Hi

This question is regarding the actual control sensor that will be used in a
building.
So in equest for switchable windows, I am using solar radiation as trigger
point to control the switching of windows.
am getting good savings and now I want to use that same data to operate the
control system in the building.
so if my windows change state based on intensity of solar radiation, which
sensor is used to give signal to control system which will measure the solar
radiation intensity in W/sq.m
where is this sensor placed in building layout.
does anyone have experience in applying the sensor control to actual
building project?
thanks for the help
