From the manufacturer's datasheet for Li65+ RS485 Modbus.
Overview
The Li65+ measures light level outdoors, in greenhouses, warehouses and industrial halls. It has a light sensor with an optical filter matched to the sensitivity of the human eye. Versions add temperature, humidity and atmospheric pressure, and humidity can be given as relative humidity, absolute humidity, enthalpy or dew point. It has a Modbus RTU interface and 0 to 10 V or 0 to 5 V outputs, and a two-stage relay option for a two-point controller. Light is measured in six selectable ranges, from 0 to 200 lux up to 0 to 50 klux.
