The IR Obsctacle avoidance sensor is basically a sensor circuit.  It contain a transmitter circuit that sending infrared light and a receiver circuit that receiving infrared light. In order for the receiver to receive infrared light, the IR light must return by hitting an obstacle.

How to work The IR Obsctacle avoidance sensor

When the 5V operating voltage is applied to VCC and GND pins, the transmitter emits IR light. If the IR light that hits an obstacle returns to the receiver, the IR obstacle avoidance sensor gives HIGH signal from the S pin. If there is no obstacle and therefore the light does not return to the receiver, the LOW signal is received from S pin.

If you want, you can change the distance detection sensitivity with the help of the potentiometer on this sensor circuit. The effective detection distance of the IR obstacle avoidance sensor is between 2cm and 40 cm.
