I think this could be cool?

•

Use a low-cost infrared sensor (e.g., MLX90614) connected to a microcontroller to measure temperature at different points on a surface.

•

Write code to create a heat map of the surface, displaying the temperature distribution visually on a computer.

•

Test materials with different thermal properties (e.g., metal vs. plastic) and write about the physics of heat transfer.

•

You can make like cool images so it’s fun.

•

But it does cost a bit: ~£15-£20 for the sensor, you might be able to get your school to fund you?
