A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications.
When hands are placed in the basin, the energy emitted from the sensor will bounce back irregularly which triggers the dispensation of soap. [7] Modern sensors used in electronic faucets, electronic flush valves and electronic soap dispensers use Infrared light with wavelength in the range of 850 nm. The sensor employs an emitter and a collector.
A passive infrared detector mounted on circuit board (right), along with photoresistive detector for visible light (left). This is the type most commonly encountered in household motion sensing devices and is designed to turn on a light only when motion is detected and when the surrounding environment is sufficiently dark.

A hands-free faucet in Japan. 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.
A microvalve is a microscale valve, i.e. a microfluidic two-port component that regulates the flow between two fluidic ports. Microvalves are basic components in microfluidic devices, such as labs-on-a-chip, where they are used to control the fluidic transport.
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [2] Bolometers and microbolometers are based on changes in resistance.
Since acoustic sensors (i.e., passive hydrophones and active sonar) perform less effectively in shallow waters than in the open seas, there is a strong pressure to develop additional sensors. One family of techniques, which will require electro-optical sensors to detect, is bioluminescence: light generated by the movement of a vessel through ...
