Why my Ambient Light Sensor SEN 0390, the ouput it just -1.00

2023-07-26 04:53:15

This is my variabel luxx for the lux meter, but still get -1.00

void luxx(){

  float l = myLux.lightStrengthLux();

  Serial.print("value: ");

  Serial.print(l);

  Serial.println(" (lux).");

  Blynk.virtualWrite(V1, l);

  delay(1000);

}

 

i already put the myLux in setup and the luxx in loop

According to the SEN0390 library, the code could work with the ESP32

You could use this I2C scanner to check if it's connect properly

 

And could you tell me your wire connection?

Like how you which PIN you connect the sensor to the ESP32.

Could you put your code, wire diagram here and tell us what kind of main baord you are using?

 

If you are using the Arduino, you could upload the I2C scanner to see if your SEN0390 is hooked up properly onto your main board.
