I2C addresses on humidity sensor HTU21D

Post by antonkuzubov »

We need to have 2 humidity sensors on our project. Can I change the address on one of them so it's not the same with another one, so I can get readings from both at the same time? How do I do that?

From product guide:
The HTU21D-F has a default I2C address of 0x40 and cannot be changed!
So, would need to use an I2C multiplexer:
