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 […]

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 […]
6 Best Ultrasonic Circuit Projects for Hobbyists and Engineers
In this post I have explained a 6 very useful yet simple ultrasonic transmitter and receiver circuit projects which can used for many crucial applications, such as ultrasonic remote control, burglar alarms, electronic door locks, and for listening to frequencies in the ultrasonic range which are normally inaudible to human ears. Introduction Many commercial ultrasonic […]
Ultrasonic Fuel Level Indicator Circuit
An electronic device or circuit which detects and indicates the various fuel levels in a fuel tank without a physical contact, through ultrasonic waves, is called an ultrasonic fuel level sensor In this post I have explained how to build a simple fuel tank level indicator circuit using Arduino and ultrasonic sensors. In every vehicle […]
Ultrasonic Distance Meter Circuit Using 16×2 LCD
In this article I will show how to construct an ultrasonic distance meter circuit using Arduino and 16×2 LCD. We are also going to see what an ultrasonic module is, how it works and how it can be used to measure distance. What is ultrasonic? An average healthy human being can hear frequencies ranging from […]
Ultrasonic Smart Automatic ON/OFF Switch Circuit
In this article we are going to build a smart automatic ON/OFF switch using Arduino, which can turn on or off gadgets automatically by sensing the presence of human nearby through the concept of ultrasonic. We are going to use ultrasonic module and Arduino to sense the presence of human which activates the gadgets such […]
