My aim is to hook up the Oak to the Voltcraft, parse the measurements and send ...

This mqtt sensor platform uses the MQTT message payload as the sensor value. If messages in this state_topic are published with RETAIN flag, the sensor will receive an instant update with last known value. Otherwise, the initial state will be undefined. Configuration. To use your MQTT sensor in your installation, add the following to your file:

Before we can use this formula in a sketch, we need to determine R0 of the MQ7 sensor first. This varies between devices so there is a need for actual testing. From the loglog plot, we can see that RS/R0 is constant in air and is equal to 1. Since by definition, R0 is the resistance of the sensor in clean air, then only RS varies for every gas.

For models featuring a CO2 sensor, the LED indicates carbon dioxide concentration (green = low concentration, red = high concentration). For variants lacking the CO2 functionality, the LED then indicates air quality index roughly equivalent to CO2 concentration. In all models, the LED has a secondary function of indicating wireless communication and device status.
