Receiving infrared (IR) signals while conserving system power is difficult, and typically requires the inclusion of complex power-management routines in the firmware. You can avoid that problem by ...

This infrared repeater system is used to extend the range of an infrared transmitter used at an audio or video equipment at 10 m. The original signal is captured by the infrared receiver (figure 1), ...

Over on his YouTube channel [Electronic Wizard] has released a video that explains how infrared (IR) remote controllers work: IR Remote Controllers protocol: 101 to advanced. This video covers the NEC ...

Infra-red (IR) remotes are great, unless you’re in a hackerspace that’s full of crazy blinking lights and random IR emissions of all kinds. Then, they’re just unreliable. Some smart folks at Metalab ...

This project allows you to take the video recorder and satellite receiver remote controls upstairs, and operate the equipment from there. There is no additional cabling to install, the signal being ...

The new UB20M voltage detector IC in Fig. 1 enables zero-power sensing and listening. It allows circuit designers to eliminate standby power, to develop circuits that perform continuous monitoring ...
