The proposed solar water heater with battery charger controller circuit explains a simple method of utilizing the excess solar energy from a solar panel for heating water in water tanks or swimming pools or poultry egg chambers. Normally the circuit also functions like an automatic solar battery charger, and simultaneously powers domestic electrical appliances. Understanding Solar Charging […]

Water/Coffee Dispenser Motor Circuit
In this article I have explained a protection circuit which may be used for preventing a “dry run” situation in mini coffee dispenser motor pumps, by sensing the slight difference in its wet and dry current consumption levels. The idea was requested by Mr. Ken Adler. Technical Specifications I read with great interest your post titled, […]
Automatic Ultrasonic Water Pump Motor Controller Circuit
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 […]
Simple Digital Water Flow Meter Circuit using Arduino
In this post I will show how to construct a digital water flow meter using Arduino and 16 x 2 LCD display. We will be taking a look at YF-S201 water flow sensor, its construction and working and how to interface with Arduino to extract some useful readings. The proposed project can measure the rate […]
Adding a Soft Start to Water Pump Motors – Reducing Relay Burning Problems
In this post I have explained a few innovating and simple soft start circuit examples which may be implemented with heavy duty motors so that they are able to initiate with a soft start or a slow sluggish start instead of a sudden, bumpy start Why Soft Start is Crucial for Heavy Motors When heavy […]
Ultrasonic Wireless Water Level Indicator – Solar Powered
An ultrasonic water level controller is a device which can detect water levels in a tank without a physical contact and send the data to a distant LED indicator in a wireless GSM mode. In this post I will show how to construct a ultrasonic based solar powered wireless water level indicator using Arduino in […]
