Automatic Ultrasonic Water Pump Motor Controller Circuit

Last Updated on May 14, 2026 by Swagatam 31 Comments

Transmitter

This project explains how to build a fully automatic ultrasonic water level controller where the water pump motor starts automatically when the tank level goes below a preset LOW level and stops automatically when the tank becomes FULL. The whole system is wireless, reliable, and there are no corrosion problems because the ultrasonic sensor never […]

Tap Water Induction Heater Circuit

Last Updated on May 5, 2021 by Swagatam 55 Comments

tap water induction heater compressed

A tap water heater circuit can be simply built by attaching an iron tube on the mouth of the tap or the faucet, and allow the iron pipe to pass through an induction heater coil. The induction heater will heat up the iron pipe and hence water passing through the the pipe will also heat […]

Pressure Switch Water Pump Controller Circuit

Last Updated on February 18, 2020 by Swagatam 17 Comments

pump

A pressure switch is a device which can be used for detecting water pressure in a tank and operate a water pump motor when the pressure gets too low, or the water in the tank goes lower than a desired minimum level. In this post I have explained a water pressure controller circuit for maintaining […]
