Brightness Transmitter 7.1414.61 measures daylight illumination intensity based on sun position.
The illumination intensity is acquired by three independent photodiodes arranged in 90-degree segments: East, South and West.
The electronics connected to the device convert light into voltage signals and provide them to the 3 individual outputs. The "heating" model prevents dew from forming on the dome.
