MH-Z19B - RevSpace

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.

MH-Z19 Teardown | MySensors Forum

Oct 03, 2017· I just wanted to share some information on the hardware of the popular MH-Z19 sensor. The software part is well covered in : MH-Z19 CO2 sensor and in particular in : MH-Z19.. As my sensor showed a discontinuous rise in CO2 concentration in my closed bedroom during a typical night (which is illogical) so I decided to open it.

mh-z19 - Python Package Health Analysis | Snyk

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.
