May 06, 2021· Hi there everyone, I’m new this this forum and fairly new to Arduino. I’m having and issue getting my MHZ19B CO2 sensor to read in my serial monitor. I’ve tried looking at many different examples of code that others have posted in their success stories. When I open my serial monitor, all I see is that the sensor is preheating. Nothing after that. The sensor needs about 3 minutes to heat ...

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
