HALJIA 4-Channel Infrared Tracking Obstacle Avoidance Sensor Module 4CH IR Line Track Follower Sensor PCB Board Compatible with Smart Car/Arduino

• When the module detects obstacles signal, red indicator lights on and OUT port continuous outputs low voltage level signals at the same time
• Effective detect range of 2 ~ 60cm, working voltage of 3.3V-5V. The detection range of sensor can be adjusted by a potentiometer,clockwise to increase and counterclockwise to reduce
• Target's 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
• 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
• Widely used for robot obstacle avoidance, car obstacle avoidance, assembly line counting and black white line tracking
