Luminosity Measurement
The RP Series expansion multi-sensor supports luminosity measurements through an ambient light sensor.
The ambient light sensor measures the intensity of visible light. The spectral response of the sensor matches the response of the human eye. The sensor's luminosity range is 0 to 10,000 lux.
The sensor's field of view is 30 degrees from vertical.
It is recommended to install the multi-sensor at least 1 m (3.3 ft) from all windows to help prevent strong sunlight from disturbing the sensor's luminosity measurements.
The multi-sensor luminosity measurements need to be calibrated on site during commissioning. The calibration is done by measuring the light levels in the room using a light meter and then entering a constant lighting reference value (lux) in the EcoStruxure Building Operation software. 有关更多信息，请参阅 Configuring the RP Series Expansion Multi-sensor Ambient Light Sensor .
