【Abstract】: Environmental control has always been the most important part of agriculture. For agricultural production, temperature and humidity play a decisive role, especially in agricultural production. Temperature and humidity monitoring plays an important role in improving the quantity of products, saving resources and safety in production. In order to improve the quantity of products and maximize the utilization of raw materials, to ensure a more suitable living environment for agricultural products, accurate measurement of temperature and humidity has attracted the attention of various industries. To solve this problem, this paper designs a farmland temperature and humidity monitoring system based on 52 single chip computer. The system uses AT89C52 MCU and its peripheral circuit as the main control circuit, and STH11 temperature and humidity sensor as the detection element to detect soil moisture, temperature and humidity in farmland. It realizes efficient and economical automatic monitoring, and has good application value.
【Key words】: 52 MCU; Temperature and humidity sensor; Temperature and humidity automatic monitoring system
0 ?引言
眾所周知,我國(guó)是農(nóng)業(yè)大國(guó),環(huán)境控制一直都是農(nóng)業(yè)里面最重要的一部分,對(duì)于農(nóng)業(yè)生產(chǎn)而言,溫度和濕度對(duì)其有著決定性的作用,不同農(nóng)作物所需的生長(zhǎng)環(huán)境不同,同種農(nóng)作物不同時(shí)期所需要的生長(zhǎng)環(huán)境也是不一樣的,未來(lái),農(nóng)業(yè)發(fā)展方向一定是向科技化,機(jī)械化方向邁進(jìn),加強(qiáng)信息技術(shù)的研發(fā)和應(yīng)用以提高生產(chǎn)率,降低成本[1-2]。同時(shí),適宜的溫度和濕度是農(nóng)作物生存及生長(zhǎng)發(fā)育的重要條件之一,不僅影響著作物的發(fā)育速度,同時(shí)對(duì)作物的生長(zhǎng)以及產(chǎn)量有著直接影響,因此,溫濕度的監(jiān)測(cè)對(duì)農(nóng)業(yè)生產(chǎn)是至關(guān)重要的。……
