全數(shù)字測溫濕及光照系統(tǒng)的研制

根據(jù)農(nóng)業(yè)生產(chǎn)特點, 以“成本低、高品化、微型化、低功耗、長壽命、高可靠性”為原則, 研制了集4 參數(shù)(溫度、濕度、光照和雨量) 為一體的全數(shù)字農(nóng)業(yè)環(huán)境數(shù)據(jù)采集系統(tǒng)。該系統(tǒng)選用全數(shù)字傳感器,并附加有通信接口, 能多點測量溫度、濕度和光照, 性能可靠, 誤差小。

Abstract : According to the characters of agriculture that are the low investment , miniaturizing , low ex2 hausting , high reliability , and long life , the authors develop the digital data collection system of agri2 culture environment information , which integrates the parameters such as temperature , humidity , and illumination. It adopts direct at digital transducers and has communication interface. It can measure temperature , humidity and illumination of diferent sites with high accuracy and discrimination.
