I’ve been playing around with a Spark Core, which is a small, cheap ($39) Wifi-enabled Arduino-compatible device. As a software guy, I don’t do much with hardware, but the Spark Core makes it really easy to get going.
Anyways, I was able to hook up a Grove Water Sensor to it, and have it mounted near my sump pump. If the pump would ever go out, the device will send me a text message (via Twilio) to alert me.
The whole setup is pretty simple, and I’ve put all the relevant firmware and software up on Github in case anyone else is interested in doing something similar. Total hardware cost was $42, and just $1/month for Twilio.
