===
|
|
|
|
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());
|
|
}
|
|
```
|
|
Also check out the [example] how to read out your sensor. For all the options, see [dht.h][header].

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.
