I have to connect 3 i2c pressure sensors to my Cerb40.Two sensors are operating at 3.3v and the third one is operating at 5v.
The 2 two 3.3 sensors are MS5611 barometric pressure sensors and they are already operational:
I have to add this HCLA differential pressure sensor:
The HCLA sensors are also available with 3.3v interface. Unfortunately, I have to experiment now with the 5v sample that I have.
The idea is to power the HCLA sensor at 5v while the others are powered at 3.3v. And then to share the ground and the i2c lines.
My question is:
Is this wise? Is it possible to mix 3.3 and 5v devices through one 12c interface?
