Hi, I’ve recently been trying to read from two Bar30 sensors using a Jetson NX, and I’m running into an I2C address conflict. Does anyone know if it’s possible to change the address on the Bar30

Hi @dada -

Welcome to the forums!!

It’s not possible to change the address, but you can use an I2C multiplexer to get readings from both. This user seems to [have gotten that working using a generic guide.](https://discuss.bluerobotics.com/t/multiple-celsius-fast-response-temperature-sensors-with-multiplexor/7092/8)
