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. Specification     Operating Voltage: 3.3-5V Interface: I2C interface x1 Interrupt pin x1 Detecting range: 100mm Module size: 18.3x16.4mm Layout RGB and Gesture Sensor OPSITIVE 名称 RGB and Gesture Sensor REVERSE 功能描述 SDA I2C DATA PORT SCL I2C CLOCK PORT GND GND VCC VCC INT Interrupt Output Tutorial We will use a simple example to teach you how to use the gesture Sensor. Our goal is to make the sensor to detect gestures up and down around the waving.

Our goal is to get the sensor detect the gesture UP, DOWN, left and right. Here we begin. Codes download  Download and install the RGB and Gesture Sensor Library: Click to download library files https://github.com/Arduinolibrary/DFRobot_RGB_and_gesture_sensor/raw/master/SparkFun_APDS 9960.zip Arduino Library Installation Tutorial https://www.arduino.cc/en/Guide/Libraries#.UxU8mdzF9H0 Next, we need to open the ARDUINO IDE, and copy the following simple code to the IDE window. Then select the right serial port and board (Arduino UNO). Wave your hand in front of the sensor, see what happen on the serial port. Sample Code 1 #include 2 #include 3 4 // Pins 5 #define APDS9960_INT 2 // Needs to be an interrupt pin 6 7 APDS9960 apds = APDS9960(); 8 int isr_flag = 0; 9 10 void setup() { 11 12 // Initialize Serial port 13 Serial.begin(9600); 14 Serial.println(); 15 Serial.println(F("--------------------------------")); 16 Serial.println(F("APDS-9960 - GestureTest")); 17 Serial.println(F("--------------------------------")); 18 19 // Initialize interrupt service routine 20 attachInterrupt(0, interruptRoutine, FALLING); 21 22 // Initialize APDS-9960 (configure I2C and initial values) 23 if ( apds.init() ) { 24 25 Serial.println(F("APDS-9960 initialization complete")); } else { 26 27 Serial.println(F("Something went wrong during APDS-9960 init!")); } 28 29 // Start running the APDS-9960 gesture sensor engine 30 if ( apds.enableGestureSensor(true) ) { 31 32 Serial.println(F("Gesture sensor is now running")); } else { 33 34 Serial.println(F("Something went wrong during gesture sensor init!")); } 35 } 36 37 void loop() { 38 if( isr_flag == 1 ) { 39 handleGesture(); 40 if(digitalRead(APDS9960_INT) == 0){ 41 apds.init(); 42 apds.enableGestureSensor(true); 43 44 } 45 46 isr_flag = 0; } 47 } 48 49 void interruptRoutine() { 50 isr_flag = 1; 51 } 52 53 void handleGesture() { 54 if ( apds.isGestureAvailable() ) { 55 switch ( apds.readGesture() ) { 56 case DIR_UP: 57 Serial.println("UP"); 58 break; 59 case DIR_DOWN: 60 Serial.println("DOWN"); 61 break; 62 case DIR_LEFT: 63 Serial.println("LEFT"); 64 break; 65 case DIR_RIGHT: 66 Serial.println("RIGHT"); 67 break; 68 case DIR_NEAR: 69 Serial.println("NEAR"); 70 break; 71 case DIR_FAR: 72 Serial.println("FAR"); 73 break; 74 default: 75 Serial.println("NONE"); 76 77 } } 78 } 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.
