Compost Heap Temperature Monitor Kit with Arduino Uno
Compost Heap Temperature Monitor Kit with Arduino Uno — Build a Smart Farming Sensor in 2 Hours
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Compost health depends on internal temperature. Too cold, and decomposition stalls; too hot, and beneficial microbes die. With this kit, a young maker or aspiring farmer builds a real-time temperature monitor that displays readings on an LCD and alerts with LEDs when the compost is in the ideal range.
What You'll Build
You'll assemble a waterproof DS18B20 probe that sits inside a compost heap, wired to an Arduino Uno that processes temperature data and shows the current reading along with a trend (rising, steady, falling) on a 16x2 LCD. Three LEDs indicate whether the pile is cold (blue), optimal (green), or hot (red), turning composting into a visible science experiment that teaches environmental monitoring and circuit logic.
What You'll Learn
- How a digital temperature sensor (DS18B20) communicates over OneWire protocol.
- Wiring and calibrating an I2C LCD backpack to reduce pin usage.
- Programming Arduino to read sensor data, compute trends, and control LEDs based on thresholds.
- Practical application of electronics in agriculture and environmental monitoring.

Who This Kit Is For
This beginner-friendly kit is ideal for CBSE Class 11-12 students exploring agricultural science and IoT, B.Tech ECE/EEE first-year mini-projects, ATL Tinkering Lab trainers introducing sensor ecosystems, and young rural innovators building smart farming prototypes. It bridges textbook theory with hands-on composting practicals, making it a favourite at Smart India Hackathon warm-ups.
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?
The AI companion walks you through every step, and you can WhatsApp us for a human touch if needed.
Can I leave the probe permanently in the compost?
The DS18B20 probe is waterproof and designed for soil/compost, but the cable should be protected from shovels or rodents. Keep the Arduino unit indoors or in a dry enclosure.
How do I calibrate the temperature thresholds?
The AI companion provides ready code with thresholds pre-set for typical composting ranges (cold below 40°C, ideal 40–65°C, hot above 65°C). You can tweak them easily in the Arduino sketch.
Can I log data or connect to a smartphone?
This kit focuses on the standalone monitor. You can extend it with a data logging shield (sold separately) or connect an ESP8266 for WiFi; the AI companion can guide that upgrade.
DS18B20 probe in compost pile shows temperature trend on LCD. Ideal range indicator LEDs.
