Bar30 Pressure Sensor Arduino 3.3V?


(Angus Clark) #1

Is it possible to run the Bar30 sensor off the 3.3V on an Arduino Mega?


(Jacob) #2

Yes, you can do this. You need to use a logic level converter on the SDA and SCL lines to prevent damage to the Bar30.

Would this do the job? I’m in the UK and need it fast (Project deadline approaching!)

@TheAngusBurger - That level converter should work great!
