Is that tasty baked snack still too hot to eat? Omron's D6T contactless infrared thermal sensor should take the guesswork out of it and help to avoid future cases of burny-mouth. Hook it up to a phone, point it at food or drink, and it'll display heat levels on-screen. Aside from snack safety, the device is also intended as a general presence sensor. The thermal detection negates the need for motion tracking and allows for additional features, such as power saving (switching off lights etc.) when people aren't around. Want to see it in action? There's a video generating heat right after the break.
