The infrared sensor is an automatic control product based on infrared technology. When someone enters the sensing range, the dedicated sensor detects the change of the infrared spectrum of the human body and automatically connects to the load. If the person does not leave the sensing range, it will continue to be connected; after the person leaves, the delay The load is automatically turned off when The lights are on when people arrive, and the lights are off when people leave. It is cordial and convenient, safe and energy-saving, and shows humane care. In the fields of medicine, military science and environmental engineering, infrared sensors are widely used.

Infrared sensor introduction

The infrared sensor is developed based on the principle of infrared reflection and is a kind of intelligent water-saving and energy-saving equipment. Including sensor faucet, automatic hand dryer, medical hand washing device, automatic soap dispenser, sensor flushing device, this is the standard name,

There are also called thermal infrared human sensors.

Principle of infrared sensor

     This is based on the principle of infrared reflection. When the human hand or a certain part of the body is in the infrared region, the infrared light emitted by the infrared transmitting tube is reflected to the infrared receiving tube due to the human hand or body block, and processed by the microcomputer in the integrated circuit The signal is sent to the pulse solenoid valve. After receiving the signal, the solenoid valve opens the spool according to the specified instruction to control the head water; when the human hand or body leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve spool passes through the internal spring Turn off the water controlled by reset.
