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) ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

Since v0.8.2, infrared control from various IT remotes is supported for ESP8266 and since v0.9.0 for ESP32, too. A dedicated infrared receiver module is required. (KY-022 or TSOP38238 are confirmed to ...

(InfraRed remote control) A handheld, wireless device used to operate audio, video and other electronic equipment within a room using light signals in the infrared (IR) range. Infrared light requires ...
