IR Obstacle Avoidance Sensor Line Tracking Module for Arduino - Blue
Decription: - Detection distance can be adjusted by potentiometer; - Effective detection distance: 2~80cm - Detection angle: 35’ - Working voltage: 3.3~5V - Widely used in robot obstacle avoidance£¬ smart car£¬ infrared coconut for assembly line£¬ black and white line tracking£¬ etc - Automatically transmits infrared ray and detects reflection£¬ therefore the reflectivity and shape of the target is the key of detection distance; The detection distance of black is minimum£¬ white is maximum; And the object with small area has short detection distance£¬ large area has long detection distance; - LED: Power on: red light LED on; Green light on when obstacle is detected; - Clockwise adjust the potentiometer to increase the detection distance£¬ anticlockwise adjust to decrease; Note: The comparison voltage of threshold has been adjusted through potentiometer before delivery£¬ so do not arbitrarily adjust the potentiometer if there is no any special circumstances; - Usage: Connect VCC to power supply£¬ GND to ground£¬ OUT to controller I/O port or external interruption port - PCB double-layer plates processing£¬ fine workmanship£¬ reasonable layout£¬ good quality and 100% tested before delivery - Designed with one M3 screw mounting hole£¬ easy to install
