“The LM393 Photoelectric Sensor is an essential module for robotics and industrial automation. It uses a 5mm wide slot to house an infrared transmitter and receiver. When an object passes through the slot and breaks the light beam, the module output changes state. This makes it perfect for measuring motor speed (RPM) or counting objects on a conveyor belt.
