CO2 Messung mit FPGA -

Jan 13, 2021· Interessant, dass der MH-Z19 die Auto-Kalibrierung nicht abschalten kann. Was in bestimmten Situationen (wie die Hühnerstall Anwendung) ein muss ist. Hab übers WE jetzt auch noch einiges Nachgelesen, und ja, bei der CO2 Messung steckt der Teufel im Detail und man muss sich schon etwas mit der Thematik befassen.

MH-Z19 Timeout in milliseconds: 20 ms gives a decent margin on top of the UART transmission time. The datasheet does not specify any timings beside the UART baud rate. A single byte takes 10 bits effectively: a start bit, 8 bits data and stop bit. 9 bytes are transmitted, thus 10 bits * 9 / 9600bps = ms. #define MHZ19_TIMEOUT_READ 20
