Product Overview
The IR infrared obstacle avoidance sensor module is designed to detect objects using infrared transmission and reflection technology. It consists of an IR transmitter and IR receiver. When an object comes in front of the sensor, the emitted infrared light is reflected back to the receiver, thereby triggering the output signal. The module includes an adjustable potentiometer to set detection sensitivity and distance. It is suitable for robotics projects automation systems and training panels.
