2、要一種溫濕度具有成本低,使用方便、準確的監(jiān)測儀器控制。使用單片機對溫濕度掌控,具備精度高的可控的溫濕度、功效明顯、空間體積較小、價錢低輕易變通等長處達到了工藝。本論文經(jīng)過利用STC系列的單片機、1602液晶顯示器、DHT11的溫濕度傳感器和繼電器的掌控模塊,很容易的達到溫濕度的控制需要。DHT11傳感器把收集到的必要數(shù)據(jù)傳輸給單片機,通過單片機的處置,體現(xiàn)在液晶屏上。如果溫度超過設(shè)定值,將會驅(qū)動繼電器帶動負載工作。關(guān)鍵詞:溫濕度傳感器液品顯示器單片機智能控制AbstractModerntemperatureandhumiditycontrolhasbecomea
