Introduction

  • The sensor module to ambient light adaptation ability, which has a pair of infrared transmitting and receiving tubes, tube launched a certain frequency infrared. When detection direction meets the obstacle (reflector), infrared reflection back is received receiving tube, after the comparator circuit processing, green indicator light, also signal output interface to output digital signal (a low level signal), through the potentiometer knob adjusts the detection distance, a range of effective distance 2 ~ 30cm, the working voltage of 3.3v-5v. Detection range of the sensor can be through the potentiometer adjustment, with little interference, convenient assembly, easy to use, and can be widely applied to robot obstacle avoidance, obstacle avoidance of car, line count and black and white line tracking and so on numerous occasions.

Feature

  • When the signal is detected by the module, the green indicator light is on the circuit board, and the OUT port is continuously low level signal, the detection range is 2 ~ 30cm, the detection angle is 35 degrees, the detection distance can be adjusted by the potentiometer, the detection range is increased; the counter clockwise potentiometer, the detection range is reduced.

  • Sensor active infrared reflection detection, so the target's reflectivity and shape is the key to detect distance. Black detection distance is the smallest, white is the largest; small area of small objects, large distance.

  • Sensor module output port OUT can be directly connected with the microcontroller IO port can be directly driven by a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO

  • The comparator uses LM393, work stability;

  • Cpower is turned on;

  • With 3mm screw hole, easy to fix, install;

  • Circuit board size: 3.2CM*1.4CM

  • Each module in the delivery of the threshold has been compared to the voltage through the potentiometer adjustment, non special circumstances, do not arbitrarily adjust the potentiometer.

Module interface

  • VCC external 3.3V-5V voltage (can be directly connected with the 5V microcontroller and 3.3V microcontroller)

  • GND external GND

  • Small OUT digital output interface (0 and 1)

Shipping List
