...Back to Projects:
Low power PIR sensors can be tricky to get right - here's a way to get a push notification any time motion is detected within a room. Since the trigBoard uses less than 1uA of standby current, we need to find a PIR sensor that uses very little current, especially because these sensors need to be "always on". I found one that pulls 10-12uA, so this is a perfect fit for this... plus they're pretty inexpensive. That amount current is still pretty low, so with a 1000mAh battery or so, you can expect very long battery life.
Parts needed
- PIR Sensor based on the AM312: https://www.amazon.com/gp/product/B07GJDJV63/ref=ppx_yo_dt_b_asin_title_o00__o00_s00?ie=UTF8&psc=1
- 10uF capacitor - any would work that you have lying around.
- trigBoard & battery
Installation
trigBoard setup
- Cut the top "NC" jumpers as well as the small trace under above the jumper to the right. Also, fill in the bottom "NO" jumpers with solder:
