Abstract：Photosynthetic active radiation sensors only response to the light between 400nm~700nm.The red light quantum and blue light quantum cannot be identified directly for LED light.In this paper, a multi-channel photosynthetic active radiation sensor which has a narrow-band spectral response matching with plant absorption peak is proposed.The red light and the blue light are measured with quantum density directly.It can be applied to plant factory with low cost and portable.It is also easy to create sensor network, collect the plant growth light recipe data and realize intelligent control of light.This sensor can play a key role on the plant light recipe accumulation and the energy consumption reduction for plant factory.
