Humidity and temperature monitoring and controlling system

Project Title

Humidity and temperature monitoring and controlling system

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

Temperature and humidity are two of the most closely studied environmental factors since they have such a big influence on our lives.

Our project's goal is to create a humidifier and dehumidifier system that allows users to monitor and adjust temperature and humidity with a single integrated system. This system will automatically detect the temperature and humidity in your area or surroundings and then, it provides two options whether to humidify or dehumidify the air. When the air is dry, a humidifier will add moisture to the air and when the air has been humid, a dehumidifier will remove moisture from the space, restoring normal air pressure.

The software tools used in this project are:
Android Studio, Arduino IDE and the Java programming language is used to create the software.
 

For the construction of hardware we are using:
Arduino Uno, DHT-11Sensor, Hc-05 Bluetooth Module,
16*2 LCD, Spray and mist module.
 

This proposed system could provide a simple and effective approach for real-time temperature and humidity monitoring. When compared to the prices of devices used to measure environmental parameters, this system is compact and cost effective to some extent. Apart from this, humidifiers and dehumidifiers have health benefits as well as they can prevent dry skin, nose bleeds and asthma attacks.
 

In the future, this Arduino System can be made as an agriculture automation system. It will deliver precise information to farmers, pharmacists and others, allowing them to take proper measures.

Project Objectives

Our project's goal is to create a humidifier and dehumidifier system that allows users to monitor and adjust temperature and humidity with a single integrated system. This system will automatically detect the temperature and humidity in your area or surroundings and determine if the temperature is too high or too low. It can also help to control the level of humidity in the area, lowering the humidity or balancing the temperature. It provides two options for humidifying or dehumidifying the air. Humidity levels that are just right make your home seem cool in the summer and warm in the winter. When the air is dry, a humidifier will add moisture to the air, causing the temperature to return to normal and the humidity to automatically balance, whereas a dehumidifier will remove moisture from the space, causing the temperature to return to normal and the humidity to automatically balance.

Project Implementation Method

The whole software will be coded in the Java language where we will use SQLlite Database.The code will generate by Arduino IDE program and this program will go to Arduino Uno that will run the program. All the modules were designed and all the components assembled. The whole interface of the application was done Android application like register, login and home page. And all the data will store on SQL Lite The material of the hardware will join as follow that we will use Arduino Uno to interface with bread board, the jump wires, resistors are using to connect the material using breadboard DHT-11 sensor which connect with 0 pin of Arduino and Hc-05 Bluetooth module connect with 8 and 9 pins of Arduino module,16*2 LCD will attach with Arduino pins from 0-7. We have designed the whole circuit of the hardware but there is some problem which we are facing that how we connect spray module and mist module with bread board. We have actually find the groove button for using spray and mist module.

Benefits of the Project

Humidifier and dehumidifier are helpful in various places like industries, medical sectors and vehicles.
 

 Humidifiers are dehumidifiers are quite beneficial.
 

Advantages of humidifier:

• Prevent Dry Skin
   
• Relieve Dry Eyes
   
• Prevent Nose Bleeds
   
• Improve Hair and Scalp Healthy
   
• Protect Flooring and Furniture
   

Advantages of dehumidifier:

• Prevent Asthma Attacks
   
• Food Stays Fresh For Longer
   
• Lower Energy Costs
   
• Deter Insects

Technical Details of Final Deliverable

Software development tools
 

The software tools used in this project are:

• Android Studio: Android Studio is being utilized to create our user interface.
• Arduino IDE: The Arduino-Uno board is programmed using the Arduino software.
• Java language: The Java programming language is used to create the software.
   

Hardware development tools

For the construction of hardware we are using:

• Arduino Uno: which is the central hardware component of our system that controlled and managed all other parts.
• DHT-11 Sensor: that can detect the humidity and temperature and send the data to the database.
• Hc-05 Bluetooth Module: The HC-05 module is implemented in this project for Bluetooth communication.
• 16*2 LCD: a relatively simple module that may be found in avariety of devices and circuits.
• Spray and mist module: The spray is used if humidity is low and mist module is used if humidity is high.
