STM32環(huán)境檢測(cè)系統(tǒng)設(shè)計(jì) 可顯示PM2.5及溫濕度

ID:198608 · 發(fā)表于 2017-10-20 21:51

采用dht11溫濕度傳感器，和pm2.5傳感器，用tft液晶屏顯示
做出來(lái)的實(shí)物圖：

單片機(jī)源程序如下:

#include "lcd.h"
#include "usart.h"
#include "led.h"
#include "dht11.h"
#include "ds18b20.h"
#include "adc.h"
unsigned char hjjc[72*6] = // ASCII
