DHT
===

An Arduino library for reading the DHT family of temperature and humidity sensors.

Written by Mark Ruys, <mark@paracas.nl>.

Features
--------
  - Support for DHT11 and DHT22, AM2302, RHT03
  - Auto detect sensor model
  - Low memory footprint
  - Very small code

Usage
-----

```
#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());
}
```

Installation
------------

Place the [DHT][download] library folder in your `<arduinosketchfolder>/libraries/` folder. You may need to create the `libraries` subfolder if its your first library. Restart the Arduino IDE.
