MH-Z19C CO2 Sensor • ThingPulse

The MH-Z19C module is a next-generation CO2 sensor based on the non-dispersive infrared (NDIR) principle. MH-Z19 C is the successor of the widely popular MH-Z19 B. See below for a comparison. The MH-Z19C 400~2000ppm CO2 sensor has built-in temperature compensation and communicates over UART and PWM with the host controller.

arduino - MH-Z19 CO2 sensor giving diferent values using ...

09/10/2016· I have a MH-Z19 CO2 sensor, according the data-sheet I 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. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …

Read MH-Z19 CO2 meter to Domoticz using an arduino and ...

10/02/2018· Before we start messing with the ESP and connecting the MH-Z19 to the arduino, we need to create a dummy device to update the status to in Domoticz. In Domoticz go to Setup > Hardware and, if you don’t have one already, add the dummy hardware (1,2). And then click create a virtual switch. Now add a new virtual sensor, choose Custom Sensor as the Sensor Type. The name is up to you. Add …
