Cannot get MH-Z19B CO2 Sensor to Work - Arduino Forum

2021-05-06· Hi there everyone, I’m new this this forum and fairly new to Arduino. I’m having and issue getting my MH-Z19B 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 ...

java - Parsing data read from multiple sensors on Arduino ...

2013-04-26· If the Arduino is simply sending the temperature back as a string from each sensor in sequence (I assume it is but you haven't specified what it's sending at all, so I could be wrong) then assuming you haven't disabled reset on serial connect, you could simply take note of the order the temperatures come in at - say the first temperature read is from sensor 1, the second from sensor 2, …
