This is an IR beam breaking alarm ideal to use in entry or passages. It is based on the working of the popular IR sensor Module TSOP1738 which senses 38 kHz Infrared pulses from the IR LED of the ...

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 ...

Thanks to an IR proximity sensor, [romain] can interrupt the cycle and get the date, time, temperature, or even a smiley animation depending on the number of hand passes over the sensor.

3. IR LED driving circuit. Based on experience, the TIP121 Darlington transistor is a good option for this application. This device will allow us to drive a high current load with a low base current.

Some smart folks at Metalab in Vienna, Austria cut out the IR middle-man with a couple transistors and some audio software. They call the project HDMI Whisperer, and it’s a cute hack.

OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, today announced the OH02A1S—the world’s first RGB-IR medical image ...
