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 […]

Pump Motor Timer Circuit Diagram with Dry Run Protection
In this post I have explained about a circuit which can be used to monitor and detect the presence of municipal water supply by operating a pump motor through an intermittent ON/OFF timer. The timer keeps the pump motor ON for 15 seconds, if water is not detected, the pump is switched OFF for the […]
Pressure Switch Water Pump Controller Circuit
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 […]
SMS Based Pump Controller with Automatic Dry Run Shut Off
In this post I will show how to construct a SMS based water pump controller with automatic shutdown of pump when no water flow through the pump is detected. We will also construct another much simpler automatic dry run preventer circuit without GSM in the next half of the article. What is Dry Run in […]
3 phase Solar Submersible Pump Inverter Circuit
In this post I have explained a simple 3 phase solar submersible pump inverter circuit which can be made by configuring a few ICs and a few power devices. The idea was requested by Mr. Lufono and Mr. Sami. Circuit Objectives and Requirements First of all i must say thanks to you and Mr. Lufono, […]
Two Pipe Water Pump Valve Controller Circuit
In this article I have explained how to control a two pipe submersible pump valve to ensure that the pipe bringing in the municipal water is always given the main preference to the bore-well water source. The circuit is also equipped with a tank overflow cut-off feature. The idea was requested by Mr. Prashant. Circuit […]
