bme680sensor
@/bme680sensor
IN@/bme680-device
Needs to connect with the self-ouput from the bme680-device node for initialisation
UPDpulse
Updates the pin
DONEpulse
Pulses 1 when the node has been executed
Gasnumber
Outputs the gas concentration (in kOhm)
Humiditynumber
Outputs the humidity (in %)
Pressurenumber
Outputs the environmental Pressure (in hPa)
Temperaturenumber
Outputs the temperature (in oC)
C++ implementation
