From the manufacturer's datasheet for Li65+ active.
Overview
The Li65+ measures illuminance outdoors, in greenhouses, warehouses and industrial halls. Its light sensor has an optical filter matched to the sensitivity of the human eye, and the range is selectable from six ranges between 0 to 200 lux and 0 to 50 klux. Depending on the part it also measures temperature, relative humidity and atmospheric pressure, and can calculate absolute humidity, enthalpy and dew point. Each measured value goes to its own analogue output: 0 to 10 V or 0 to 5 V on the voltage parts, 4 to 20 mA on the current parts. One part adds two relay outputs for a 2 point or 2 stage 2 point control. A hinged cover, tool-free wiring and removable cable entries speed up installation. Settings can be made with the USEapp or uConfig.
