Sketch to Read DHT11 Sensor
and send results to the serial monitor
#include <dht.h> //include DHT11 library
int temp_humid_pin = A0; //define pin used for DHT11 reading
dht sensor; //define variable to reference sensor
void setup()
{
}
void loop()
{
delay(9000); //pause before reading sensor
sensor.read11(temp_humid_pin); // read sensor
Serial.print("Humidity ");
Serial.println(sensor.humidity); //print to serial monitor also
Serial.print("Temperature ");
Serial.println(sensor.temperature); //print to serial monitor also
}
