Smart Compost Turner Kit with Arduino Uno + Motor
Smart Compost Turner Kit – Automate Compost Aeration with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your compost bin into a self-regulating ecosystem that actively prevents foul odors and accelerates decomposition. This advanced kit equips you to build an Arduino-driven system that reads compost temperature from an array of four DS18B20 probes and monitors CO2 levels using an MH-Z19B sensor. When early signs of anaerobic activity appear, the logic triggers a DC motor via an L298N driver to turn the pile automatically—no guesswork, no manual turning.
What You'll Build
You'll assemble a fully functional monitoring and aeration unit that mounts inside a compost bin. The 0.96-inch OLED displays real-time temperature and CO2 concentrations while the microSD module logs timestamped data through the DS3231 RTC. As soon as the compost indicates oxygen depletion, the motor engages to aerate, maintaining ideal conditions for microbial activity and drastically reducing the risk of methane buildup.
What You'll Learn
- Integrate multiple DS18B20 1-Wire temperature sensors on a single bus
- Read MH-Z19B CO2 concentrations using serial communication
- Write logic to trigger a DC motor via L298N driver based on sensor thresholds
- Log sensor data with precise timestamps using DS3231 RTC and microSD module

Who This Kit Is For
This advanced kit is designed for B.Tech ECE/EEE students tackling final-year projects, Smart India Hackathon participants prototyping sustainable solutions, and engineering undergraduates from IITs, NITs, VIT, or BITS campuses. It’s also perfect for tech-savvy home composting enthusiasts who have already built basic Arduino projects and now want to fuse multi-sensor data with real‑world actuator control.
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 on your kit box to chat with our AI companion, trained on every step of this Smart Compost Turner project. You can also WhatsApp our support team for human help.
Can I use this kit with a compost bin outdoors?
Yes, but you must protect the electronics from rain and direct sun. We recommend an IP65 enclosure (not included) for the microcontroller and sensors. The DS18B20 probes are waterproof.
How do I set the CO2 threshold for triggering the motor?
The AI companion provides a sample sketch with a threshold of 1000 ppm. You can adjust this value in the code based on your compost’s baseline readings. We recommend logging data for 24 hours first to find the right trigger.
Can I add Wi-Fi connectivity to monitor remotely?
Certainly. The Arduino Uno lacks built-in Wi-Fi, but you can add an ESP8266 module (not included) to send data to a dashboard. Our build companion includes optional code for this upgrade.
DS18B20 array and CO2 detect anaerobic conditions and trigger relay DC motor to aerate compost.
