I bought a wireless motion sensor (well, PIR) to cover the front door/porch area, so hopefully I'll know when the UPS/FedEx ninjas leave a package.
The receivers plug into AC outlets, but the sensor runs on 3 AAA batteries. I'm wondering if any of y'all have/had these and can give me an idea on battery life expectancy.
Thanks.
