The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide.

This represents a significant step forward in astronomical infrared technology because it is the first time a sensor with anywhere near this many infrared pixels has been trained on the sky.

Dogs have a type of infrared sensor in the tip of their nose which enables them to detect minute changes in temperature such as when other animals are nearby, according to new research.

One could argue that it would have been easier to connect a temperature sensor to the ATtiny85, but by synchronizing the case fan to the computer-controlled GPU fan, [Randy] is able to manually ...

An IR sensor is cheap, though, and they are already frequently integrated into a smartphone for face unlock and camera effects, so Huawei was able to quickly react to the pandemic.
