Build a Turbidity Monitor to Study Soil Erosion with Arduino – STEM 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.

When rain falls on bare soil, it carries sediment into streams. This kit lets you build a working turbidity monitor that shows exactly how much clearer the water becomes when plants cover the soil. Perfect for science fairs, CBSE practicals, and ATL Tinkering Labs, the project turns an Arduino Uno, a turbidity sensor, and a 16x2 LCD into a real-time water quality meter.

What You'll Build

You'll assemble a portable water-testing station that displays NTU (nephelometric turbidity units) on an LCD screen. Pour water samples from two erosion trays—one with plant cover, one without—and watch the sensor output change. The finished project fits in a shoebox, runs on a 9V battery, and can be demonstrated live in class.

What You'll Learn

• How to wire a turbidity sensor to Arduino and interpret its analog signal
• Coding and calibration to display meaningful NTU values on an I2C LCD
• Using a breadboard to prototype a sensor circuit without soldering
• Designing a controlled experiment to compare soil erosion under different conditions

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for CBSE Class 7–12 students exploring environmental science and electronics, B.Tech ECE/EEE first-year students doing mini projects, ATL Tinkering Lab facilitators running pollution-monitoring challenges, and hobbyists preparing for Smart India Hackathon environment tracks. If you've ever tried to explain soil conservation with charts, this hands-on tool makes the science tangible.

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.
