AS7262 Visible spectral sensor but I just need the Red

Development Boards Arduino
1

I’m attempting to retrieve only the red wavelength data off of the AS7262 Visible spectral sensor but not having the greatest luck modifying the sample code. Sample code 1 gives you a list of different functions that can be implemented and one of those include “int getRed();” but I cant figure out how to implement this into the existing sample . Thank you for the help

This is a library written for the AS726X Spectral Sensor (Visible or IR) with I2C firmware

specially loaded. SparkFun sells these at its website: www.sparkfun.com

It looks like the printMeasurements function prints everything. Has that worked for you?

You can try something like Serial.println(sensor.getRed());

Hi,

The simplest way of doing is:

#include "AS726X.h"

AS726X sensor;

int redColor =0;

void setup() {
  sensor.begin();
}

void loop() {
redColor = getRed();
Serial.println(redColor);
  sensor.takeMeasurements();
  sensor.printMeasurements();
}
