“Monitor a remote system (battery, power usage and sensors) with this Arduino MKR FOX 1200-based, Sigfox-connected solution.
My garage has no mains electricity or WiFi and so I use an old car battery for power and LED lighting, I’d like to know when the battery is getting flat, or if the door is open without having to go out to the garage.
I’m sure many remote/agricultural buildings have similar problems where it’s not feasible to run a mains supply and so they rely on battery power, maybe for powering the electric fences, small low power pumps to keep a leak from flooding or simple occasional lighting.
This project provides a way to monitor the battery level and power usage, along with sensor inputs and provide switchable outputs as well as a 5v USB power socket.”
