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 ...

An IR sensor is located near the TV and wired to the receiver, which can be many feet away in the equipment rack. The receiver has an amplifier and an "IR blaster" that showers IR signals to all ...

For the last eight years, a team of researchers at Aalto University in Finland has been working to improve the efficiency of photodiodes, a type of infrared sensor that converts light into ...

Despite these breakthroughs and a surge in demand for more sophisticated infrared sensor systems, performance improvements have slowed in recent years. This is largely due to the limitations of ...
