The Mini PIR Sensor features a compact size board and can be mounted in a project through a hole in a case (only the PIR lens showing with all the electronics hidden inside the case). This makes it ideal in applications where users need to track movements with a small device or in projects that have to be sealed from high-humidity environments. The Mini PIR Sensor is a pyroelectric device, and it detects motion by sensing changes in the infrared levels emitted by surrounding objects. When motion is detected, the Mini PIR Sensor outputs a high signal on its output pin.
