Ultrasonic Fuel Level Indicator Circuit

Last Updated on May 16, 2026 by Swagatam 53 Comments

fuel installation

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 […]

Incubator Using Arduino with Automatic Temperature and Humidity control

Last Updated on May 16, 2026 by Swagatam 53 Comments

incubator layout

In this post I will show how to construct an incubator using Arduino which can self-regulate its temperature and humidity. This project was suggested by Mr. Imran yousaf who is an avid reader of this website. Introduction This project was designed as per the suggestions from Mr. Imran, but some additional modification is done to […]
