Soil Temperature Monitor Kit with DS18B20 & Arduino Uno - Plant Care
Plant Soil Temperature Monitor Kit with Arduino Uno & DS18B20 - Learn 1-Wire Protocol
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Whether you're tending a home garden, a school greenhouse, or a smart agriculture project, this kit lets you build a precise digital thermometer that measures soil temperature and displays it on a crisp OLED screen. The DS18B20 probe goes directly into the dirt, sending real-time readings to an Arduino Uno - and you'll learn the 1-wire communication protocol that makes it all work.
What You'll Build
A self-contained soil temperature monitor that shows current temperature in Celsius on a 0.96-inch OLED display, powered by a 9V battery. Perfect for tracking root-zone conditions in potted plants, hydroponics trays, or outdoor garden beds.
What You'll Learn
- How 1-wire digital communication works - connect multiple sensors on a single data line
- Interfacing an I2C OLED display with Arduino Uno
- Reading and calibrating DS18B20 temperature sensors
- Building a portable, battery-operated data-acquisition system

Who This Kit Is For
Perfect for CBSE Class 11-12 electronics students, ATL Tinkering Lab members, and B.Tech ECE/EEE first-years exploring embedded systems. Also a great DIY science project for class 8-10 or a quick prototype for Smart India Hackathon agriculture themes.
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 accessible via the QR code on the box can walk you through each step, from wiring the DS18B20 to uploading the code. If you prefer human help, WhatsApp support is available.
Can I use this to monitor water temperature instead of soil?
Yes, the DS18B20 probe is waterproof and works in water or air. Just seal the connection if immersing for long periods.
How accurate is the DS18B20?
It offers �0.5�C accuracy from -10�C to +85�C, ideal for plant soil monitoring.
Does this kit need soldering?
No, everything connects on a breadboard with jumper wires. No soldering required.
Industrial Process - DS18B20 probe in soil shows temperature for plant care on an OLED. Teaches 1-wire protocol.
