Measuring range: Adjustable range from 1mm to 60cm, the closer the distance, the more stable performance, and white reflection farthest
Detection distance can be adjusted with potentiometer, clockwise to increase and counterclockwise to reduce
Output: TTL 0/1, when the sensor received the reflected infrared, the indicate LED light and output TTL 0, otherwise output the TT L 1, and the LED off.
Output port can be directly connected to the SCM IO port, also can drive a 5V relay module or buzzer module directly
Widely used in robot obstacle avoidance, car obstacle avoidance, assembly line counting and black white line tracking
