Soil Temp Kit with Arduino Nano + DS18B20
Monitor Soil Temperature for Healthier Plants with the Soil Temp Kit – Arduino Nano & DS18B20
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Have you ever wondered if your plants are too cold or too warm underground? With this kit, young gardeners and curious makers build a digital thermometer probe that reads soil temperature in real time, displayed on a bright OLED screen. Perfect for science projects, terrace gardens, or understanding the hidden world beneath the soil, this build teaches the 1-wire protocol used in professional weather stations.
What You'll Build
You'll assemble a functional soil temperature monitoring system that plugs a waterproof DS18B20 probe into the ground and shows live readings on an OLED display. The code is simple enough for beginners to modify, turning the kit into a plant-care assistant that warns when soil gets too cold for sensitive crops. By the end, you’ll have a battery-powered gadget ready for any school science fair or garden experiment.
What You'll Learn
- Connect and read data from a digital temperature sensor using the 1-wire protocol.
- Display real-time values on an OLED screen using I2C communication.
- Program an Arduino Nano to act as a data logger and alert system.
- Troubleshoot basic electronics circuits on a breadboard – no soldering required.

Who This Kit Is For
Young explorers (age 8-15) participating in ATL Tinkering Labs or CBSE science exhibitions will find this an exciting introduction to environmental sensing. It’s also ideal for B.Tech ECE students preparing for Smart India Hackathon who want a simple weather station sub-system. Parents homeschooling in India love the guided, all-in-one approach that keeps kids engaged for hours without needing a soldering iron.
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?
Our AI companion, accessible via QR code, guides you step-by-step, with human backup on WhatsApp if needed.
Can I use this kit outdoors?
The DS18B20 probe is waterproof and can be left in soil, but the breadboard and Arduino should be protected from rain.
Does it work without a computer?
Once programmed, the Arduino runs off a 9V battery (not included) for portable field use.
What plants can I monitor?
The soil temperature range of the DS18B20 (-55°C to +125°C) covers all gardening scenarios; ideal for checking if soil is warm enough for seed germination.
DS18B20 probe in soil shows temperature for plant care on an OLED. Teaches 1-wire protocol.
