Proximity Sensor

Object is sensed output 0, output 1 is not sensitive to the time, directly with 3V and 5V microcontroller IO port connected.
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 cm is measured against the white wall of) speed, suitable for smart car obstacle avoidance, black and white line tracking, anti-drop, product counters, cutting lines, liquid level detection.
