There are all sorts of handy tools out there, and a handful of them can be made from scratch with a Raspberry Pi. No one knows this better than maker and developer Arnov Sharma who’s using our favorite SBC to power this custom-built temperature gun. To save on power, he’s opted to use the latest Raspberry Pi Pico 2 microcontroller.

According to Sharma, he wanted to create an open source temperature gun that anyone could recreate on their own. This device lets you monitor temperature without making contact with the help of an infrared temperature sensor. The module used to pull this off is known as a G7-906 which can interface easily with the Pico 2.
Sharma explained that this is the first version of the project and is more of a prototype that proves its function. As such, it’s built around a breadboard — but another version is planned that will include a custom PCB and completely soldered connections. That said, this prototype proves that you don’t need the custom PCB to make the project work.
