May 06, 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 ...

Jan 23, 2019· This package is ment to be used to read data from MH_Z19B CO2 Sensor via serial. Sensor can be bought on AliExpress for around 18€ (Jan 2019) It is recommended to disable Auto calibration and set measuring range to 5000 to get adequate readings after first day of use.
Apr 13, 2020· I tried to read the temperature and status, but it looks the MH-Z19B is not the same as MH-Z19 and returns always status zero and temperature looks maybe 10 degrees higher (so no value minus 40, but maybe value minus 50).

Dec 15, 2020· MH-Z19 / MH-Z19B ndir CO2 sensor for indoor air quality monitoring datasheet ( MH-Z19 / MH-Z19B) ガス：CO2; ：〜 V DC; ：[MHZ-19] < 18 mA , [MH-Z19B] < 20mA (@5V power supply) インターフェイスレベル： V (UART or PWM)
As stated in the datasheet, MH-Z19B should be kept away from heat. Experiment showed that the light sensor inside MH-Z19B stops working when MH-Z19B is exposed to an air stream from a heat gun. Interface. Sensor provides UART, PWM and analog output interfaces. Both PWM and analog output provide CO2 measurement result limited by some bounds.
Nov 05, 2018· Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off(MH-Z19B) are implemented at version or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 GAS, also MH-Z19B module.

MH - Z19 C02 gas sensor is a common type, small sensors, using the non-dispersive infrared (NDIR) principle to detection of our fleet in the air, has good selectivity, no oxygen dependence, long life, built-in temperature compensation: lotus digital output and waveform output at the same time, easy to use.
My experiences with the MH-Z19 NDIR CO2 sensor Warning: I just destroyed my MH-Z19 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 ...
