Cannot get MHZ19B CO2 Sensor to Work Arduino Forum

+

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 ...

In this project we are using MHZ19B 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 05000ppm, and via PWM I should have readings between 02000ppm. You can see the output on the serial monitor

My experiences with the MHZ19 NDIR CO2 sensor Warning: I just destroyed my MHZ19 sensor when soldering, I was changing connectors with lead free solder, iron set to 380 C. I had to heat for a little while to remove the old header. Now the sensor only gives a very low value, both on PWM and serial output. Before destroying the device, I was getting strange values around 900 ppm when I should ...
