Story

Innovation Lab (170821)

Temperature and humidity were measured with temperature and humidity sensor.

Temperature and humidity values appear on the serial monitor.

The temperature was 28 and the humidity was 63.

Code

Temperature, Humidity Sensor

#include <DHT11.h>

DHT11 dht11(A0);
void setup()
{
  Serial.begin(9600);
}

void loop()
{
  float temp, humi;   
  int result = dht11.read(humi, temp); 

  if (result == 0) 
  {
    Serial.print("temperature:"); 
    Serial.print(temp); 
    Serial.print(" humidity:");
    Serial.print(humi); 
    Serial.println();
  }
  else
  {
    Serial.println();
    Serial.print("Error No :");
    Serial.print(result);
    Serial.println();
  }

  
  delay(DHT11_RETRY_DELAY);                         
}
