MH-Z19 AUTU Kalibrasyonu

drivers/mhz19/include/mhz19_ File Reference

MHZ19 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
