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());
|
||||
}
|
||||
```
|
||||
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.
