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 ...

Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, ...

Whether you're a student, hobbyist, or robotics enthusiast, this maze-solving robot project will help you understand the ...

From your smartphone’s face recognition feature to fancy fitness trackers and advanced night vision cameras, many sensors we use daily rely on infrared light detection. For the last eight years ...

IR receivers are commonly used to control components in a cabinet with closed doors that obstruct the line of sight required by infrared. An IR sensor is located near the TV and wired to the ...

We've gathered all there is to know about the brand-new Joy-Con IR sensors, from how they might be used to exactly what they are and where you'll find them on your new device. Keep in mind that ...

Get yourself some passive infrared sensors (PIRs) and maybe a smart camera just to be sure. But sometimes you can be sneaky instead, saving the cost of a sensor by using alternative techniques.
