PIR Motion Sensor: How to Use PIRs w/ Arduino & Raspberry ...

For proper calibration, there should not be any movement in front of the PIR sensor for up to 15 seconds (until pin 13 is turned off). After this period, the sensor has a snapshot of its viewing area and it can detect movements. When the PIR sensor detects a movement, the output will be HIGH, otherwise, it will be LOW. Using a PIR Sensor with Raspberry Pi. Circuit. Code. import sys ...
