? 這次的設(shè)計(jì)主要是通過讀取DHT11和HCSR04的數(shù)值，（Proteus的傳感器貌似這兩款好用一點(diǎn)）把讀取的DHT11和HCSR04數(shù)值通過轉(zhuǎn)化在lcd1602中顯示出來，還有就是可以設(shè)置通過按鍵設(shè)置DHT11的溫濕度閾值。

仿真原理圖如下

按下K1，K2為加1設(shè)置，K3為減1設(shè)置

?濕度低于88%；警報(bào)響，紅燈亮

程序展示：

unsigned char t0 = 0X32,t1 = 0X38;
unsigned char DATA[4];//存溫濕度數(shù)據(jù)

可以自己按照這個(gè)思路進(jìn)行自行設(shè)計(jì)，也可以通過百度網(wǎng)盤列表下載已經(jīng)做好的 https://www.aiesst.cn/share.html
