The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

Infineon's RGB LED Lighting Shield is one two of Arduino-based evaluation boards created to showcase the capabilities of its ARM-based XMC1000 MCUs in lighting and motor control applications. Unlike ...

The sensor is intended as an alternative to pyroelectric sensors or PIR detectors in home automation, building automation, healthcare, security and industrial applications. Typically human presence ...

The sensor can provide 1080p (1920x1080) resolution at 60 frames per second (fps) or 720p (1280x720) at 90 fps, via a 2-lane MIPI serial output. The OH02A1S also integrates 2 kilobits of one-time ...
