I wish to create a wireless water level indicator for measuring the level of water in my sump and then making automatic changes to the motor switch to fill the water to the overhead tank. What are the tools required to do so. In the market online, I find very less wireless options available. The float sensors are all wired, and are quite expensive. Is there a DIY solution to this?
I think installing two electrodes with a powered battery, with an alert occurring in my smart phone ( or a similar alarming system) is the way to go. For this, I think I need to have a bluetooth installed in the provisional sensor. As for remote controlling the switch of the water motor, I think I have to somehow modify the available controller in the market which works for wired sensors. Any ideas how this could be done from scratch. I am a total beginner in this. Thanks beforehand.
