MOTION DETECTION USING PIR SENSOR - IJSDR

As long as PIR sensor does not detect motion in the detection area, light and fans are not function and the fan is depends on the room temperature. Once the sensor is triggered, system will have around 2 minutes to run the function. After 2 minutes and sensor does not detect any motion, light and fans will be switched OFF automatically. 2. PROPOSED SYSTEM Alarm based human motion detection is ...

Using PIR Sensors for Motion Detection – Upverter Blog

· Principle behind the motion detection using PIR sensor. [Source: Adafruit] PIR motion sensors usually come in a three-pin package with VDD, GROUND, and SIGNAL pins. The supply voltage typically ranges from 3 to 5 V, although it can reach as high as 12 V in some sensors. Although the sensor itself is essentially a pair of photodiodes and a transistor, the dome-shaped packaging for …
