Sensirion Sfm4100 και arduino uno

[kostasmantzios]

Λοιπον συνδεσα στο α4 και α5 και μου δουλευει και με τα δυο που μου στειλατε και 0χ81 και 0χ01

Μονο που δεν μου δειχνει σταθερες τιμες ηρεμιας. Κυμαίνονται απο -16 εως 20 ενω όταν φυσαω μεσα δειχνει πχ. 2459 η 1689

βρηκα και αυτον τον κωδικα φαινεται καλυτερος? μου δίνει τα ίδια.
