Infrared Obstacle Sensor Module Frequency & Distance Adjustment
The object is detected on output 0, output 1 not sensitive to time, directly with the IO port of the 3V and 5V microcontroller connected.
Detection distance 2-40cm, distance, good anti-jam. (Note: the infrared sensor can not detect all objects get the same distance, objects of different light reflectance colors of different objects near detected dark black short, 2-40cm sensor is measured against the white wall of)
This sensor made with black and white lines tracing the car without a black line on white paper, available in concrete The complex yellow environment like the black line patrol track. the black line around the slightly lighter color of the black can, eliminating the traditional moves, making the ambient arrangement simple.
The 3 to 6V sensor provides a wide range, suitable for 3V and 5V MCU systems.
With Enable, the EN terminal equals “1” when the sensor fails, equals “0” when it works. Skip the end cap of the sensor after the EN grounding plug (EN up to “0”). To use the EN pin when the jumper cap is removed.
The frequency adjustment potentiometer is used to adjust the carrier frequency of the infrared emission tube, the integration receiver 38KHZ, especially when the carrier frequency is sensitive. Resistor 502 transferred clockwise (that is, the launch tube at maximum and therefore with a resistance of the white wall tone 103, was transferred to the sensing distance the far so that the sensor in the best state

Here we use the obstacle avoidance module and 13 digital interface with LED to build a simple circuit, making the obstacle avoidance light, access the avoidance sensor to digital interface 3,
