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 ...

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 ...

This pair of musical keyboard hacks both use light to detect inputs. The pair of tips came in on the same day, which sparks talk of consipiracy theory here at Hackaday. Something in the weather must ...

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 ...

Take a Si1120 Ir-LED sensor and seven infrared LEDs. Add in one ultra-low power C8051F930 MCU. Mix thouroughly. The result is Silicon Labs' $199 Si1120 Evaluation Kit. It could also be your next 3D ...

Vishay’s VCNL4100 is an IR proximity sensor that works up to 1m, and includes an ambient light sensor. Inside, it combines an infra-red (940nm) emitter, photo detectors for proximity and ambient light ...

Proximity sensors have been around on our phones for quite a while and apart from detecting the presence of a human ear, it also locks the screen when the phone’s in the pocket and enables gesture ...
