DIY Thermal Imager Creates a Real Life Heat Map Of Your Home

If you’re looking to get solid picture of where the poorly insulated and leaky parts of your home are, this DIY thermal imager maps the temperature over an actual photo.

It’s a really clever mashup of tools, frankly. Courtesy of, this project combines a thermal flashlight that uses a non-contact infrared thermometer with a digital camera. Darken the room, set the camera for a long exposure, and then run the thermal flashlight over the surfaces. The LED on the thermal flashlight changes color according to the temperature so when you check out the photo you’ll see exactly where the hot and cold spots in the room are.
