Build a Smart Water Tank Monitor with Arduino & Ultrasonic Sensor Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine never losing a crop again due to unnoticed low water in your hydroponic reservoir. This kit lets you build a real-time tank level monitor that lights up an LED bar as the water fills and sounds a buzzer when it’s critically low. It’s a perfect first step into precision agriculture for your school science exhibition or B.Tech agri-tech project.

What You'll Build

You’ll finish with a working water level indicator that reads the height of water in a tank using an ultrasonic sensor, displays the fill percentage on a 5-LED bar graph, and alerts you with a loud buzzer when levels drop below a preset threshold. The entire circuit sits neatly on a breadboard, and you can scale it to any tank size by tweaking the code.

What You'll Learn

• How an ultrasonic sensor works and how to interface it with Arduino
• Mapping sensor readings to water level percentages
• Controlling multiple LEDs and a buzzer via digital pins
• Writing conditional logic to trigger alerts for low water
