  • Temperature and humidity module for Arduino KY-015

    Temperature and humidity module for Arduino KY-015

    What is the KY-015 DHT11 Module?

    The KY015 is a temperature and humidity module for Arduino and other microcontroller projects

     

    KY-015 module has a DHT11digital temperature and humidity sensor and a resistor. The DHT11 uses a thermistor for the temperature sensing and a capacitive humidity sensor along with an internal IC to give a digital output for both temperature and humidity.

     

    Voltage : 3.3 to 5VDC

    Humidity range : 20% to 90% @ 5% RH accuracy

    Temperature range : 0C to 50C at 2C accuracy

    Size 30x15mm

     

    How Can I use the KY-015 Module to monitor temperature and humidity?

    Here is an example project to measure temperature and humidity using the KY015 module and an Arduino Uno

     

    Temperature and Humidity Sensor

    In this project, we will be building a weather station that can measure both temperature and humidity.

    This is what you will need:

    Tools

    Jumper Leads (male to female)

     

    Components

    Arduino Uno x 1 or Arduino Nano x 1

    KY-15 sensor module

     

    Libraries

    DHT Sensor Library

    Adafruit Unified Sensor Library

     

    Step 1

    First you will nedd to assemble the project. Connect everything together using the wiring diagram bellow for reference.

     

     

    Connect the KY-015 sensor module to the Arduino

    KY-015                        Arduino   

    Ground - - - - - - - - - -  Ground
    Vcc - - - - - - - - - - - - - - 3v3
    Data - - - - - - - - - - - - -  A0

    A 10KΩ pull-up resistor is built in to the KY-015

     

    Step 2

    Connect your Arduino to the PC and install the above Libraries. If you don’t know how to do this, CLICK HERE and follow the “Installing Arduino Libraries” section.

     

    Step 3

    We can now create the code to get this all working

    First, delete the code in the IDE window, then include the aforementioned libraries:  

    #include "DHT.h"

    This bit of code imports the DHT library and links it to the sketch.

    #define DHTPIN A0
    #define DHTTYPE DHT11

    This bit of code defines which pin is KY015 connected to and sets the type of sensor (KY015 uses DHT11)

    DHT dht(DHTPIN, DHTTYPE);

    This bit of code initialises the sensor

    void setup() {
      Serial.begin(115200);
      Serial.println(F("DHT11 test!"));
      dht.begin();
    }

    The setup bit of code initialises serial output with baud rate of 115200 and prints DHT11 test! In the console

    void loop() {
       delay(2000);

    This bit makes the Arduino wait 2 seconds between measurements

      float h = dht.readHumidity();

    Read humidity from the sensor

      float t = dht.readTemperature();
    Read temperature from the sensor
      Serial.print(F("Humidity: "));
      Serial.print(h);
      Serial.print(F("%  Temperature: "));
      Serial.print(t);
      Serial.println(F("°C "));
    }

    Print the latest reading in serial monitor

     

    Finished Code:

    #include "DHT.h"
    
    #define DHTPIN A0 // Digital pin connected to the DHT sensor
    #define DHTTYPE DHT11 // DHT 11
    DHT dht(DHTPIN, DHTTYPE);
    
    void setup() {
      Serial.begin(115200);
      Serial.println(F("DHT11 test!"));
    
      dht.begin();
    }
    
    void loop() {
      delay(2000);
    
      float h = dht.readHumidity();
      float t = dht.readTemperature();
    
      Serial.print(F("Humidity: "));
      Serial.print(h);
      Serial.print(F("%  Temperature: "));
      Serial.print(t);
      Serial.println(F("°C "));
    }
