This is a simple example of how to use the HobbyComponents Arduino DHT11 module (HCARDU0020). The module will work with the Arduino DHT11 library available at http://arduino.cc/playground/Main/DHT11Lib without any modification. This code demonstrates the use of this library to output the current temperature and humidity measured by the sensor.
You may copy, alter and reuse this code in any way you like but please leave reference to HobbyComponents.com in your comments if you redistribute this code. */
/* Include the DHT11 library available at http://arduino.cc/playground/Main/DHT11Lib */
#include <dht11.h>
dht11 DHT11;
/* Define the DIO pin that will be used to communicate with the sensor */
#define DHT11_DIO 2
void setup()
{
/* Setup the serial port for displaying the output of the sensor */
Serial.begin(9600);
}
/* Main program loop */ void loop()
{
/* Perform a read of the sensor and check if data was read OK */
if (DHT11.read(DHT11_DIO) == DHTLIB_OK)
{
/* If so then output the current temperature and humidity to the serial port */
Serial.print("Temperature: ");
Serial.print((float)DHT11.temperature, 2);
Serial.print("oC\t");
Serial.print("Humidity: ");
Serial.print((float)DHT11.humidity, 2);
Serial.println("%");
}else
{
/* If there was a problem reading from then sensor then output an error */
Serial.println("ERROR");
