Build a Wearable Fever Alert Badge with Arduino Nano & MLX90614 IR Sensor

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

Create a badge that watches your wrist temperature silently—no buttons, no wires dangling. This kit transforms an Arduino Nano and an MLX90614 infrared thermometer into a wearable health monitor. Perfect for school science fairs, everyday health checks, or simply learning how contactless sensing works in a friendly, hands-on way.

What You'll Build

You'll assemble a lightweight, clip-on badge that continuously reads skin temperature from the underside of your wrist. When the reading stays above 37.5°C, a pair of red LEDs lights up to give a clear fever warning. Green LEDs glow when temperature is normal. The whole circuit fits on a 400-point breadboard, and you can attach it to your sleeve or backpack with a safety pin, making health monitoring visible and simple.

What You'll Learn

• How infrared thermometry works and how to calibrate an MLX90614 sensor
• Reading I2C sensor data with Arduino and converting it to human-readable temperature
• Designing a visual alert system using threshold logic and dual-colour LEDs
• Building a wearable circuit on a breadboard and managing power with a 9V battery
