Abstract
此研究之目的在於開發測試適用本省農業環境之日照計，並比較其各項性能。實驗結果顯示利用光二極體為感測元件的日照計其性能可合乎世界氣象組織之一級標準。利用Cds原理開發之感測器其誤差值偏高，其性能受到使用時期老化之影響。利用國產照度計改良而成之日照計其量測準確度約為20W／m2，持久性能十分穩定且成本低廉，此設備可適用於本省設施日照能量量測與控制作業。
The objectives of this research were to develop and test the performance of serveral pyranometers used in agricultural environment. The experimental results indicated that the accuracy of the Silicon Photovotatic cell pyranometers could compare well with the WMO standards for the first class instruments. The Cds-type solar meter has the higher error and serious aging problem. The accuracy of the INS-series meters that developed from the domestic LUX meter was nearly 20w/m2. The long-term stability was very well and the cost was inexpensive. It could serve as adequate pyranomenter to measure the solar energy and control the shading device for the protected culture in Taiwan.
