How does China touchless motion activated sensor faucet work?
A touchless faucet is a magic faucet. It really is a technological marvel. You will be amazed when you know how touchless faucets work. Automatic kitchen faucets or touchless faucets are convenient and enhance hygiene. Read on for more details on touchless faucets. What is a touchless faucet? Touchless faucets use active infrared sensor technology that allows you to initiate water flow without touching the faucet. Instead, just put your hand in front of the sensor to start the water flow, and when you remove your hand, the water will stop. What's even more exciting is that most touchless faucets are designed to be sleek and elegant, and fit in any vanity, sink or restroom, from classic to modern. 5 parts of an touchless sensor motion faucet Touchless faucets use active infrared sensor technology that allows you to initiate water flow without touching the faucet.

Sensor Unit As the most important part, the sensor's job is to relay the signal to the valve to open the faucet when it detects your hand. Its job is to tell the valve when to start or stop flow, depending on the presence or absence of the hand. It has infrared or ultrasonic sensors. In most cases, the infrared sensor is usually placed on top of the spout. So what about infrared light and ultrasonic field sensors? When your hand is close to the spout, infrared light is reflected to the infrared detector. The valve will immediately receive a positive signal to open the faucet. in ultrasonic field sensors. When your hand moves to interfere with the sensor, water flows from the faucet. In the same way, when you lift the blockade, the flow stops. Active infrared non-contact sensors use the emission and reception of infrared beams to detect the presence and/or movement of objects or people within their detection area. This technology is ideal for applications that require long, narrow detection ranges. A microwave sensor or Doppler sensor detects motion within its detection range by the frequency of the electromagnetic microwaves it emits. Even if the sensors are behind solid materials, they can detect from several meters away. However, infrared sensor touchless faucets are the most common type on the market. 2. Solenoid Valve The positive or negative signal from the sensor controls the solenoid valve. The polarity of the signal determines whether the solenoid will perform a pull or push action. These valves control the flow of water by using a rubber-like disc. When there is no signal, the valve closes, which means no water is flowing through the faucet. If there is a hand, a positive signal will be sent to the solenoid, causing it to pull the valve, causing the water to flow open. When the hand is out, the...
