### AI overview

This article describes a DIY handheld thermal camera built with an Arduino UNO R4 Minima, a Seeed Studio MLX90640 thermal imaging sensor, and a DFRobot touchscreen. The board reads the sensor's 32x24 infrared data over I2C, processes it into an image, and displays it through a user interface in a 3D-printed enclosure.

### Source excerpt

Thermal cameras are really cool, because they give you the ability to clearly see something we humans usually can't: temperature. It is interesting to look at the world through that lens. Thermal cameras are also very useful when working with anything that involves heat, such as for spotting a leak in an HVAC system or [...] The post Building a DIY handheld thermal camera for work and play appeared first on Arduino Blog.
