How to Control Humidity and Temperature on Your Room

In this Tutorial I will teach you about the Controlling of temperature In the lab, food storage plant, green house etc.

Some times we need a specific amount of temperature and humidity so we need a device that monitor the temperature and humidity in this project we make a prototype that will monitor temperature and humidity and display it on computer screen and we control the required temperature and humidity. In this system we use an AVR family micro controller(Arduino) interfaced with DTH11 temperature and humidity sensor. So here DTH11 measures both moisture and air temperature.Relative humidity, expressed as a percent, is the ratio of actual moisture in the air to the highest amount of moisture air at that temperature can hold.The warmer the air is, the more moisture it can hold, so relative humidity changes with fluctuations in temperature. And the entire data is show on serial monitor.

So now Be ready to learn How to interface  (DHT11) Sensor on Arduino. And for this we need to have some essential information about the components which we will use in this project.

What is DTH11 sensor ?

The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin. Its fairly simple to use.

DTH11 consist humidity and temperature sensor.

 

Components required

  • Arduino UNO
  • Connecting Wires
  • DTH11 Humidity and Temperature Sensor
  • DTH library

 

Step I

Firstly we need to include DTH11 library on ardiuno ide now we have to download the library file from this link

And add follow the simple step to include the library

Open arduino ide and click on skatch tab > include library > add Zip library > then choose your file

Step II

Now we have to connect dth11 sensor to arduino

How to Control Humidity and Temperature on Your Room

This is pin out of dth11

1 is Vcc

2 is data

3 no connection

4 ground

 

Connection

Connect pin 1 of dth11 to 5v of arduino

Connect pin 2 of dth11 to pin #5 of arduino

And connect pin 4 of dth11 to ground of arduino

Step III

Upload the program

Step IV

Now you can see the result on serial

So Friends I hope you understand this project . In upcoming Tutorial  I will back  with some more interesting Projects and will discuss about some useful development topics. And if you want to recommend that what I should write in upcoming Tutorial then please leave your comments. and if u need any help or query please don’t Hesitate to discuss with me. Thank You 🙂
