PAJ7620u2 issues on UNO

Using Arduino Sensors
1

Hi guys

I have taken the 9 gesture sample & modified/trimmed it to the following. The eventual goal is to drive a servo.

The sensor is connected to UNO's 3.3v supply.

The code works for the first minute ot 2 & then stops working.

Not sure what i am doing wrong.

#include <Wire.h>
#include "paj7620.h"

/* 
Notice: When you want to recognize the Forward/Backward gestures, your gestures' reaction time must less than GES_ENTRY_TIME(0.8s). 
        You also can adjust the reaction time according to the actual circumstance.
*/
#define GES_REACTION_TIME		600				// You can adjust the reaction time according to the actual circumstance.
#define GES_ENTRY_TIME			1000				// When you want to recognize the Forward/Backward gestures, your gestures' reaction time must less than GES_ENTRY_TIME(0.8s). 
#define GES_QUIT_TIME			1200

int posServo = 90;
void setup()
{
	uint8_t error = 0;

	Serial.begin(9600);
	Serial.println("\nPAJ7620U2 TEST DEMO: Recognize 9 gestures.");

	error = paj7620Init();			// initialize Paj7620 registers
	if (error) 
	{
		Serial.print("INIT ERROR,CODE:");
		Serial.println(error);
	}
	else
	{
		Serial.println("INIT OK");
	}
  Serial.print("servo int at: ");
  Serial.println(posServo);
	Serial.println("Please input your gestures:\n");
  posServo = 90;
}

void loop()
{
	uint8_t data = 0, data1 = 0, error;
	
	error = paj7620ReadReg(0x43, 1, &data);				// Read Bank_0_Reg_0x43/0x44 for gesture result.
	if (!error) 
	{
    //Serial.println (data);
		switch (data) 									// When different gestures be detected, the variable 'data' will be set to different values by paj7620ReadReg(0x43, 1, &data).
		{
			case GES_RIGHT_FLAG:
				delay(GES_ENTRY_TIME);
					Serial.println("Right"); 
         if(posServo <= 180)
         {
          posServo += 90;
          Serial.print ("  Servo: ");
          Serial.println(posServo);         
         }
				break;
			case GES_LEFT_FLAG: 
				delay(GES_ENTRY_TIME);
					Serial.println("Left");
         if (posServo > 0)
         {
          posServo -= 90;
          Serial.print ("  Servo: ");
          Serial.println(posServo);
         }
				break;  
		}
	} else {
    Serial.println (">>Error!");
	}
	delay(100);
}

Would appreciate some guidance.

Thanks, Puneet

I get the same with the sample sketch. Stops working after about a min.

Switched boards this morning and still the same.

Could it be a faulty sensor?

Also I have left the interrupt pin disconnected...believe it needs to be low.
