pir传感器工作原理讲解
pir传感器工作原理讲解一、引言PIR传感器（Passive Infrared Sensor），即被动式红外传感器，是一种广泛应用于安防领域的传感器。
它利用人体发出的红外线辐射来检测人体的存在，从而实现自动感应和控制。
本文将详细介绍PIR传感器的工作原理。
二、红外辐射与热能人体作为一个温暖的物体，会发出红外线辐射。
红外线是一种电磁波，波长在0.75至1000微米之间，是可见光的一种延伸。
人眼无法直接感知红外线，但PIR传感器可以接收并处理这种辐射。
三、传感器结构PIR传感器通常由两个探测区域组成，每个探测区域都覆盖一个锥形视野。
传感器的外壳上还有一个镜片，用来聚焦红外辐射。
镜片的材质和形状能够影响传感器的探测距离和角度。
四、红外辐射的感知当有人或其他物体进入传感器的监测范围内时，人体发出的红外辐射会通过镜片聚焦到传感器的探测区域上。
传感器内部的红外感测元件会接收到这些红外辐射。
五、红外感测元件传感器内部的红外感测元件通常采用双热电偶，也叫做焦耳效应传感器。
双热电偶由两个热电偶电极组成，它们被放置在一个特殊的材料中。
当热电偶感受到红外辐射时，两个电极之间会产生微小的电压差。
六、信号放大与处理传感器会将双热电偶产生的微小电压差信号放大，并进行处理。
通过对信号的放大和滤波处理，可以有效地区分人体的红外辐射信号和其他干扰信号。
七、感知区域划分传感器内部的电路会将探测区域划分成多个像素。
每个像素都可以独立感知红外辐射的变化。
通过对不同像素的信号进行比较和分析，可以确定人体的位置和移动方向。
八、灵敏度与延迟设置PIR传感器通常具有灵敏度和延迟时间的设置。
灵敏度调节可以控制传感器对红外辐射的感知范围，高灵敏度可感知较小的红外辐射变化。
延迟时间设置则可以调整传感器在感知到红外辐射后的响应时间。
九、应用领域PIR传感器广泛应用于安防领域，如室内外监控系统、入侵报警系统等。
它还可以用于节能控制领域，如智能照明系统、自动门控制系统等。
人体感说明书应器HC-SR501
人体红外传感器(PIR)模块HC-SR501工作原理：人体都有恒定的体温，一般在37度，所以会发出特定波长10UM左右的红外线，被动式红外探头就是靠探测人体发射的10UM左右的红外线而进行工作的。
人体发射的10UM左右的红外线通过菲泥尔滤光片增强后聚集到红外感应源上。
红外感应源通常采用热释电元件，这种元件在接收到人体红外辐射温度发生变化时就会失去电荷平衡，向外释放电荷，后续电路经检测处理后就能产生报警信号。
热释电效应：当一些晶体受热时，在晶体两端将会产生数量相等而符号相反的电荷。
这种由于热变化而产生的电极化现象称为热释电效应。
菲涅耳透镜：根据菲涅耳原理制成，菲涅耳透镜分为折射式和反射式两种形式，其作用一是聚焦作用，将热释的红外信号折射（反射）在PIR上；二是将检测区内分为若干个明区和暗区，使进入检测区的移动物体能以温度变化的形式在PIR上产生变化热释红外信号，这样PIR就能产生变化电信号。
使热释电人体红外传感器(PIR)灵敏度大大增加。
模块参数：1.工作电压：DC5V至20V2.静态功耗：65微安3.电平输出：高3.3V，低0V4.延时时间：可调(0.3秒~18秒)5.封锁时间：0.2秒6.触发方式：L不可重复，H可重复，默认值为H(跳帽选择)7.感应范围：小于120度锥角，7米以内8.工作温度：-15~+70度模块特性：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左右的红外辐射必须非常敏感。
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泥尔滤光片，使环境的干扰受到明显的控制作用。
3、被动红外探头，其传感器包含两个互相串联或并联的热释电元。
而且制成的两个电极化方向正好相反，环境背景辐射对两个热释元件几乎具有相同的作用，使其产生释电效应相互抵消，于是探测器无信号输出。
4、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。
人体热释电红外传感器PIR原理
1.人体热释电红外传感器PIR原理详解在电子防盗、人体探测器领域中，被动式热释电红外探测器的应用非常广泛，因其价格低廉、技术性能稳定而受到广大用户和专业人士的欢迎。
被动式热释电红外探头的工作原理及特性：人体都有恒定的体温，一般在37度，所以会发出特定波长10μm左右的红外线，被动式红外探头就是靠探测人体发射的10μm左右的红外线而进行工作的。
人体发射的10μm 左右的红外线通过菲涅尔滤光片增强后聚集到红外感应源上。
红外感应源通常采用热释电元件，这种元件在接收到人体红外辐射温度发生变化时就会失去电荷平衡，向外释放电荷，后续电路经检测处理后就能产生报警信号。
(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10μm 左右的红外辐射必须非常敏感。
(2)为了仅仅对红外辐射敏感，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)被动红外探头，其传感器包含两个互相串联或并联的热释电元。
而且制成的两个电极化方向正好相反，环境背景辐射对两个热释元件几乎具有相同的作用，使其产生释电效应相互抵消，于是探测器无信号输出。
(4)一旦人侵入探测区域，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。
(5)菲涅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。
被动式热释电红外探头的优缺点：优点：本身不发任何类型的辐射，器件功耗很小，隐蔽性好。
价格低廉。
缺点：◆容易受各种热源、光源干扰◆被动红外穿透力差，人体的红外辐射容易被遮挡，不易被探头接收。
◆易受射频辐射的干扰。
◆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。
抗干扰性能：1.防小动物干扰探测器安装在推荐地使用高度，对探测围地面上地小动物，一般不产生报警。
2.抗电磁干扰探测器的抗电磁波干扰性能符合GB10408中4.6.1要求，一般手机电磁干扰不会引起误报。
浅谈人体红外传感器(PIR)模块HC-SR501
浅谈人体红外传感器(PIR)模块HC-SR501红外线感应器红外智能节电开关是基于红外线技术的自动控制产品，当有人进入感应范围时，专用传感器探测到人体红外光谱的变化，自动接通负载，人不离开感应范围，将持续接通；人离开后，延时自动关闭负载。
人到灯亮，人离灯熄，亲切方便，安全节能，更显示出人性化关怀。
红外线感应器是根据红外线反射的原理研制的，属于一种智能节水、节能设备。
包括感应水龙头、自动干手器、医用洗手器、自动给皂器、感应小便斗冲水器、感应便器。
这是标准的称呼，也有称为热红外人体感应器。
原理这种是通过红外线反射原理，当人体的手或身体的某一部分在红外线区域内，红外线发射管发出的红外线由于人体手或身体摭挡反射到红外线接收管，通过集成线路内的微电脑处理后的信号发送给脉冲电磁阀，电磁阀接受信号后按指定的指令打开阀芯来控制头出水；当人体的手或身体离开红外线感应范围，电磁阀没有接受信号，电磁阀阀芯则通过内部的弹簧进行复位来控制的关水。
红外线在光谱中波长自0.76至400微米的一段称为红外线，红外线是不可见光线。
所有高于绝对零度（-273.15℃）的物质都可以产生红外线。
现代物理学称之为热射线。
医用红外线可分为两类：近红外线与远红外线。
太阳光谱红外线是太阳光线中众多不可见光线中的一种，由德国科学家霍胥尔于1800年发现，又称为红外热辐射，他将太阳光用三棱镜分解开，在各种不同颜色的色带位置上放置了温度计，试图测量各种颜色的光的加热效应。
结果发现，位于红光外侧的那支温度计升温最快。
因此得到结论：太阳光谱中，红光的外侧必定存在看不见的光线，这就是红外线。
也可以当作传输之媒介。
太阳光谱上红外线的波长大于可见光线，波长为0.75～1000μm。
红外线可分为三部分，即近红外线，波长为（0.75-1）～（2.5-3）μm之间；中红外线，波长为（2.5-3）～（25-40）μm之间；远红外线，波长为（25-40）～l000μm 之间。
