的数毫伏范围以内。
选通控制输⼊为TTL/CMOS兼容。
AD600的最⼤增益为41.07 dB,AD602的最⼤增益为31.07 dB;两种型号的-3 dB带宽标称值均为35 MHz,基本上与增益⽆关。
1 V均⽅根输出和1 MHz噪声带宽的SNR典型值为76 dB(AD600)/86 dB(AD602)。
在100 kHz⾄10 MHz范围内,振幅响应平坦度为±0.5 dB;超出此频率范围时,所有增益设置的群延迟变化幅度均⼩于±2 ns。

Main PC Board3.2Ambient TemperatureThe Sensing head can operate in an ambient temperature of 0 to 70°C (32to 158°F). The Sensing head in the high temperature model (-HT) can operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any cooling required. The Sensing head can operate up to 200°C (392°F) using the water cool jacket accessory OS100-WC (See Fig. 3-6).There is a warm up period of 3 minutes after power up. After the warm up period, temperature measurement can be made.When the ambient temperature around the sensor head changes abruptly,the sensor head goes through thermal shock. It takes a certain amount of time for the sensor head to stabilize to the new ambient temperature. For example, it takes about 30 minutes for the sensor head to stabilize going from 25°C to 50°C (77 to 122°F) ambient temperature.The sensor head dimensions are shown in Fig. 3-2.Figure 3-2.

高可靠微波感应人体传感器
高可靠微波感应人体传感器这里介绍的微波感应控制器和市场上常见的简易型微波感应控制器相比较,因为采用专用的微处理集成电路HT7610A,不但检测灵敏度度高,探测范围宽,而且工作非常可靠,误报率极低,能在-25~+45度的温度范围内稳定工作,最适和在中、高档防盗报警系统中作人体移动检测传感头使用。
1。
工作原理微波感应控制器使用直径9厘米的微型环形天线作微波探测,其天线在轴线方向产生一个椭圆形半径为0~5米(可调)空间微波戒备区,当人体活动时其反射的回波和微波感应控制器发出的原微波场(或频率)相干涉而发生变化,这一变化量经HT7610A进行检测、放大、整形、多重比较以及延时处理后由白色导线输出电压控制信号。
高可靠微波感应控制器内部由环形天线和微波三极管组成一个工作频率为2.4GHz的微波振荡器,环形天线既做发射天线也可接收由人体移动而反射的回波。
内部微波三极管的半导体PN结混频后差拍检出微弱的频移信号(即检测到人体的移动信号) ,微波专用微处理器HT7610A首先去除幅度太小的干扰信号只将一定强度的探测频移信号转化成宽度不同的等幅脉冲,电路只识别脉冲足够宽的单体信号,如人体、车辆其鉴别电路才被触发,或者两秒内有2~3个窄脉冲,如防范边沿区人走动2~3步,鉴宽电路也被触发,启动延时控制电路工作。
如果是较弱的干扰信号,如小体积的动物,远距离的树木晃动、高频通讯信号、远距离的闪电和家用电器开关时产生的干扰予以排除。
最后输HT7610A鉴别出真正大物体移动信号时,控制电路被触发,输出2秒左右的高电平,并有LED2同步显示,输出方式为电压方式,有输出时为高电平(8伏以上),没有输出时为低电平。
微波专用的微处理器HT7610A的时钟频率为16KH,当初次加电时,系统将闭锁60秒,期间完成微处理器的初始化并建立电场,这时LED 闪亮60秒后熄灭,系统自动进入检测状态,当检测到有效信号时,将有2秒信号输出,并由指示灯LED同步点亮。

二. 雷达微波感应器
雷达微波感应器灯具外观特点: 感应器不需要外露探头,感应天线板内置在 灯具内。
雷达微波感应器的工作原理:
利用电磁波的多普勒原理来做的,任何波都有反射的 特性,当一定频率的波碰到阻挡物的时候,就会有一部分 的波被反射回来,如果阻挡物是静止的,反射波的波长就 是恒定的,如果阻挡物是向波源运动,反射波的波长就比 波源的波长来得短,如果阻挡物是向远离波源的方向运 动,反射波的波长就比波源的波长来的长,波长的变化, 就意味着频率的变化。微波感应正是通过反射波的变化知 道有运动物体逼近或远离的,然后把这种变化转换成电信 号输出。

1)这种探头是以探测人体辐射为目标的,所以热释 电元件对波长为10uM左右的红外辐射非常敏感。 2)为了仅仅对人体的红外辐射敏感,在它的辐射照 面通常覆盖有特殊的菲涅尔滤光片,使环境的干扰受到 明显的控制作用。 3)一旦人侵入探测区域内,人体红外辐射通过部分 镜面聚焦,并被热释电元接收,但是两片热释电元接收 到的热量不同,热释电也不同,不能抵消,经信号处理 而报警。 4)菲泥尔滤光片根据性能要求不同,具有不同的焦 距(感应距离),从而产生不同的监控视场,视场越 多,控制越严密。
影响感应距离的因素: 1.检查透镜或者感应窗口是否有灰尘覆盖,注意小 心透镜取下和安装,可以干净的静电布擦拭; 2. 红外线热释电传感器对人体的敏感程度还和人的 运动方向关系很大。红外线热释电传感器对于径向 移动反应最不敏感,而对于横切方向 (即与半径垂直 的方向)移动则最为敏感;
3.环境温度和人体温度接近时,探测和灵敏度明显 下降,有时造成短时失灵 ; 4.被动红外穿透力差,人体的红外辐射容易被遮 挡,也不易被探头接收。 5.灯管安装时角度稍作调整,探头方向尽量面向需 要感应的区域。

九、应用信息
1、振荡器工作频率计算
LD602仅需一个外接电容CT和一个上拉电阻RT即可设置振荡器的工作频率,上电后通过上拉电阻RT对CT电容进行充电,当电容上电压充电到0.6Vdd电压时,双门限比较器动作开启内部下拉27K电阻对CT进行放电,当电容上电压放电到0.4Vdd时,双门限比较器动作关闭内部下拉电阻,CT电容再一次通过上拉电阻RT进行充电到0.6Vdd,这样周期性的对电容进行充放电,从而得到稳定的工作振荡频率,近似的工作频率和电阻电容之间关系由公式TOSC=0.4CTRT*RT/RT-27决定,(电阻单位为K,电容单位为nF,Tosc单位为uS),频率由f=1⁄TOSC确定,如RT=680K,CT=1nF时,对应的延时时间约为30秒。
选择上拉电阻RT时,需大于80K以上的电阻。
(内置27K电阻可能会在后续版本中修改,请关注最新版的Datasheet).
振荡器内部工作原理
2、触发延时时间定时器和触发封锁时间定时器
LD602定义触发延时定时器的时间为Tx,触发封锁时间定时器的时间Ti,两者的比例系数为K,即K=Tx/Ti,LD602的K值默认为14,封装为SOP8封装,为适应不同的应用场合,如有其他K值需要(3<K<48)请咨询本司销售。
触发延时时间定时器主要用于信号触发后进入持续输出高电平时间阶段,其定时时间约为100000个Tosc时钟周期,即Tx为固定的100000TOSC,经100000个Tosc时钟周期后,OUT引脚开始输出低电平进入触发封锁时间定时器阶段,触发封锁阶段OUT引脚是持续输出低电平,但振荡器继续工作直至Ti结束。
触发延时和封锁延时
3、可重复触发和不可重复触发功能
当引脚A=”0”时,工作方式设置为不可重复触发模式,所谓不可重复触发模式指的是当Vc高电平有效时,触发信号Vs的第一个上升沿跳变将使OUT脚输出高电平,芯片进入Tx触发延时定时和Ti触发封锁定时阶段,在此阶段内如果再来Vs触发信号,Vs触发信号
将是无效的,一直到Tx和Ti定时结束,触发信号Vs重新有效
不可重复触发模式
当引脚A=”1”时,工作方式设置为可重复触发模式,所谓可重复触发模式指的是当Vc
高电平有效时,触发信号Vs的第一个上升沿跳变将使OUT脚输出高电平,芯片进入Tx触
发延时定时阶段,在Tx阶段内Vs一直有效,在此阶段内如果有Vs上升沿跳变再次触发,
芯片将重新计数Tx触发延时定时,一直到Tx定时结束才使Vs触发信号无效进入Ti封
锁定时阶段,在Ti封锁定时结束后,触发信号Vs才重新有效。
可重复触发模式
4、PIR红外热释电应用建议
一般最常用的热释电红外传感器的灵敏度是沿长方形方向横向移动才是最高的,所以为了在各个方向灵敏度相近,成品在装配布置时,建议采用45度安装,并且使用菲涅尔(Fresnel)透镜。
热释电红外传感器容易受各种热源,光源,辐射,环境温度等干扰,为了尽量避免误触发,请尽量远离火源、空调、窗口等。
在电路布线上,PIR与其他器件的连线越短越好,多层板布线时,连线下方不要走线,尤其不能走大电流的走线。
PIR感应部分的电路要单独隔离并有单独的接地,探头电源上接一个100nF的电容到地,并尽量与探头电源接近。
如果允许,在电源上串联一个47K电阻,并且并联一个100uF的电解电容,在D/S之间接一个200pF 电容等各种方法,尽量避免干扰信号进入处理芯片。
十、封装消息
LD602用的是标准的SOP8通用封装,在立创商城下载一个SOP8封装就可以用。
