Automated Composting Turner Kit with Arduino Uno + Motor
Automated Composting Turner Kit — Automate Organic Waste Decomposition with Arduino
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Instead of manually turning your compost pile or guessing when the microbial engine stalls, this kit lets you build a sensor-driven system that does it for you. Using a four-point DS18B20 temperature probe array, an Arduino Uno reads the compost core in real time, and when the temperature drops below the active decomposition threshold, it triggers a DC motor to turn and aerate the heap. Perfect for agriculture and sustainability projects, this kit turns a passive pile into an intelligent, self-regulating process.
What You'll Build
You will assemble a weather-resistant probe array that monitors four positions inside the compost pile, wire an Arduino Uno as the brain, and connect a motor driver and 12V DC motor to physically turn the mass. A real-time clock and microSD module log every temperature reading and motor activation, while a crisp 0.96‑inch OLED shows live status. The entire circuit is soldered onto prototype boards, ready for field testing.
What You'll Learn
- Interfacing multiple DS18B20 sensors on a single OneWire bus and reading precise temperature data
- Controlling DC motor speed and direction via L298N H‑bridge driver and Arduino PWM
- Logging sensor data with accurate timestamps using a DS3231 RTC and microSD module
- Soldering and assembling a robust circuit on prototype PCBs for real‑world deployment

Who This Kit Is For
Designed for B.Tech ECE/EEE and agricultural engineering students building smart farming projects, Smart India Hackathon teams needing reliable automation, and tinkerers at ATL Tinkering Labs or makerspaces. Whether you are prototyping for a college semester assignment or exploring precision agriculture at an IIT/NIT/VIT/BITS campus, this kit gives you a complete, hands‑on learning platform.
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 the box to launch the AI build companion specific to this kit. It walks through every connection, code snippet, and test. For additional help, WhatsApp message support is included.
Do I need prior soldering experience?
Basic soldering is helpful, but the included prototyping board and step‑by‑step guide make it manageable for a first‑time builder. The soldering iron and solder wire are in the box.
Can the probes survive long‑term in a moist compost pile?
The DS18B20 probes are waterproof, but for continuous outdoor use we recommend sealing the connection points with heat‑shrink tubing or silicone. The kit’s build instructions cover this.
How do I set the temperature threshold for turning?
The AI companion provides a ready‑to‑upload Arduino sketch. The threshold value is clearly marked in the code and can be changed with a single variable edit via the Arduino IDE.
DS18B20 array detects when compost core temperature drops below active decomposition threshold and triggers turner motor.
