Plant Soil Temperature Monitor Kit with Arduino Uno + DS18B20 - Perfect Growing Conditions

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Most plants send silent signals when soil temperature strays from their comfort zone-growth stalls, roots stress, and blooms drop. This kit puts you in tune with that hidden world. You will insert the waterproof DS18B20 probe directly into potting soil, wire it to an Arduino Uno using the efficient 1-wire protocol, and display real-time temperature on a crisp OLED screen. The result is a handheld meter that tells you exactly when to water, shade, or bring plants indoors before a cold snap.

What You'll Build

You will assemble a portable soil temperature monitoring station that runs on a 9V battery. Once calibrated, it reads ground temperature within �0.5�C and updates every second. Use it to check seed-starting trays, raised beds, or even the compost pile. The OLED shows both current temperature and simple status icons you program yourself. This isn't a one-time demo; the finished device becomes a practical tool you'll reach for every gardening season.

What You'll Learn

• How to interface a DS18B20 sensor using the 1-wire protocol-only one data pin for power and communication
• Writing Arduino code to read digital temperature data and control an SSD1306 OLED display
• Using pull-up resistors to stabilise sensor signals on a breadboard
• Troubleshooting real sensor data, managing measurement intervals, and converting Celsius to Fahrenheit in code

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for young learners and curious gardeners. CBSE Class 11-12 students use it for physics and computer science projects, while B.Tech ECE/EEE students explore sensor integration. ATL Tinkering Labs adopt it as a ready-to-use agriculture-automation starter. Even home gardeners with zero coding experience succeed with our AI companion-no prior embedded systems knowledge needed.

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.
