NTE30116 Tinted Blue 5mm Infrared LED Emitter (940nm) SM0038 Photo Module for PCM Remote Control System (38kHz) The principle of this setup is somewhat simple and self-explanatory. In this circuit, ...

Krejci’s design, while affordable, offers an 8×8 resolution, which is the maximum output of the AMG8833 infrared sensor array. DIY Arduino thermal camera Watch this video on YouTube.

While thermal imaging cameras – even inexpensive homebrew ones – have an infrared sensor that works a lot like a camera CCD, there is a cheaper alternative.

Some Python code takes care of converting it into an image. Perhaps you don’t need a camera, but having a way to communicate with an $11 IR temperature sensor might come in handy someday.

Circuit Diagram Here you can find the circuit diagram for the Bidirectional Counter using Arduino. The circuit diagram below represents how an Arduino, a pair of IR sensors, and the LCD display are ...
