Read MHZ19 CO2 meter to Domoticz using an arduino and ...

20180210· Before we start messing with the ESP and connecting the MHZ19 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 …

However I found a reasonably priced sensor for free in the Winsen MHZ19 when I was scavenging an AC unit for parts. The MHZ14, MHZ16 and MHZ18 are also useable. But I understand the MHZ18 is quite expensive (92 euro''s at aliexpress). The MHZ16 and MHZ19 are both about 2530 euro. The MHZ19 has 3 ways of reading the CO2 concentration. It has a Tx/Rx UART, It has an analog output and it ...
