Cytron Technical Forum

Hello Mr/Mrs, I am Fairuz. I already bought an IR Sensor Click from cytron. I am having problem test the sensor connect to the arduino. I dunno either my connection between the sensor and arduino is not working or the coding is not working. Can you help me to overcome this problem by provide a tutorial using IR Distance Click with Arduino CT CYTRON UNO ? Thanks.

Hi mdFairuz4,

Could you share a few clear photos of your hardware setup? And your coding as well.

Thanks.

Hello, Mr. Idris, First thing first, thank you for willing to reply my request. Okay, here the picture i attached together. And the coding is provided as follow :

CODE: SELECT_ALL_CODE

/*=========================================================
Infra-Red distance measures: Send distance value in centimeters to serial
Connection the sensor to the Arduino:
  sensor - arduino
     VCC - 5V
     Gnd - GND
     OUT - A0

Briefing: 
This program has the sole purpose of measuring distances with the Infra-Red sensor.
It uses a previous calculated regression to convert analogRead values into distance values.
*/

const int irsensorpin = A0;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
}

void loop(){

 
  // Reads the InfraRed sensor analog values and convert into distance.
  int sensorValue = analogRead(irsensorpin);
  double IRdistance = 187754 * pow(sensorValue, -1.51);
 
  Serial.println(IRdistance);
 
  // A delay is added for a stable and precise input
  delay(100);
}

I connect the sensor to arduino by OUT to A0,
5V to 5V,
3.3V to 3.3V,
GND to GND,

I tried with this coding the serial monitor does not give any number. Looking forward for the reply. Thank Sir

Sorry for the messy table in the picture.

Hi, I just update the Getting Started with IR Distance click on Cytron Tutorial page. Please refer to this link: http://tutorial.cytron.com.my/2017/07/25/getting-started-ir-distance-click/

Thanks.

Very good tutorial. Thanks for the information ! Really appreciate it.


Thanks Mr Idris

By the way Mr Idris, I used the previous coding that I post earlier, However the distance(output) did not give a good reading. Can i know how to create the formula based on ADC & Voltage reading ?


I need accurate & precise reading in my project. Really appreciate if i know how to create own formula..
Thank you
