# Thermal Imaging Camera with Raspberry Pi

**Difficulty:** Intermediate | **Estimated Time:** 3 hours

Build a handheld thermal imaging camera using an IR sensor array and a Raspberry Pi with display.

### Overview

This project combines a thermal imaging sensor with a Raspberry Pi to create a portable thermal camera. Visualize heat signatures in real-time with a colour-mapped display.

### What You Will Learn

- Working with thermal (LWIR) sensor arrays
- Processing and interpolating thermal image data
- Creating real-time colour-mapped visualizations with Python
- Building a complete embedded device

### Step 1: Connect the Sensor

The IR thermal imaging module connects via I2C to the Raspberry Pi. Wire SDA, SCL, 3.3V and GND. The MLX90640 sensor provides an 80x62 pixel thermal array.

### Step 2: Install Dependencies

1. Install the adafruit-circuitpython-mlx90640 library
2. Install numpy and pygame for visualization
3. Enable I2C and set the baud rate to 1MHz for faster frame rates

### Step 3: Build the Viewer

Write a Python script that reads the 80x62 thermal array, interpolates it to a higher resolution, applies a colour map (e.g. ironbow), and displays it on screen. Add temperature readout at the cursor position.

### Step 4: Optional Enhancements

Add image capture (save thermal snapshots), temperature logging, or even a 3D-printed enclosure to make it truly portable.
