1.When the module detects obstacles signal, red indicator lights on and OUT port continuous outputs
low voltage level signals at the same time
2.Effective detect range of 2 ~ 60cm, working voltage of 3.3V-5V. The sensor's detection range
can be adjusted by a potentiometer,clockwise to increase and counterclockwise to reduce
3.Target reflectivity and shape is the key point of detection distance.
Small and black objects have minimum detection distance, while large and white ones have maximum distance
4.Output port can be directly connected to the SCM IO port, also can drive a 5V relay module or buzzer module directly,
Connection: VCC-VCC; GND-GND; OUT-IO
5.Widely used in robot obstacle avoidance, car obstacle avoidance, assembly line counting and black white line tracking
6.the comparator uses LM339,work stably;

Note:
1, Do not put probe toward sunlight. the probe will be interfered by Sunlight .
2, Sensitivity should not be regulated excessively high because high sensitivity can easily lead to false trigger.
