Hi Jenna, 

I have a last question.

what will give more the data via the filter with the command data = lwlp.getfilterData();?

Where may I find the answer?

Thank you again for your support. 

Hello Jenna , following your question I checked the I2C scanner:

#include <Wire.h>

void setup()

{

Wire.begin();

Serial.begin(115200);

while (!Serial); // Leonardo: wait for serial monitor

Serial.println("\nI2C Scanner");

}

void loop()

{

byte error, address;

int nDevices;

Serial.println("Scanning...");

nDevices = 0;

for(address = 1; address < 127; address++ ).  

{

Wire.beginTransmission(address);

error = Wire.endTransmission();

if (error == 0)

{

Serial.print("I2C device found at address 0x");

if (address<16)

Serial.print("0");

Serial.print(address,HEX);

Serial.println(" !");

nDevices++;

}

else if (error==4)

{

Serial.print("Unknown error at address 0x");

if (address<16)

Serial.print("0");

Serial.println(address,HEX);

}

}

if (nDevices == 0)

Serial.println("No I2C devices found\n");

else

Serial.println("done\n");

delay(5000); // wait 5 seconds for next scan

} 

I changed “1 ” for “0” right now and you were right. Now the scanner see the device :)

Hello Sir

Thank you for your repply.

In fact,when i am using an I2C scanner, i dont see it at all.

I can see my other I2C sensor but not this one.

I tried with different  wires and it doesn't change anything.

In fact i have 2 sen0343 sensor and no one is working. Same issue for both
