Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation emitted by a heated surface. They are used in a variety of applications where direct temperature measurement is not ...
Color sensing (as well as detecting empty spaces) settled on IR-based sensors commonly used in line-following robots. You can watch the clock in action in the video embedded below just under the ...
affordable and accurate handheld infrared thermometers became available and used in a wide variety of applications. Infrared thermometers have a lens that focuses infrared light from an object onto a ...
it detects a rapid change of infrared energy and sends a signal. PIR sensors are used for applications such as automatically turning on lights when someone enters a room or causing a video camera ...
