Description
The LM393 IR Reflective Sensor with Comparator is a module used to detect obstacles using infrared. It uses the reflection of the IR beam to precisely respond to the presence of objects in range. When an obstacle is detected, a low state is generated at the output. The module is equipped with an LM393 comparator, which ensures stable operation even in interference conditions. The built-in potentiometer allows you to adjust the trigger threshold, which allows you to adapt the sensor to the ambient lighting. The mounting hole in the central part of the board makes it easy to install the device. The sensor is ideal for applications related to robotics and obstacle detection systems. Thanks to the digital output, it can be easily integrated with all development kits available on the market such as Arduino, Raspberry Pi, STM32, ESP32 and many others.
