An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

Schematic of IR Beam Breaker Circuit TSOP1738 IR sensor module responds to only 38 kHz pulsed infrared rays. It will not sense continuous IR ray from the IR LED. So a transmitter circuit (as one in TV ...

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.

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.

Imec has developed a prototype high-resolution short-wave-infrared (SWIR) image sensor with a record small pixel pitch of 1.82 µm. The sensor is based on a thin-film photodetector that is ...

Israeli startup Adasky, which seeks to mass-produce a far-infrared sensor for driverless cars, has raised $20 million as part of a larger round.

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.
