project for connecting CO2 sensor mzh19 to orangePI or similar boards via COM port
The project https://www.circuits.dk/testing-mh-z19-ndir-co2-sensor-module/ was taken as a basis, the script of which was brought to working form
there are 3 scripts in the set
mhz19.py working script from the first example outputs data to console and also writes to CSV file.
mzh19MQ.py script transfers sensor data to the MQTT bus, for example, for data collection by a smart home
mhz19MQ_CSV.py transfers sensor data both to the MQTT bus and to a CSV file
In all scripts it is necessary to specify the name of the port to which the sensor is connected.
port = '/dev/ttyS0'
