Waveshare Contact-Less Infrared Temperature Sensor

A contact thermometer needs to physically touch whatever it's measuring, which doesn't work for a moving part, a surface too hot to probe safely, or a target that simply can't be reached with a physical sensor. This infrared sensor reads temperature remotely instead, measuring the infrared radiation a surface emits and converting that into a temperature reading without any physical contact required. Useful for monitoring a spinning motor's bearing temperature, checking a hot surface safely, or any measurement scenario where touching the target isn't an option.
