Flir One - Click to see the full review

The Flir One is a clever little gadget that turns your Android or IOS device into a thermal infrared camera. The Flir One actually uses two cameras to capture two images before the MSX Technology merges them together to create one detailed image with thermal information, the Lepton™ camera, the most compact long-wave infrared sensor available, takes a thermal reading and the standard camera provides the physical detail in the image.
