Classification of sensor switches

1. Human body induction switch: It is an automatic control product based on infrared technology. When someone enters the sensing range, the dedicated sensor detects the change in the infrared spectrum of the human body and will automatically switch on the load. If the person does not leave the sensing range, the load will continue to be connected. Pass; when the person leaves, the load will be turned off automatically after a delay. When people arrive, the lights are on, and when people leave, the lights are off. It is cordial and convenient, safe and energy-saving, and shows humanized care.

2. Infrared sensor switch: usually mainly used for automatic control of street light switches in public places. The switch is composed of infrared detection circuit, infrared signal processing circuit, signal output control switch circuit, and power supply circuit; infrared signal processing integration mainly completes infrared For signal processing, the power supply of the circuit separates and supplies power to each sub-circuit in the design circuit according to the requirements of each part of the circuit to ensure the stable performance of the circuit. The infrared sensor switch has a long detection distance, a wide range of applications, strong anti-interference ability, and working performance. The advantages of stability.
