Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

This project involves creating a simple pyrometer (infrared thermometer) using an Arduino IDE. The device measures the temperature of objects without contact using an infrared sensor (e.g., MLX90614) ...

If you’ve ever needed a short-range remote control for a project, [firestorm] is here to help you out. He put up a great tutorial on using an IR remote to do just about anything with everyone’s ...
