XYC-PIR203B-S0 這款抗干擾抗白光的PIR熱釋電紅外傳感器是如何做到高靈敏度和優越信噪比的？
首先它是利用溫度變化的特征來探測紅外線的輻射，
其次他是采用雙元補償的方法抑制溫度變化產生的干擾，提高了傳感器的工作穩定性。
再者它采用阻容濾波電路、阻容選頻電路，增強了傳感器的電磁兼容性，使傳感器對射頻干擾（RFI）的抗擾度高，
所以這款產品應用廣泛，例如防盜報警器、感應門、自動燈具、智能玩具、安防監控攝像機等。

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.
