Buongiorno a tutti;
Avrei bisogno di un aiuto, ho acquistato questo sensore per misurare la qualità dell’ aria.
Dato che nel progetto che sto facendo necessito di 2 sensori ho di conseguenza bisogno di cambiare L indirizzo di uno dei due; qualcuno sa dirmi se è possibile cambiarlo e come?
Grazie in anticipo
Goodmorning everyone; I need help, I purchased this sensor to measure air quality. Since in the project I'm doing I need 2 sensors, I therefore need to change the address of one of the two; can anyone tell me if it is possible to change it and how? Thanks in advance

Hi, @davideonesti
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

From what I can see it doesn't seem you can change the address.
However there are other ways of using two I2C devices with the same address together.

Here is a solution I found to work and the url for it is in the image.

sorry but I can't find the page and I should see the associated program

That link is over tow years old so mat have expired.

Try this link to another forum thread, I have even supplied a sample of my code?

This is the link cited in the circuit.

can I read the values ​​of the 2 sensors at the same time in this way?Because my aim is to monitor two rooms and see both values ​​on the LCD display at the same time

Yes you can, you read them one after the other as if they had different addresses.

It just there is a couple of more lines of code involved but that won't change the appearance of simultaneous readings.
