After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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.

The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide. Potentiometer tuning was a fiddly affair, but ...

The sensor operates at 5V for Arduino and 3.3V for Raspberry Pi, ensuring seamless integration with these popular microcontroller and microcomputer platforms.

Arduino Based Wireless Intrusion Detection Using IR Sensor and GSM Intrusion Detection Systems (IDS) strive to catch computer system intrusion & utilize by any garnering and analyzing data.

STMicroelectronics has introduced a multi-spectral ambient light (plus UVA and near-IR) sensor, with flicker detection, in a package smaller than 1mm x 2mm. Applications are foreseen with phone ...
