What is an IR sensor?
An infrared (IR) sensor is an electronic device that measures and detects infrared radiation in its surrounding environment. Infrared radiation was accidentally discovered by an astronomer named William Herchel in 1800. While measuring the temperature of each color of light (separated by a prism), he noticed that the temperature just beyond the red light was highest. IR is invisible to the human eye, as its wavelength is longer than that of visible light (though it is still on the same electromagnetic spectrum). Anything that emits heat (everything that has a temperature above around five degrees Kelvin) gives off infrared radiation.
There are two types of infrared sensors: active and passive. Active infrared sensors both emit and detect infrared radiation. Active IR sensors have two parts: a light emitting diode (LED) and a receiver. When an object comes close to the sensor, the infrared light from the LED reflects off of the object and is detected by the receiver. Active IR sensors act as proximity sensors, and they are commonly used in obstacle detection systems (such as in touchless faucets).
Active infrared sensors use the emission and reception of infrared beams to detect the presence and/or movement of objects or people in their field of detection. 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 flow based on the presence and/or movement of objects or people.
Rajeyn infrared sensors are widely used in automatic sanitary ware, such as touchless faucets, automatic urinal flusher and toilet flush valve.
The infrared sensor is widely used in public washrooms, such as touchless faucets, automatic urinal flusher, automatic toilet flusher and automatic soap dispenser. The infrared sensors can be also used for touchless kitchen faucets and bathroom faucets. Although they are still optional in homes today. But eventually in the future, they will become a simple commonality for modern homes.
The sensor eye RJY-IN01 is widely used for automatic commercial sensor basin faucets and automatic urinal flush valves. Sensor functions and wire connections can be tailor-made according to customer’s request.
Faucet Function: Automatic on/off. This is the regular function for touchfree basin water faucets. You put your hands on the sensor range, water automatically flows. You remove your hands out of the sensor range, water automatically stops. The water will automatically stop flowing if continuously flowing for 60 seconds (We call this function security stop timing and this timing can be customized).
Urinal Function: Pre-flush 2s and after flush 6s.The urinal conducts TWICE flushing for every usage. When a person stands in the sensing range for 2 seconds, the indicator light in infrared sensor flash once, the urinal will auto flush for 2s (before usage); 2s after the person leaves, the urinal will automatically flush for 6s. The urinal will automatically flush ONCE if no usage within 24hours.
Rajeyn Sensor Features and Applications
- Used for commercial and household touchless faucets/urinal flush valves etc.
- Adjustable sensor range and flushing time by a remote controller.
- Auto-save parameters if power failure.
- Low power consumption. 4AA alkaline batteries lasts about 2 years.

- We have more than 50 different sensor eyes and electrical wires for your selection.
- The automatic valve closing function of AC power-off can be widely used in intelligent bathroom products.
There are over 50 different sensor housings to suit different design PCBAs. They are variety of designs for all-in-one type and separated PCBA. Shapes including round, rectangle, semicircular etc. The sensor functions and wire connections can be tailor-made based on cc
Besides sensor cases, we have variety of waterproof wire connections. The most popular types are 4-pin waterproof wire connecting with control box for sensor taps and 2-pin as well as DC type waterproof wires for sensor urinal and sensor toilets. Below are some potting sensors with different sensor cases, PCBA and wires. We are capable of providing tailor-made infrared sensors for your automatic systems.
