I want to design mechanical system which controls water pump automatically by turning it ON/OFF relative to water tank level. please discuss if you’ve any idea. Thank you!
Could use Float sensor/ Water Level Sensor for level detection in the tank, and could control the water pump using microcontroller system
I have something like the product in the link below connected to a submersible pump to get water out of a small tank and into a nearby drain. No microcontroller though.
