RY-GH Photosynthetic Active Radiation Par Sensor Rau Tsev Cog Khoom Nqe

Cov photosynthetically zoo hluav taws xob sensor yog tsuas yog siv los ntsuas cov photosynthetically zoo hluav taws xob ntawm lub teeb ntuj nyob rau hauv lub wavelength ntau ntawm 400-700nm, thiab yog yooj yim rau siv. Nws tuaj yeem txuas ncaj qha mus rau digital voltmeter lossis cov ntaub ntawv khaws cia thiab tuaj yeem siv nyob rau hauv txhua qhov huab cua puag ncig.The meter siv silicon photodetector thiab dhau los ntawm 400-700nm optical filter. Thaum muaj lub teeb, lub teeb liab hluav taws xob tsim tawm uas yog proportional rau qhov kev siv hluav taws xob ntawm qhov teeb meem hluav taws xob, thiab nws qhov rhiab heev yog proportional rau lub cosine ntawm lub kaum sab xis ntawm qhov teeb meem. μ • mol / m2 • s.Cov lus no yog siv dav hauv kev ua liaj ua teb meteorology thiab kev tshawb fawb qoob loo.
