IR sensor is a simple electronic device that emits and detects IR radiation in order to find out certain objects/obstacles in its range. Some of its features are heat and motion sensing. The technology is ideal for applications requiring a long and narrow detection range. Its job is to inform the valve when to start or stop the water flow based on the presence and/or movement of objects or people.

Nowadays, Infrared technology has a wide variety of wireless applications mostly in object sensing and remote controls.

RAJEYN IR sensor widely used in automatic sanitary wares, including sensor faucet, sensor flushing system for urinal and toilet, automatic soap dispenser, auto shower, and so on.

The function of the IR sensor for different sensor sanitary wares:

Auto Faucet Sensor
An automatic faucet or tap (also hands-free faucet, touchless faucet, electronic faucet, motion-sensing faucet, sensor faucet, or infrared faucet) is a faucet equipped with a proximity sensor and mechanism that opens its valve to allow water to flow in response to the presence of a user’s hands in close proximity.

There is mainly two kinds of IR sensor in the application of the sensor faucet, that is the auto sensor and the wave-on sensor.
(1)Auto sensor: When your hands approach the sensing range, water comes out automatically, and water stop when your hands leave, suitable for the bathroom application.

(2)Wave-on sensor: Your hands wave one time in the sensing range, water comes out, and wave again, water stop, suitable for kitchen application.

Auto Urinal Flush Sensor
The urinal conducts TWICE flushing for every usage. When you stand in the sensing range for 2 seconds, the urinal will auto flush for 2s (before usage); 2s after the person leaves, the urinal will automatically flush for 6s.

Auto Toilet Flush Sensor
When a person stands in the sensing range for over 3 seconds, the indicator light in the infrared sensor flash once, and the toilet will auto flush 5 seconds every usage after the person leaves the sensing range in 1-2s.

Auto Soap Dispenser Sensor
When your hands are in the sensing range, the soap dispenser will automatically dispense soap for 1.5s. Default soap dispense time is 1.5s. Soap dispense time is adjustable by a remote controller.
