XYC-PIR203B-S0 这款抗干扰抗白光的PIR热释电红外传感器是如何做到高灵敏度和优越信噪比的？
首先它是利用温度变化的特征来探测红外线的辐射，
其次他是采用双元补偿的方法抑制温度变化产生的干扰，提高了传感器的工作稳定性。
再者它采用阻容滤波电路、阻容选频电路，增强了传感器的电磁兼容性，使传感器对射频干扰（RFI）的抗扰度高，
所以这款产品应用广泛，例如防盗报警器、感应门、自动灯具、智能玩具、安防监控摄像机等。

The XYC-PIR203B-S0 pyroelectric infrared sensor uses the characteristic of temperature change to

detect the infrared radiation,it uses the binary compensation method to

suppress the interference caused by the temperature change, thereby

improving the working stability of the sensor. The resistance-capacitance

filtering circuit and the resistance-capacitance frequency selective circuit are

used to enhance the electromagnetic compatibility of the sensor, so that the

sensor has higher immunity to radio frequency interference (RFI). The

product can be used in burglar alarms, induction doors, automatic

lamps,intelligent toys and security surveillance cameras, etc.
