// PIR motion sensor connected to D3 (INT1)
|

// When RISE happens on D3, the sketch transmits a "MOTION" msg to receiver Moteino and goes back to sleep
|

// In sleep mode, Moteino + PIR motion sensor use about ~60uA
|

// With Panasonic PIRs it's possible to use only around ~9uA, see guide link above for details
