IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

Meross has announced the launch of its new 3-in-1 smart sensor, the MS605. It uses triple detection technology, combining radar, infrared and light sensing, to reduce false alerts and deliver more ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

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 ...

From self-driving cars to facial recognition, infrared sensors are all around us and our novel semiconductor research is taking this technology to the next level. Phlux - a Sheffield spinout -has ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

Developed as an alternative to passive infrared (PIR) sensors, STMicroelectronics has launched its ultra-low-power STHS34PF80 IR sensor for human-presence and motion detection in alarm and security ...
