3D Gesture Sensor mini

Introduction

The so-called 3D means three-dimensional， three dimensionalities, three coordinates, that is, there is length, width and height, simply say is stereoscopic. The sensor can realize gesture recognition in three-dimensional space. It uses electric near field sensing technology and we can put the sensor into the plastic box to realize gesture recognition and distance induction.

Specification

Working voltage: 3.3 to 5 v
Interface type: IIC
Gesture induction: 5 cm
Distance induction: 10 cm
Size: 72x54

Sample Code

Click to download the librarysample and library。how to intall library？ Code function: to realize gesture recognition in the direction of the up and down or so and clockwise and counterclockwise circle with fingers.

#include <Gesture.h>
#include <Wire.h>

int testPin= 7;
unsigned char cmd;

Gesture myGesture;

void setup()
{
  Wire.begin();        // join i2c bus (address optional for master)
  Serial.begin(9600);  // start serial for output
 pinMode(testPin, INPUT);
 Serial.write("3D Gesture sensor is now running....\r\n");
}

void loop()
{
  if(digitalRead(testPin)==0)
  {
   myGesture.I2C1_MasterRead(md.buf,26,0x42); //The address is:0x42
   cmd = myGesture.mgcProcMsg();     //process the message
          if(cmd != GI_NOGESTURE )
            {
                switch(cmd)
                {
                    case GI_FLICK_R:
                      Serial.println("RIGHT");
                        break;
                    case GI_FLICK_L:
                        Serial.println("LEFT");
                        break;
                    case GI_FLICK_D:
                     Serial.println("DOWN");
                        break;
                    case GI_FLICK_U:
                       Serial.println("UP");
                        break;
                    case GI_AIRWHEEL_CW://Clockwise in circles
                     Serial.println("CW");
                        break;
                    case GI_AIRWHEEL_CCW://Counterclockwise circles
                       Serial.println("CCW");
                        break;

                    default: break;
                }
            }
  }
 else  {};
}

Results

When using hand moving up and down or so and clockwise and counterclockwise circle, the serial port output the corresponding string.
