blockBrightnessMeasurementRoom

Sensor function to retrieve room illuminance from physical sensor

Extends from Interfaces.Partial.PartialFunction (Superclass for all function blocks to provide graphics and enforce implementation of functionality).

Information

Overview

Block that implements function "Brightness measurement" from VDI 3813 [1, section 6.1.6, p. 14]. For semantic correctness it is specialized for indoor illuminance.

Functional Description

"The function Brightness measurement (RA-FL section 2, column 5; informative function block Figure 7) is required for measuring the illuminance in rooms as well as for determining the illuminance of daylight. The former is used for lighting functions, whereas the intensity of daylight influences particularly the sunshading functions." [1, section 6.1.6, p. 14]
