WebFeb 13, 2024 · 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. WebA PIR sensor is a type of motion sensor that detects the presence of a person or object by measuring the infrared radiation emitted by them. When the sensor detects motion, it triggers the light to turn on. This means that the light is only on when it is needed, saving energy and prolonging the life of the battery. carespot urgent care of orange park
