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

06/05/2021· 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 ...

Infrared CO2 module MH-Z19B Module interfacing with ...

In this project we are using MH-Z19B Infrared Co 2 Module. We 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. You can see the output on the serial monitor
