Sen 0390

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
Zaki Naufal.Maulana 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.
Yeez_B Im using pin 13 for enable, vcc to vin, gnd to gnd, sda to pin 21, and scl to pin 22

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.

Yeez_B I use esp32, its same things or not? For code i use some example from library
Hi！
pls try this code.
