Hello,
I want to use two SFM300 Flowmeters with my Arduino.
The default i2c address of this sensor is 0x40 as defined in the datasheet.
How can I change the address of one sensor so I can use both? Or can I even change it? I've read that for some sensors it is not possible to change the i2c address at all. I could not find anything in the datasheets provided by Sensirion.
I attached them here also.
If I cannot change the address what can I do instead? I found out I can use an I2C multiplexer board. Are there any other solutions or is this the best one?
Thank you in advance
Yahuu
