I2C With SENSEVAL-SCB4XV1 and Arduino UNO

Hello,

Please bear with me as I'm very new to I2C.

I have a SENSEVAL-SCB4XV1 board that is composed of 3 sensors. I'm only interested in the SHT40-AD1B and SGP40-D-R4 sensors. The board's Vdd is 1.7V—3.6V and from the specs sheet for the sensors, the SDA and SCL are 3.3V more or less. What I'm uncertain about is the SDA and SCL for the Uno since the pins usually output 5V. Can I add pull-up resistors between Vdd and the sensors' I2C lines and connect the Arduino's I2C pins directly to the sensors?

Thanks in advance!

If your sensors are not 5V tolerant, you need level shifters to translate between the Uno's 5V signal levels and the sensors 3.3V signal levels.
