1 .Object is sensed output 0 , output 1 is not sensitive to the time , directly with 3V and 5V microcontroller IO port connected.
2 .Sensing distance 2-40 cm, Distance, good anti-jamming capability . ( Note: The infrared sensor can not detect all objects get the same distance , objects of different colors of light reflectance of different objects closer darker black shorter distance detected , the sensor 2-40 % per annum
M is measured against the white wall of )
3 .Speed,Suitable for smart car obstacle avoidance , black and white line tracking , anti-drop , product counters, cutting lines , liquid level detection.
4 .This sensor is made with black and white lines tracing the car ran without 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.
5 .The sensor3 to 6V Supply, Wide range , suitable for 3V and 5V MCU system .
6 .With Enable , EN terminal is equal to \” 1 \” when the sensor does not work, equal to \” 0\” when working . Jump on the sensor end cap long after the EN grounding plug (EN long as \”0\” ) . To use the EN pin when the jumper cap is removed.
7 .Frequency adjustment potentiometer is used to adjust the carrier frequency of the infrared emission tube , because the integration receiver 38KHZ in particular when the carrier frequency is the most sensitive .The 502 resistor clockwise transferred do ( that is, the launch tube at maximum brightness ) , and then at a white wall tone 103 resistance , has been transferred to the sensing distance is the farthest so far so that the sensor will work in the best state of the
