Wireless Water level Controller

[Annies]

There are more products online, but they are expensive and the low cost product may work for some months and then it get stucked. I have thought this one to build in the past, but haven't yet started.

Try on Amazon or flip-kart to see if the product is good or not.

Btw this device frequency and output is as per Indian laws of telemetry they are sell on amazon?
