Vull obtenir valor de CO2 fent servir MHZ19. He provat aquest codi amb Arduino uno R3, però sempre obtinc aquest resultat (CRC 0/0). No entenia on està el problema. Vaig enllaçar A0 amb TX de sensor i A1 amb RX, vaig alimentar la targeta amb 3,3V / Vin per visualitzar el resultat a …
20210111· Chinese carbon dioxide sensor came to me without pin description. I had to sort it out by myself in order to connect to Arduino Uno.
However I found a reasonably priced sensor for free in the Winsen MHZ19 when I was scavenging an AC unit for parts. The MHZ14, MHZ16 and MHZ18 are also useable. But I understand the MHZ18 is quite expensive (92 euro''s at aliexpress). The MHZ16 and MHZ19 are both about 2530 euro. The MHZ19 has 3 ways of reading the CO2 concentration. It has a Tx/Rx UART, It has an analog output and it ...
