During a motion event, the Event Out pin will go high. This pin is accessible on J1 connector pin 1. User
has the flexibility to connect this interrupt pin to either the nRF52840 or nRF9160 devices’ GPIO in the
AVT9152 module using the 6-pin rainbow jumper cable provided with the kit, Arduino UNO connectors and
jumper J7, J12, J13. Please refer to the AVT9152 Quick Start Guide for help.
Related to the PIR sensor is the motion event LED. When the AmbiMate senses motion, the motion event
LED will illuminate.
