I2C bus switch PCA9545 with arduino and thermal sensor

Projects Programming

Hi everyone, I am doing a project of connecting two thermal sensor omron d6t that have the fixed address to the arduino uno. Because the sensor address is fixed, I use the PCA9545 I2C-bus switch to connect the SDL and SCL pins of sensors to arduino.

The problem I face now is I do not know how to program the PCA9545 with arduino, can anybody help me :frowning: please.

Wouldn't the information you need be in the PCA9545 data sheet?

What's wrong with the PCA9548A ?
Adafruit has a tutorial for it.
