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：　　1、容易受各种热源、光源干扰 　　2、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。 　　3、易受射频辐射的干扰。 　　4、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……

被动式PIR热释电红外传感器的工作原理与特性 　　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……

随着社会的发展，各种方便于生活的自动控制系统开始进入了人们的生活，以热释电红外传感器为核心的自动门系统就是其中之一。 热释电红外传感器是基于热电效应原理的热电型红外传感器。其内部的热电元由高热电系数的铁钛酸铅汞陶瓷以及钽酸锂、硫酸三甘铁等配合虑光镜片窗口组成，其极化随温度的变化而变化。热释电红外传感器由传感探……

ALS环境光传感器可以感知周围光线情况，并告知处理芯片自动调节显示器背光亮度，降低产品的功耗。例如，在手机、笔记本、平板电脑等移动应用中，显示器消耗的电量高达电池总电量的30%，采用环境光传感器可以最大限度地延长电池的工作时间。另一方面，ALS环境光传感器有助于显示器提供柔和的画面。当环境亮度较高时，使用ALS环境光传感器的液晶显示器会自动调成高亮度。当外界环境较暗时，显示器就会调成低亮度。 ALS环境光传感器具有暗电流小，低照度响应，灵敏度高，电流随光照度增强呈线性变化等特性；内置
