Arduino KY-032 Obstacle avoidance sensor modules Infrared Obstacle Avoidance Sensor returns a signal when it detects an object in range. The range of the sensor is around 2-40 cm distance. It operates at 3.5 to 5 volts at around 20 milliamps. The Obstacle Avoidance Sensors usually come in two types – with 3 and 4 pins. This is the 4 pin version Sensor Module and has an optional Enable pin. An infrared obstacle avoidance sensor is designed to detect obstacles or the difference in reflective services. This sensor is made with black and white lines tracing the car ran without a black line on white paper, available in concrete The yellow complex environment such as the black line patrol track. As long as the black line around the slightly lighter color than black can, eliminating the traditional moves so that environmental layout easier.
