The IR sensor array, ... Color sensing (as well as detecting empty spaces) settled on IR-based sensors commonly used in line-following robots.

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. Potentiometer tuning was a fiddly affair, but ...

Delivering thermal sensing solutions using IR array sensors is started. Since it enables high-precision and contactless thermal sensing they can be us. ... This solution has the following features: ...
