Compost Heat Monitor Kit with Arduino Uno + LED
Track Microbial Heat: Compost Monitor Kit with Arduino Uno & OLED Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your compost pile into a live science experiment. Watch the temperature climb on the OLED screen as billions of bacteria break down organic matter. This kit transforms the invisible process of decomposition into real-time data you can log and analyse, perfect for school biology or STEM fairs.
What You'll Build
A portable temperature monitor that you bury into your compost heap, reading from a waterproof DS18B20 probe. The 0.96-inch OLED display shows current temperature and a running log with timestamps, thanks to the DS3231 real-time clock. You’ll have a working data logger that demonstrates the thermophilic phase of composting in any biology class.
What You'll Learn
- Connect a 1-Wire digital temperature sensor to an Arduino Uno
- Display real-time sensor readings on an OLED screen
- Use a real-time clock module to timestamp each measurement
- Understand how microbial activity generates heat during composting

Who This Kit Is For
Perfect for CBSE students (Class 6–10) combining biology with coding, ATL Tinkering Lab projects on environmental monitoring, and Smart India Hackathon junior challenges. Also a great starter kit for B.Tech ECE/EEE students learning Arduino and sensor integration in their 1st‑year mini‑projects.
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.
What if I get stuck during the build?
Scan the QR code inside the box to chat with our AI build companion, trained on this exact kit. If you need human help, you can message us on WhatsApp for guidance within hours.
Can I leave the DS18B20 probe buried in wet compost?
Yes, the sensor is fully waterproof and rated for long‑term immersion. Just make sure the cable connection stays dry by routing it out of the compost.
How long can the temperature logger run on a 9V battery?
With a fresh 9V alkaline battery, the kit can log temperatures for up to 8 hours continuously. For longer logging, simply connect a USB power bank to the Arduino instead.
What composting science can I observe with this kit?
You'll see the classic temperature curve: a rapid rise as mesophilic then thermophilic bacteria become active, peaking around 55–70°C, followed by a gradual decline. This mirrors industrial composting and teaches real‑world microbiology.
DS18B20 probe in compost shows temperature rise from bacterial decomposition activity.
