Build Your Own Non-Contact Infrared Pyrometer with Arduino Uno and MLX90614

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

Point, read, and instantly know the temperature — without ever touching the surface. This kit lets you build a handheld infrared pyrometer that uses the MLX90614 sensor to measure surface temperature from a 10 cm distance, displaying both target and ambient readings on a crisp OLED screen. Ideal for checking the heat of electronics, monitoring 3D printer hotends, or conducting physics experiments, this project turns you into a maker with a practical instrument.

What You'll Build

You'll assemble a working, portable non-contact thermometer that reads surface temperatures with an accuracy of ±0.5°C. The OLED instantly shows the object temperature and the surrounding ambient temperature. The entire circuit fits on a breadboard and is powered by a 9V battery, so you can carry it anywhere — from your workbench to the school lab. By the end, you'll have a tool that’s genuinely useful for troubleshooting hot components or demonstrating infrared physics.

What You'll Learn

• Interfacing the MLX90614 infrared temperature sensor via the I2C communication protocol
• Displaying real-time sensor data on a 0.96-inch OLED screen with crisp text and graphics
• Calibrating measurements for accurate non-contact readings and understanding emissivity
• Programming the Arduino Uno to process sensor data and control peripheral devices

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for CBSE Class 11–12 students undertaking physics practicals or investigatory projects, first-year B.Tech ECE/EEE mini-project builders, and participants in ATL Tinkering Lab challenges. It's also an exciting weekend build for hobbyists who want to add a contactless temperature sensor to their maker toolkit. The beginner-friendly instructions make it accessible even if you've never wired a sensor before.

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.
