Powered by a CR2032 and using the WT51822-S4AT bluetooth module, this board turns the bluetooth module on when motion is detected via the AM312 PIR sensor. When not active the circuit draws about 10uA and 1.4mA when active. This allows for a beacon to operate for weeks off a single button cell battery.
