Aurolex can monitor light intensity. For this purpose a lux sensor that meets the requirements of NEN-1891, Class A or B of the DIN 5032, Part 7 is connected to the Aurolex. t Measured values are continuously monitored and readings are sent to the Aurolex server. If the vertical illumination is measured by the sensor NSVV directive is being used in an enclosure in order to limit to 150 graden.De Dutch guidelines NSVV concerning light pollution consist of the following parts of the incident light beam:
. Lichthinder Part-1 "General Limit Sports Lighting"
