What is PIR sensor

PIR switch is an automatic control switch based on infrared induction technology. It realizes its automatic control function by sensing the infrared heat emitted from the outside. It can quickly open lamps, automatic doors, anti-theft alarms and other electrical equipment.

Why Purchase PIR Sensor

Principle of PIR detector

Infrared sensing switch is an automatic control switch based on passive infrared sensing technology. The main sensing device is human pyroelectric infrared sensor. The body temperature is generally 37 degrees, which will emit infrared with a wavelength of about 10 microns, while the temperature around the human body is generally lower than 37 degrees, which is greater than the infrared radiation wavelength of the human body. The pyroelectric infrared sensor works by detecting the changes of infrared radiation in the area.

Advantages of motion sensor light switch

Generally, it is mainly used for automatic control of street lamp switch in public places. The switch is composed of infrared detection circuit, infrared signal processing circuit, signal output control switch circuit and power supply circuit; The infrared signal processing integration mainly completes the infrared signal processing. The power supply of the circuit separately supplies power to each sub circuit in the design circuit according to the requirements of each part of the circuit, so as to ensure the stable performance of the circuit. The infrared induction switch has the advantages of long detection distance, wide application range, strong anti-interference ability and stable working performance.
