Arduino Mega with DHT11

Other Hardware Sensors

Sorry, I can't seem to find out how to search the forum for this topic. I can't seem to find a working library for a DHT11 sensor and Arduino Mega. Any help will be appreciated.
Thanks

Google: Arduino DHT11 or go to your Library Manager, write DHT11 and you will find many options. Choose DHT Sensor Library for instance.

The libraries I have found give me an error , "Error compiling for board for Arduino Mega".
Any other suggestions?
Thanks

Sure - post your code, and include a link to where you got any libraries you are using.
Attach as an .ino file works best, unless it's very short.

The following sketch works well with MEGA+dht11 + the attached Library.

#include "DHT.h"
#define DHTPIN 8          // what digital pin we're connected to
#define DHTTYPE DHT11     // DHT11
DHT dht(DHTPIN, DHTTYPE);

void setup() 
{
  Serial.begin(9600);
  dht.begin();
}

void loop()
{
  delay(2000);
  float humi = dht.readHumidity();
  float tempC = dht.readTemperature();
  float tempF = dht.readTemperature(true);

  if (isnan(humi) || isnan(tempC) || isnan(tempF))
  {
    Serial.println("Failed to read from DHT sensor!");
    return;
  }

  Serial.print("Humidity: ");Serial.print(humi);Serial.print(" %\t");
  Serial.print("Temperature: ");
  Serial.print(tempC);Serial.print(" *C ");
  Serial.print(tempF);Serial.println(" *F");
}
