Efficient and simple DHT library

craigcurtin · June 14, 2013, 5:02am

I've written a library for reading out the DHT family of temperature/humidity sensors with the following features:

Support for DHT11 and DHT22, AM2302, RHT03

Auto detect sensor model

Low memory footprint

Very small code base

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());
}

I liked writing it - perhaps useful for someone else...

Thanks Very much for this - i was just about implement my first one of these so will give it a whirl and report back !

regards

Craig
