Passive Infrared Sensors /PIR Sensors Applications

PIR sensors in lighting controls can detect a human body’s presence and automatically turn on the room’s lights. With a PIR lighting control, you do not need to operate the light switch manually. These lighting controls usually have a blank screen above the light switch. PIR sensors create an excellent energy-saving solution. It does this by eliminating wastes that can occur when people ...

What is an IR sensor? | FierceElectronics

2019-07-29· PIR sensors are most commonly used in motion-based detection, such as in-home security systems. When a moving object that generates infrared radiation enters the sensing range of the detector, the difference in IR levels between the two pyroelectric elements is measured. The sensor then sends an electronic signal to an ...

PIR Motion Sensor - Adafruit Industries

2020-01-25· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.
