An Arduino library for reading the DHT family of temperature and humidity sensors.
Written by Mark Ruys, [email protected].
- Support for DHT11 and DHT22, AM2302, RHT03
- Auto detect sensor model
- Low memory footprint
- Very small code
#include "DHT.h"
DHT dht;
void setup()
{
Serial.begin(9600);
dht.setup(2); // data pin 2
}
void loop()
{
delay(dht.getMinimumSamplingPeriod());
Serial.print(dht.getHumidity());
Serial.print("\t");
Serial.print(dht.getTemperature());
}
Also check out the example how to read out your sensor. For all the options, see dht.h.
Place the DHT library folder in your <arduinosketchfolder>/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the Arduino IDE.
