PIR Sensor Application in Induction switch, Induction Light

Pyroelectric Infrared Sensor use the MCU for communication, when the PIR sensor performs continuous motion sensing, the MCU does not need to be activated, it only activates the external MCU when motion is detected. Motion detection results are sent out via the output interrupt signal.The algorithm for motion detection is programmable and can be changed by external MCU configuration, The PIR signal is converted into a 14-bit digital value on the chip, and then enters the motion algorithm detection unit. All signal processing is digital and supports motion detection result output and raw data output.
