IR Infrared obstacle avoidance module

Description:

The sensor module light is adaptable to the environmentit has a pair of infrared transmitting and receiving tubetube infrared emit a certain frequencywhen detecting direction meet with obstacles (reflecting surface)reflected infrared receiving tubeafter the comparator circuit processinggreen indicator will light upat the same time signal output interface to output digital signal (a low level signal)can be through the potentiometer knob adjust the detection distanceeffective distance range 2 ~ 30cmworking voltage is 3.3V to 5V. The sensor detection range can be through the potentiometer to adjust and have small interferenceeasy to assembleeasy to useetccan be widely used in robot obstacle avoidanceobstacle avoidance carline countand black and white line tracking and so on many occasions.

 

Module parameters that

  • when the module detects obstacles in front of the signalthe green indicator on the circuit board light level and at the same time the OUT port output low level signalthe detection module from 2 ~ 30cm35°detection Angletest distance can be adjusted through the potentiometeradjustable potentiometer clockwisethe detection distance increases; Counter-clockwise tuning potentiometerdetection distance is reduced.
  • sensorsactive infrared reflection detectiontherefore the reflectivity and shape of the target is the key of the detection range. White one black detection rangeminimum maximum; Small area of the object distancelarge distance.
  • the sensor module output port OUT can be directly connected to the microcontroller IO port canalso can drive a 5v relay directly; Connection mode: the VCC - VCC; GND - GND; The OUT - the IO the comparator USES the LM393working stability;
  • can be used for 3 to 5v dc power to power supply module. When power onthe red power indicator light lit;
  • 3 mm screw holeseasy fixedinstallation;
  • circuit board size: 3.2CM*1.4CM
  • each module is shipped already compare threshold voltage through the potentiometer to adjust goodnot special circumstancesplease do not arbitrarily adjust the potentiometer.

 

Module interface specification

  • VCC voltage is 3.3V to 5V converter (which can be directly connected to 5V single-chip microcontroller and 3.3V)
  • GND external GND
  • OUT of small plate digital output interface (0 and 1)

Kit include:

  • 1 x Obstacle Avoidance Sensor Module Infrared Module Reflection Photoelectric Sensor
