描述

我需要檢查空調房的確切溫度，以顯示空調房與遙控器上顯示的不一樣。所以我決定做這個。

您將需要 x1 面包板（可選）

x1 套電線

x1 dhtxx

x1 Arduino uno

所以連接（從左到右）

引腳 1 至 5v

引腳 2 到數字引腳 7

引腳 3（留下它）

引腳 4 接地

它將以 C、F、K 和濕度顯示

這里的代碼

謝謝

//Libraries
#include ;
//#include:
//Constants
#define DHTPIN 7     // what pin we're connected to
#define DHTTYPE DHT22   // DHT 22  (AM2302)
DHT dht(DHTPIN, DHTTYPE); //// Initialize DHT sensor for normal 16mhz Arduino
//Variables
int chk;
float hum;  //Stores humidity value
float temp; //Stores temperature value
float faran;
float kel;
void setup()
{
 Serial.begin(9600);
 dht.begin();
}
void loop()
{
   delay(2000);
   //Read data and store it to variables hum and temp
   hum = dht.readHumidity();
   temp= dht.readTemperature();
   //Print temp and humidity values to serial monitor
   Serial.print("Humidity : ");
   Serial.print(hum);
   Serial.println(" %");
   Serial.print("Temp     :");
   Serial.print(temp);
   Serial.println(" Celsius");
   faran = (temp * 9.0) / 5.0 + 32;
   Serial.print("Faranheit: ");
   Serial.print(faran);
   Serial.println(" F");
   kel = temp + 273.15;
   Serial.print("Kelvin: ");
   Serial.print(kel);
   Serial.println(" K");
   Serial.println("");
   Serial.println("");
   delay(5000); //Delay 5 sec
