See a couple of random oscillograms below. Thus, the infrared emitter transmits bursts of 38kHz infrared signal modulated at 1kHz. The series resistor R1 sets the operating current (and hence the ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now ...

Over the years, you may have noticed a growing trend among homeowners implementing motion sensor lights for added security and convenience. These innovative lighting solutions not only illuminate your ...

Modern smartphones use proximity sensors for much more than just turning off screens during calls. These advanced sensors, powered by IR emitters and receivers, detect nearby objects like your hand or ...

Panasonic started the infrared array sensor business with its 8 x 8 thermopile array called Grid-EYE. Grid-EYE is a 64 pixel IR camera in an all-in-one compact SMD package. Based on Panasonic’s MEMS ...

If you’ve been watching Nintendo Switch 2 news like a hawk for the past few weeks, you may have spotted leaks about the new and improved Joy-Con controllers, and wondering just what an IR sensor is.
