Illuminance
The illuminance sensor measures the value of light intensity, which is used to determine if there is a
proper amount of light in the room.
Figure 6 Example of illuminance monitoring chart.
CO2sensor
The CO2level is a critical indoor environment parameter because it affects human health. For
example, high levels within a short duration can reduce concentration and increase heart rate.
