Product description: Refletive IR - infrared receiver with LM393 comparator - Unit expansion module - M5Stack U175
Reflective IR Unit is an infrared sensor module that, thanks to IR technology, can accurately detect reflected light from various objects. The module generates the appropriate voltage value based on the intensity of infrared signals reflected from obstacles. The integrated LM393 comparator circuit converts analog signals into reliable digital signals that can be easily processed. One of the key elements of Reflective IR is a digitally controlled LED indicator that enables quick and intuitive monitoring of the sensor's operating status, which is particularly useful in both laboratory and engineering projects. The module is also equipped with an adjustable 10k potentiometer that allows you to adjust the sensitivity and detection threshold, allowing you to optimize the operation of the receiver in various conditions and applications. This flexibility makes the Reflective IR Unit a versatile solution for applications requiring object detection, motion tracking, distance measurement and automation.
