CO2-Sensor MH-Z19B - Unsinnsbasis

Der MH-Z19B braucht nämlich laut Datenblatt Volt Betriebsspannung. Das WROOM02_EV ist hier voll bestückt zu sehen, aber für diese Anwendung ist das völlig unnötig. Man muss nur das bestücken, was man wirklich braucht und kann zum Beispiel den Low-Power-Timer und alle daran angeschlossenen Schaltungsteile weglassen; auch die Sensoren usw. brauchen nicht bestückt zu …

mh-z19 · PyPI

· Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off(MH-Z19B) are implemented at version or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 gas, also MH-Z19B module. If you have these devices or apparatus and try to use …
