接近传感器(Proximity sensor)
●接近传感器是一种具有感知物体接近能力的器件，它利用位移传感器对接近的物体具有敏感特性来识别物体的接近，并输出相应开关信号，其发射器会发射经过脉冲信号调制的红外光信号，经过物体反射的光被接收器接收，通过信号处理得到与距离相关的信息。广泛应用于手机、平板、智能家居等领域。
●Proximity sensor is a device with the ability to perceive the proximity of objects. It uses the displacement sensor to identify the proximity of objects with sensitive characteristics, and output the corresponding switch signal.The transmitter will emit infrared light signal modulated by pulse signal, and the light reflected by the object is received by the receiver, and information related to distance is obtained through signal processing. Widely used in mobile phones, tablets, smart home and other fields.
