Paper 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 400nm-700nm, 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, a type of multi-channel quantum sensor is designed to solve this problem. Firstly, the paper expounds the design principle, circuit and structure of the sensor, and calibrate the unregulated sensors by the PQS-1 sensor under the calibration device constructed by controller based on DMX512 protocol. The test results show that the sensor has good linear response, whose average R2 is 0.9956. 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.
