The RAD2 (Research Activity Detector version 2) is a Feather compatible wing for sensing and logging motion. It includes a built in low-power passive infrared (PIR) sensor, a microSD card slot for logging data, and real time clock (RTC) for accurate timestamping. It also has 2 digital pins (A1 and A2) broken out to screw terminals for convenience and three signal LEDS for feedback.
The goals of this device are to:
- Monitor motion via a PIR
- Keep accurate time
- Enable easy synchronization of additional datastreams with motion data
- Log data locally but enable wireless transmission
- Battery life of >1 month
This shield is an adaptation/improvement of the original Rodent Activity Detector (RAD), adding a battery backed-up RTC, a built in PIR sensor, and a smaller form factor. It is now compatible with the Adafruit Feather ecosystem for easily adding motion sensing and datalogging to their entire range of boards. RAD2 was designed by MCCI and Lex Kravitz.
