AR6880 Faucet Sensor
The induction faucet is based on the infrared reflection principle. When the human hand is placed in the infrared area of the faucet, the infrared ray from the infrared transmitting tube is reflected to the infrared receiving tube due to the shield of the human hand, and the signal processed by the microcomputer in the integrated circuit is sent to the pulse solenoid valve. After the solenoid valve receives the signal, it opens the valve core according to the specified command to control the faucet Water: when the human body’s hand leaves the infrared sensing range, the solenoid valve does not receive a signal, and the solenoid valve core resets through the internal spring to control the water off of the faucet.
