What is the principle of induction faucet (induction faucet principle)

The principle of the induction faucet is that when a human hand is placed in the infrared area of the faucet, due to the obstruction of the human hand, the infrared emitted by the infrared emitting tube is reflected to the infrared receiving tube, and the microcomputer processes the signal and sends it to the electromagnetic valve, which opens the valve core to control the faucet to discharge water according to the specified instruction.

Functional characteristics of induction faucet:

1, intelligent power saving: low-power chip control, built-in power saving working mode, ultra-low energy consumption, more effective power saving.

2. Intelligent water-saving: put your hand into the sensing range of the faucet and immediately get out of the water, and turn off the water immediately after leaving.

3, convenient and sanitary: the water switch is completely automatically completed by the sensor, that is, when water is sensed, it comes out, hands in, hands out, water automatically stops without touching the faucet, effectively avoiding bacteria and cross infection; Avoid contact and use to prevent cross infection.

4, built-in filter screen, effective anti-blocking, easy to disassemble and easy to wash. The water switch is automatically completed by the sensor, and people do not need to touch the faucet, thus effectively avoiding cross infection of bacteria.

5. Overtime protection: If the continuous use time exceeds 1 minute, the machine will automatically turn off the water, so as to avoid the phenomenon that there is a foreign body in the sensing range for a long time, which causes long-term running water, wastes water resources and then releases water after sensing.

6. Automatic distance adjustment: The machine is controlled by a microcomputer, which can automatically set the optimal sensing range according to the color and shape of the basin without manual adjustment.

7. Weak current prompt: The battery voltage is lower than 4.6V, and the red indicator light flashes, prompting to replace the battery.

8. Optional power supply: there are AC, DC and AC -DC dual-purpose power supply modes, and the AC -DC dual-purpose mode can realize automatic soft switching.
