This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to ...

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 ...

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.

Passive infrared (PIR) sensors detect infrared energy radiating from objects within their field of vision.

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.

The US is anticipated to become a key infrared gas sensor industry market. These characteristics allow for the integration of infrared gas sensors into a variety of machinery and apparatus.

Specifically, it’s inside the new Changhong H2. The sensor works by bouncing infrared off an object and registering the unique molecular fingerprint that bounces back.
