SEN0187 RGB Color and Gesture Sensor For Arduino

Introduction

The sensor module uses the APDS-9960 chip, this is a single 8 pin package digital RGB, ambient light, short and gesture sensor device. The device is compatible with I2C interface, with an interruput pin. And short-range and gestures are measured with infrared LED. RGB and environmental light perception measurement function could work under a variety of light conditions, such as covering by a variety of damping materials including a piece of dark glass. In addition, the integrated UV-IR shading filter can realize ambient light and color temperature detecting.

How to use

In this section, we will use a simple experiment to teach you how to use our gesture sensor. Our goal is to get the sensor detect the gesture UP, DOWN, left and right. Here we begin.

Sample Code

#include <Wire.h>
#include <SparkFun_APDS9960.h>

// Pins
#define APDS9960_INT    2 // Needs to be an interrupt pin

SparkFun_APDS9960 apds = SparkFun_APDS9960();
int isr_flag = 0;

void setup() {

  // Initialize Serial port
  Serial.begin(9600);
  Serial.println();
  Serial.println(F("--------------------------------"));
  Serial.println(F("APDS-9960 - GestureTest"));
  Serial.println(F("--------------------------------"));

  // Initialize interrupt service routine
  attachInterrupt(0, interruptRoutine, FALLING);

  // Initialize APDS-9960 (configure I2C and initial values)
  if ( apds.init() ) {
    Serial.println(F("APDS-9960 initialization complete"));
  } else {
    Serial.println(F("Something went wrong during APDS-9960 init!"));
  }

  // Start running the APDS-9960 gesture sensor engine
  if ( apds.enableGestureSensor(true) ) {
    Serial.println(F("Gesture sensor is now running"));
  } else {
    Serial.println(F("Something went wrong during gesture sensor init!"));
  }
}

void loop() {
  if( isr_flag == 1 ) {
    handleGesture();
      if(digitalRead(APDS9960_INT) == 0){
      apds.init();
      apds.enableGestureSensor(true);
    }

    isr_flag = 0;
  }
}

void interruptRoutine() {
  isr_flag = 1;
}

void handleGesture() {
    if ( apds.isGestureAvailable() ) {
    switch ( apds.readGesture() ) {
      case DIR_UP:
        Serial.println("UP");
        break;
      case DIR_DOWN:
        Serial.println("DOWN");
        break;
      case DIR_LEFT:
        Serial.println("LEFT");
        break;
      case DIR_RIGHT:
        Serial.println("RIGHT");
        break;
      case DIR_NEAR:
        Serial.println("NEAR");
        break;
      case DIR_FAR:
        Serial.println("FAR");
        break;
      default:
        Serial.println("NONE");
    }
  }
}

Other functions

This sensor not only support gesture recognition, but also the range, ambient light and RGB color detecting. The specific examples can be found in the library EXAMPLES folder. so you can also develop other application according to your requirement.
