MH Z14 در مقابل MH Z19

Frank'n'Sense | Hackaday.io

07-07-2015 · Searching for NDIR sensors, I found the MH-Z14 from Winsen Sensor. It operates from 5V, has PWM and Analog outputs, as well as a serial UART interface. 5V isn't suitable for the ESP8266 UART but level shifters could be used. However, looking at the Winsen website, I also found the MH-Z19.

15-11-2020 · Ausgelesen wir der MH-Z19 per seriellem UART-Interface mit 9600 Baud, kann also ganz einfach angebunden werden. Wichtig ist, dass er mit 5 Volt versorgt wird. Er funktioniert zwar grundsätzlich auch mit 3,3 Volt, allerdings weichen die gemessenen Werte dann stark ab. Das Datenblatt nennt einen Spannungsbereich von 3,6 bis 5,2 Volt.
