This solution is an analog motion sensor that can detect motion from two meters away by using a passive infrared sensor (PIR) sensor. The sensor is connected to a bandpass filter using op amps (SLG88103) to condition and filter the signal. The amplified condition signal is connected to the analog pin of the MCU to determine the strength and distance of motion. The signal also connects to nano-powered comparators, forming a window comparison that can be used to wake up an MCU or system upon motion detection.

The solution can be powered from either the connecting MCU board or externally. The external regulator also supports powering the MCU and other connecting solutions. This solution supports the Quick-Connect IoT (QCIOT) ecosystem. Other solutions can be daisy-chained.
