Water Level Visual Gauge Kit with Arduino Uno — Real-Time On-Screen Tank Monitoring

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

Ever wondered how to check your water tank level without climbing a ladder? This kit answers that question by turning an ultrasonic sensor into a visual gauge that displays the exact percentage inside a tank — all on a crisp OLED screen. You’ll build the whole system from scratch with an Arduino Uno, learning how to map real-world measurements to on-screen graphics. It’s a hands-on way to understand sensor data, mapping, and visual feedback for monitoring tanks, aquariums, or school science models.

What You’ll Build

You’ll wire an HC-SR04 ultrasonic sensor and a 0.96-inch I2C OLED display to an Arduino Uno, then upload code that measures distance and maps it to tank depth. The resulting on-screen gauge fills up in green for safe levels, shifts to yellow when it’s half‑empty, and turns red when almost empty — giving instant, at-a-glance status. The prototype is a complete, working tool you can demonstrate in ATL labs, CBSE fairs, or at home.

What You’ll Learn

• Interface an HC-SR04 ultrasonic sensor and read distance measurements
• Convert distance readings into tank fill percentage using a mapping formula
• Program the SSD1306 OLED to render a dynamic fill-bar and percentage text
• Implement colour thresholds (green, yellow, red) to indicate water level status
