Wireless water level controller with auto on off

[pgr2002]

Can any one suggest a suitable circuit to pump water from ground sump to overhead tank that also wireless with rxtx modules to keep it compact. The receiver will control pump via relay to cut off when level is almost full. The transmitter will guage the water level in the overhead tank and respond accordingly.

And also the transmitter may be fitted with a solar module to charge the chargeable battery

Hi,

A rough sketch could be one of those two-wire water level sensors connected to the tx half of a duo of ICs that seem used loads for functions like yours but whose names I can't remember nor Googling, someone else hopefully knows the ones I mean (I think H something or other?). I'll bet Adafruit sell such a kit, for example.

Maybe a transistor between the rx output and the relay coil, and flyback diode.

Hi,

Why wireless?
What distance?

Klaus

Distance from overhead tank to ground level will be approx. 35ft.
