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 ...

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 ...

STMicroelectronics is launching a human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The ...

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 ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...
