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 ...
