20Pcs Geekcreit® IR Infrared Obstacle Avoidance Sensor Module For Smart Car Robot 3-wire Reflective Photoelectric

Description The sensor module adaptable to ambient light having a pair of infrared emitting and receiving tubes transmitting tubes emit infrared certain frequency when the direction of an obstacle is detected reflection surface the infrared reflected is received by the reception tube After a comparator circuit processing the green light is on but the signal output interface output digital signal a low level signal you can adjust the detection distance knob potentiometer the effective distance range of 2 30cm the working voltage of 3 3V 5V The detection range of the sensor can be obtained by adjusting potentiometer with little interference easy to assemble easy to use features can be widely used in robot obstacle avoidance avoidance car line count and black and white line tracking and many other occasions Parameters 1 When the module detects an obstacle in front of the signal the green indicator lights on the board level while the OUT port sustained low signal output the module detects the distance 2 30cm detection angle 35 the distance can detect potential is adjusted clockwise adjustment potentiometer detects the distance increases counterclockwise adjustment potentiometer reducing detection distance 2 The sensor active infrared reflection detection target reflectivity and therefore the shape is critical detection distance Where the minimum detection distance black white maximum small objects away from a small area a large area
