I was thinking there must be a simple sensor that could tell me when the water level has fallen a set amount and automatically run the "fill pool" zone on the Rachio.

I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...

Check out the new water level sensor circuit. The simple water level indicator circuit presented here makes this system automatic, i.e. it switches on the pump when the water level in the overhead ...

Researchers at the University of Bonn have developed a method that allows the water level of rivers to be monitored around the clock. The cost-effective sensor is for instance suitable for area ...
