Pretty sure the sensor detections motion above a threshold. So basically "the food bag was moved 45 degrees" is the trigger. That should kick off a 915Mhz analo

Pretty sure the sensor detections motion above a threshold. So basically "the food bag was moved 45 degrees" is the trigger. That should kick off a 915Mhz analog pulse. It's not a digital stack IIRC, which is why the battery is so small and circuit is like a dollar total.
