EASY plug DHT11 Temperature and Humidity Sensor

Introduction

This DHT11 Temperature and Humidity Sensor features a digital temperature and humidity sensor complex with a calibrated digital signal output. It can detect temperature and humidity of the surroundings. It has excellent quality, fast response, anti-interference ability and high cost performance advantages.
Note: this module needs to be used together with EASY plug control board.

Sample Code

#include <dht11.h>
dht11 DHT;
#define DHT11_PIN 10 
void setup(){
 Serial.begin(9600);
 Serial.println("DHT TEST PROGRAM ");
 Serial.print("LIBRARY VERSION: ");
 Serial.println(DHT11LIB_VERSION);
 Serial.println();
 Serial.println("Type,\tstatus,\tHumidity (%),\tTemperature (C)");
}
void loop(){
 int chk;
 Serial.print("DHT11, \t");
 chk = DHT.read(DHT11_PIN);    // READ DATA
 switch (chk){
   case DHTLIB_OK:  
               Serial.print("OK,\t");
               break;
   case DHTLIB_ERROR_CHECKSUM:
               Serial.print("Checksum error,\t");
               break;
   case DHTLIB_ERROR_TIMEOUT:
               Serial.print("Time out error,\t");
               break;
   default:
               Serial.print("Unknown error,\t");
               break;
 }
// DISPLAT DATA
 Serial.print(DHT.humidity,1);
 Serial.print(",\t");
 Serial.println(DHT.temperature,1);
 delay(1000);
}
