Water Tank Level Monitor Kit with Arduino Uno + Ultrasonic v2 — Monitor Your Tank Without Climbing a Ladder

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

Stop guessing how much water is left in the overhead tank. This kit lets you build a small, battery-powered device that uses ultrasonic sound waves to measure the water level and shows it right on a bright screen. Read the distance in centimetres, inches, or feet—and press the button to freeze the last reading while you walk away from the tank. It’s a practical tool hidden inside a beginner-friendly electronics project, perfect for school assignments or everyday home use.

What You'll Build

You'll assemble a handheld or wall-mountable water level indicator that works just like the sensors used in real agricultural and industrial tanks. The HC-SR04 sends out a sonic pulse, catches the echo, and the Arduino calculates the distance to the water surface. The 0.96-inch OLED displays all three units at once, updated instantly. One tactile button locks the reading so you can read it later—ideal when the tank is in a dark or hard-to-reach corner. This is the kind of project that ATL Tinkering Lab students and CBSE Class 11-12 physics enthusiasts often use to demonstrate echo-ranging principles.

What You'll Learn

• Interface an HC-SR04 ultrasonic sensor with Arduino Uno and read precise distance values
• Drive a 0.96-inch OLED display using I2C and switch between centimetres, inches, and feet
• Use a tactile button as a freeze/hold input to lock the latest measurement on screen
• Assemble a working electronic system on a breadboard without any soldering

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you are a parent or teacher looking for a hands-on STEM activity that demonstrates physics and coding, this kit is a natural fit. It is widely used in ATL Tinkering Labs across India and aligns with CBSE Class 11-12 sensor-based practicals. First-time makers as young as 10 have completed it in a single weekend with the included AI guidance. Older beginners or B.Tech ECE students can use it as a quick mini-project prototype.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
