SEN-14786.
I can not find out how to change an I2C address of this sensor in case if I want to connect more then one sensor on the same I2C bus with Arduino. I did an address scan and see that all of the sensors initially have same address 0x10. In their manual it is written that address is “configurable” between 0x10 and 0x78. But no words about how to do that change. If anybody can help, I will really appreciate that. Thank You!
Hi andrii,
This is not something we have tested yet and do not have specific instructions for, but it looks like page 16 of the [Product Manual has the most information regarding it. It has the register address and the values you can enter for it listed there. You will need to cycle power after adjusting that register for it to save the changes.
I hope this helps!](https://cdn.sparkfun.com/assets/d/9/e/c/d/TFmini-I__C-Product_Manual_V1.1_EN.pdf)
Could you please explain it a little deeper?
I have read that but don’t understand that.
Where abd how should I enter new register or address?
Hi again andrii,
Unfortunately, we do not have more information readily available covering how you would specifically go about doing that outside of what is listed in the Product Manual. You need to specifically call the I2C Slave Address register to change it. If you are not familiar with calling and controlling specific registers with I2C devices, our [I2C Tutorial would be a good place to start.
Arduino’s [reference page for the Wire Library will also have some good information on how you can read/write I2C registers using an Arduino.](Wire - Arduino Reference)](https://learn.sparkfun.com/tutorials/i2c)
