Tracking Air Quality with HDP and HDF: Part 2 - Indoor Air Quality

Using a few sensors on a MiniFi node we are able to generate some air quality sensor readings.

Source: https://github.com/tspannhw/minifi-breakoutgarden/blob/master/aqminifi.py

Data:

row['bme680_tempc'] = '{0:.2f}'.format(sensor.data.temperature)
row['bme680_tempf'] = '{0:.2f}'.format((sensor.data.temperature * 1.8) + 32)
row['bme680_pressure'] = '{0:.2f}'.format(sensor.data.pressure)
row['bme680_gas'] = '{0:.2f}'.format(gas)
row['bme680_humidity'] = '{0:.2f}'.format(hum)
row['bme680_air_quality_score'] = '{0:.2f}'.format(air_quality_score)
row['bme680_gas_baseline'] = '{0:.2f}'.format(gas_baseline)
row['bme680_hum_baseline'] = '{0:.2f}'.format(hum_baseline)
