PIR Motion Sensor - Adafruit Industries

Jan 25, 2020· When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected. The PIR Sensor

Tutorial: How to use the HC-SR505 PIR sensor with the ...

Aug 30, 2017· PIR (Pyroelectric InfraRed) sensors measure infrared (IR) light that is radiating from objects in the detection area. The HC-SR505 is such a sensor. It very easy-to-use as it already delivers a HIGH signal if something is moving in the detection area. This HIGH signal lasts about 8 seconds, which is sometimes seen as a disadvantage. Unfortunately, […]
