Abstract：The measurement of plant growth's luminous environment is the basis of urban agriculture,such as LED plant factory.The PAR quantum sensors,which measure the photon flux of radiation in the spectral interval 400 ～ 700 nm,can't measure the several intervals which are used in plant lighting simultaneously,but the LED plant factory needs these data and their ratios by far.Therefore,a type of multi-channel quantum sensor is designed to solve this problem.Firstly,the paper expounds the design principle and structure of the sensor.It then elicits the calibration coefficient expression of the sensor's different channels,and calibrates the unregulated sensors by the PQS-1 sensor under the calibration device constructed by controller based on DMX512 protocol.Results indicate that the linear response of sensors is good.The article finally designs a set of light environment control system,which can auto control the photon fluxes and light quality ratios,based on the sensors.
