This Infrared transmitter can activate IR based switching circuits from a distance of 10 meters or more. It is a high power IR transmitter driving two IR LEDs through a Darlington transistor BD 139 to ...
Most of the IR remotes work reliably within a range of 5 metres. The circuit complexity increases if you design the IR transmitter for reliable operation over a longer range, say, 10 metres. To double ...
If you’re looking for “smart” home appliances, there’s no shortage of options on the market. Even relatively low-end gadgets are jumping on the Internet of Things bandwagon these days (for better or ...
Osram Opto Semiconductors was able to sink a surface-mountable infrared (IR) LED into a printed-circuit board, creating what it claims is the first the first flush-mountable version of its kind. The ...
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, ...
