Description:_x000D_ This module provides a versatile infrared detection system solutions for automation machinery devices such as smart cars, robots. The sensor module is adaptable to ambient light. It has a pair of infrared transmitting and receiving tube. Transmitting tube sends out a certain frequency IR which will be reflected when detecting obstacles (reflecting surface) and received by receiving tube. After processing with comparator circuit, signal output interface outputs digital signal (a low voltage level signal). _x000D_ _x000D_ _x000D_ Features: _x000D_ When the module detects obstacles signal, red indicator lights on and OUT port continuous outputs low voltage level signals at the same time. _x000D_ Detection distance can be adjusted with potentiometer, clockwise to increase and counterclockwise to reduce. _x000D_ 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. _x000D_ Output port can be directly connected to the SCM IO port, also can drive a 5V relay module or buzzer module directly. _x000D_ Widely used in robot obstacle avoidance, car obstacle avoidance, assembly line counting and black white line tracking. _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Working Voltage: 3.3V-5V DC _x000D_ Working Current: >1A _x000D_ Detection Distance: 2~60cm _x000D_ Detection Angle: 35_x000D_ Size:_x000D_ Big Board: 42*38*12mm_x000D_ Small Board: 25*12*12mm _x000D_ Mounting Hole Diameter: 3mm _x000D_ _x000D_ _x000D_ Note:_x000D_ 1, Do not put probe toward sunlight. Sunlight will cause interference to module._x000D_ 2, Sensitivity should not be regulated excessively high because high sensitivity can easily lead to false trigger. _x000D_ _x000D_ _x000D_ Package Includes: _x000D_ 1 x Infrared Tracking Module Set
