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 […]

GSM Car Ignition and Central Lock Circuit Using Arduino
In this post I will show how to construct a GSM based car security system using Arduino, which can lock and unlock car’s ignition system and central lock by sending a password SMS to car from your cellphone Car theft can be a heart break; it feels like your loved one got kidnapped. It hurts […]
Car Reverse Parking Sensor Circuit with Alarm
In this post I will show how to construct a car reverse parking sensor alarm circuit using arduino, ultrasonic sensor and 2.4 GHz transceiver module. This project can be add-on feature for your car if it doesn’t sport a build-in parking sensors. Introduction The proposed project has similar functionality as traditional car parking sensor has, […]
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 […]
Incubator Using Arduino with Automatic Temperature and Humidity control
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 […]
Automatic Street Light Dimmer Circuit
In this post I will show how to construct an Arduino automatic street light dimmer circuit, which can reduce its brightness when no vehicle is passing in the road to save power. Overview We will be exploring the methodology of sensing the vehicle or human being without false detection which may occur due to animals […]
