Map Temperature Gradients in Your Compost Pile — Vermicompost Temperature Map Kit with Arduino Uno and OLED

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

Vermicomposting works best when the pile stays between 20°C and 30°C — too hot and the worms die, too cold and decomposition stalls. This kit lets you see the temperature at three different depths side-by-side on an OLED screen, so you know exactly when to turn the pile or add moisture. Built around an Arduino Uno and three waterproof DS18B20 probes on the same 1-Wire bus, the system updates every second and can stamp readings with time using the included DS3231 real-time clock. It’s a field-ready tool for anyone serious about organic waste recycling, and a fantastic hands-on project for agriculture-focused STEM students.

What You'll Build

You’ll assemble a compact monitoring station that reads subsurface temperatures at three distinct compost depths, displays the vertical gradient on a 0.96-inch OLED screen, and logs the time of each reading. Everything plugs into a breadboard — no soldering. Once built, you can seal the electronics in a box and place the probes directly into a working vermicompost bin, vermi-bed, or even a regular compost pile to capture real thermal profiles that tell you whether microbial activity is optimal.

What You'll Learn

• Wiring and addressing multiple DS18B20 digital temperature sensors on a single 1-Wire bus
• Displaying real-time sensor data on an I2C OLED screen with custom layouts
• Using a DS3231 RTC module to timestamp readings for later crop or soil health analysis
• Interpreting temperature gradients in organic decomposition systems and connecting sensor data to vermiculture best practices

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit is ideal for CBSE Class 11–12 students taking up agriculture or electronics projects, B.Tech ECE/Agriculture Engineering undergraduates prototyping for Smart India Hackathon, and ATL Tinkering Lab mentors looking for a real-world sensor application. It also fits neatly into college-level coursework at NIT, VIT, BITS Pilani, or state universities where IoT and precision farming are emerging focus areas. If you already have basic Arduino experience and want to move from single-sensor demos to a multi-point data system, this is your next step.

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.
