Obstacle Avoidance Sensor Module:

• Robots frequently use these sensors to avoid obstacles.
• It detects obstructions using infrared.
• This Infrared Obstacle Avoidance Sensors Module has a builtin IR transmitter and IR receiver that sends out IR waves and then looks for the reflected IR waves to detect the presence of any objects in front of the sensor module.
• The module has an on board potentiometer that let users adjust the detection range.
• This sensor  can be used in light and complete darkness.
