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

2018-02-10· 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 …

Mh Z19 - For Arduino Boards (&ESP32). Additional Examples ...

Advice: The MH-Z19 works best in the Range of 2000ppm, outside of this accuracy begins to fall away. This is supported by documentation by also by features such as the Analog Out. I would suggest keeping to this range if you need accuracy and a maximum of 5000ppm. Relevant Datasheets. The Englisih datasheet for the MH-Z19: MH-Z19. The English datasheet for the non-JST MH-Z19B version: MH …

drivers/mhz19/include/mhz19_ File Reference

MH-Z19 Buffer size: A transmission from the MH-Z19 is 9 bytes long: 1 Start byte 1 Sensor number 2 bytes data 4 bytes padding 1 byte checksum. The start byte is not stored because it is not used in the checksum calculation. #define MHZ19_BUF_SIZE 8 MH-Z19 Timeout in milliseconds: 20 ms gives a decent margin on top of the UART transmission time. The datasheet does not specify any timings …
