A new video published on the do-it-yourself YouTube page Blitz City DIY provides step-by-step instructions on how to build a thermalcamera using components that—in total—will cost just over $150 (USD).
The camera is based on three hardware components, starting with a Raspberry Pi 3 Model B single board computer, which features a Quad Core 1.2GHz BCM2837 CPU, four USB 2.0 ports, CSI camera port for connecting a Raspberry Pi camera, DSI display port for connecting a Raspberry Pi touchscreen display, and more. An Adafruit HDMI 4 Pi 5" Display, with touch and mini driver, was also used. This features an 800 x 480 resolution display and USB-enabled 40-pin to 50-pin touchscreen adapter board.
Finally, an Adafruit AMG8833 IR thermal camera breakout is used to capture images. The AMG8833 features an 8 x 8 Panasonic infrared detector that when connected to the Raspberry Pi, returns an array of 64 individual infrared temperature readings. The camera will measure temperatures ranging from 32°F to 176°F. Additionally, Liz from Blitz City DIY used a cell phone power bank she had to power the camera, as well as a picture frame onto which the camera project is tethered.
"The AMG8833 is an Adafruit product and they have a great learning guide on it, showing you how to use it with both Arduino and Raspberry Pi," she explained in her post on Hackster. "I chose to use a Raspberry Pi because in the example code provided by Adafruit, it uses bicubic interpolation to basically make the image appear to have a higher definition and not look as pixelated. I wanted to setup the AMG8833 with the Pi as a camera that had a screen on the back and was handheld, portable and not tethered to a wall for power."
She also remarked on the completion and usability of the camera: "Overall, I’m pretty excited with how this project came out. It’s definitely something I’m going to be using in the future because I do a lot of benchmarking and looking at things like thermal readings, so to have a visual representation I can get on camera to get an idea of how things are behaving will be really cool."
