Application the five photosynthetic reactions of plants, including photosynthesis, pigment synthesis, photoperiodicity, phototaxis and morphological mutation, all happen in the wavelength range of 400700nm. Thus the wavelength in 400 700nm of radiation is called photosynthetically active radiation (par), its symbol is qp and its unit is wm2. Par is the energy source of the plant life activities, organic matter synthesis and yield formation.Features gps coordination can be recordedrecord data automatically or manuallywireless data transmission via wi-firecognize sensors by two-dimensional codeautomatically recognize connected sensorsterminal memory card is up to 32gdisplay real-time data and curve of recorded dataexport data to excel for analysis technical parameters sq200
