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
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.
arduino 2 i2c devices with same address
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.
