Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet, ...

To guarantee measurements from infrared (IR) photonic sensors with certain accuracy, radiometric calibration (RC) is implemented to determine the radiometric responsivity of sensor and usually be ...

Researchers at Northeastern University have developed a next generation smart sensor for the Defense Advanced Research Projects Agency (DARPA) that is capable of identifying infrared (IR) wavelengths ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

We may receive a commission on purchases made from links. We've grown a little spoiled. At some point during the progression of televisions and media devices, remote controls went from infrared ...

Thermal infrared (IR) energy is emitted from all things that have a temperature greater than absolute zero. Human eyes, primarily sensitive to shorter wavelength visible light, are unable to detect or ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet, ...

A very interesting remote controlled alarm circuit using TSOP1736. Routing of an electric cable to attach a calling bell switch near the bed of an old age/patient is not a good idea. Here is an ultra ...
