A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands ... I quickly rigged up a crude one-channel touch-free toggle switch using an Arduino Uno.

Infrared line tracker modules hardly need an in-depth explanation ... This is the crude Arduino Sketch. This code lets Arduino acquire signals rendered by the sensor module via digital pin 12 (D12) so ...

To replicate Krejci’s design, you need an Arduino UNO Rev3 board, an AMG8833 infrared sensor module, and an 8×8 RGB LED matrix. The device collects 64 values from the infrared sensor and uses ...

today introduced two new fixed-gain infrared (IR) sensor modules designed to lower costs and increase stability for outdoor sensor applications. Offering typical irradiance of 1.3 mW/m² in ...
