This page can plot/view live data + historical data.
Click on checkbox or text to show data plot.
The plots show 100 data points by default.You can plot more historical data by selecting period. It takes longer to load data without hourly average.
Depending on the update frequency of the data, the plots show data points at successive intervals of time:
- Battery/PV: 90 seconds
- dht22 and bme680: 15 minutes
Current in amps
Voltage in Volt
Instantaneous power
Instantaneous power 1
Panel power in Watt
Total yield
MPPT state: 0 = off; 1 = Voltage of current limited, 2: MPP tracker active
Light index based on value read from sensor, varies from 0 to 4000
Air quality
Estimates a CO2-equivalent (CO2eq) concentration [ppm] in the environment. It is also calculated based on the sIAQ output and derived from VOC measurements and correlation from field studies.
Besides ethanol (EtOH) as a target test gas, the sensors are also tested with breath-VOC (b-VOC). The b-VOC mixture, as
listed in Table 5 (datasheet), represents the most important compounds in an exhaled breath of healthy humans. The values are derived
from several publications on breath analysis studies. The composition does not contain species which would chemically react
to ensure that the mixture is stable for at least 6 months. Furthermore, the composition is also limited to species which can
be manufactured in one mixture.
