Cannot get MH-Z19B CO2 Sensor to Work - Programming ...

· 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 ...

arduino - MH-Z19 CO2 sensor giving diferent values using ...

· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· Introduction: In this article we will do a simple functional test of the MH-Z19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.
