本設(shè)計通過下位機(jī)和上位機(jī)結(jié)合來實(shí)現(xiàn)系統(tǒng)監(jiān)測的各項功能。上位機(jī)軟件使用Labview虛擬儀器進(jìn)行設(shè)計，下位機(jī)采用STM32F103C8T6單片機(jī)控制。下位機(jī)主要有溫濕度傳感器、光照傳感器、顯示器、無線傳輸模塊等組成。溫濕度傳感器可以采集室內(nèi)溫濕度，然后反饋給單片機(jī)，單片機(jī)處理后在顯示器上顯示相關(guān)參數(shù)。同時，光照傳感器的工作原理與溫濕度模塊相同。
1.上位機(jī)實(shí)現(xiàn)功能
通信波特率設(shè)置為115200，上位機(jī)通過USB無線串口轉(zhuǎn)NRF24L01模塊來接受下位機(jī)傳來的環(huán)境參數(shù)信息，實(shí)時顯示當(dāng)前溫濕度和光照強(qiáng)度，當(dāng)環(huán)境參數(shù)大于設(shè)定閾值時，上位機(jī)顯示界面中的報警指示燈亮起，同時下位機(jī)的蜂鳴器報警模塊會響起，啟動降溫模塊。當(dāng)環(huán)境參數(shù)回歸正常時，報警自動取消，降溫模塊停止工作。
2.下位機(jī)實(shí)現(xiàn)功能
單片機(jī)STM32F103C8T6通過DHT11溫濕度傳感器和光敏二極管分別采集當(dāng)前環(huán)境中的溫濕度和光強(qiáng)信息，通過OLED屏進(jìn)行實(shí)時顯示，并且將采集到的環(huán)境數(shù)據(jù)通過NRF24L01無線通信模塊實(shí)時發(fā)送至上位機(jī)端。當(dāng)環(huán)境參數(shù)大于設(shè)定閾值時，蜂鳴器模塊進(jìn)行報警，霧化器模塊進(jìn)行降溫處理。當(dāng)環(huán)境參數(shù)回歸正常時，報警自動取消，霧化器模塊停止工作。
