DS18B20 Waterproof Temperature Sensor Starter Kit with Arduino Uno – Read Water and Soil Temperatures on a Live LCD

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

Imagine dipping a sensor into a glass of water or pushing it into garden soil and watching the exact temperature appear on a bright LCD screen seconds later. That is what you build with this DS18B20 starter kit — a practical digital thermometer that teaches one-wire communication, sensor reading, and display integration in a single afternoon. Whether you want to monitor an aquarium, test soil warmth for a science exhibition, or simply understand how temperature sensors talk to an Arduino, this kit puts a fully functional tool in your hands.

What You'll Build

You will assemble a working temperature monitoring station around the waterproof DS18B20 probe. The sensor sends readings through a single digital pin to an Arduino Uno, which then displays the Celsius value on a crisp 16x2 LCD. The circuit stays neat because the LCD uses an I2C backpack that needs only four wires. Once finished, you have a portable, battery-powered instrument that you can take to a farm, a pond, or your kitchen — and the AI companion will help you extend the code to log data or set alerts.

What You'll Learn

• How one-wire digital sensors like the DS18B20 send temperature data without analog calibration
• Wiring and coding an I2C LCD module to show real-time sensor values
• Using a breadboard to prototype a clean circuit with pull-up resistors and power management
• Adapting the core project for soil moisture, water level, or multi-sensor setups

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit fits perfectly into CBSE Class 11-12 physics and computer science projects, B.Tech ECE/EEE sensor labs, and ATL Tinkering Lab challenges. Young learners aged 10 and above who are curious about environmental monitoring will find the assembly straightforward and the results immediately satisfying. Even first-time Arduino users from IIT, NIT, VIT, or BITS campuses get a complete, no-frustration introduction to digital sensing.

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.
