IoT Base Temperature And Relative Humidity Monitoring System

ABSTRACT

It was discovered that virus such as COVID-19 propagates rapidly in cold temperature and humidity. Many people are conscious about the environment they are living in. In order to help those people a smart environment monitoring system is needed. A smart Internet of Things (IoT) based temperature and humidity real time monitoring and reporting system is an effective system that is equipped with temperature sensor and relative humidity sensors for taking measurement. The proposed system is an advanced solution for monitoring and live reporting the temperature and humidity at different points in specific locations. The real time data from these sensors are stored in cloud server and email is sent to the predefined recipients to let them access the data remotely over internet. When the measurement of temperature and humidity reaches over safe level then the recipients can take immediate action to alert people to be careful about corona virus. The proposed system is designed based on Arduino UNO Board, temperature sensor DHT11, humidity sensor, ESP8266 Wi-Fi module, IoT, DC-DC modular, and solar panel. The main characteristics of this proposed system is low cost, low power consumption because of self-powered device, high accuracy and user friendly. The system shows a high degree of accuracy and reliability.

1.1                                                     BACKGROUND OF THE STUDY

Keeping an eye on the ideal temperature and humidity levels in a classroom is essential. Sudden changes in the weather can impact the health of both the students and teachers.

Therefore, It is important for us to understand the advantages of maintaining/controlling an ideal temperature in order to make a suitable environment for learning.

In this time and day, everything can be monitored and controlled automatically. Unfortunately, in an important sector like Education, the automatic monitoring of  physics lecture halls is very important, especially when it comes to prevention of sicknesses and diseases such as COVID-19.

In COVID-19 pandemic period, environmental concern including temperature and humidity variations are becoming an important topic. The random variation of temperature and humidity caused by greenhouse effect has impact on propagation of corona virus. These unwanted changes are driving to develop of environment monitoring system especially for temperature and humidity [1]. This paper focuses an IoT based system that effectively monitor the variation in temperature          and     humidity using        sensors, microcontroller, and IoT based technologies. This makes our system more reliable as if one of the nodes is not working properly or been damaged somehow than the other one will begin to function or activate dynamically. Wireless communications are used to collect data and to communicate between the centralized control center and the actuators located at different locations within a specified area [3].In this proposed system, the data collected from different nodes are stored in cloud server and then sent to the recipient through email.

1.2                                                           PROBLEM STATEMENT

In COVID-19 pandemic period, corona virus propagates rapidly in cold temperature and humidity. Many people are conscious about the environment they are living in even in our schools. In order to help those people a smart environment monitoring system is needed. The proposed system was built to monitor physics classroom temperature and relative humidity.

1.3                                               AIM AND OBJECTIVE OF THE STUDY

The main aim of this work is to create an effective and healthy learning environment by automatically monitor the relative humidity and temperature of a physics hall using internet of things. The objectives are:

1. To monitor relative humidity and temperature wirelessly
2. To build a device that monitors relative humidity and temperature wirelessly

• To reduce human labour.

1. To ensure that students and teachers are happy, healthy and comfortable

1.4                                           SCOPE AND LIMITATION OF THE STUDY

The scope of this work covers wireless monitoring of temperature and relative humidity of a physics class room. The proposed system incorporates various sensors such as temperature sensor and humidity sensor to collect possible environmental parameters of the environment as well as integrate Arduino Uno. It is accomplished by the data communications between Arduino, DHT11 Sensor Module, ESP8266 WIFI module and LCD. Celsius scale thermometer and percentage scale humidity meter displays the ambient temperature and humidity through a LCD display.

1.5                                               SIGNIFICANCE OF THE STUDY

The building and application of this device in our classroom shall serve as a means of maintaining and ensuring happy, healthy and comfortable learning and teaching environment for both students and lecturers.

Also, this study will serve as a medium of exposing us to the application of IoT and integration of arduino with DHT11 Sensor Module, ESP8266 WIFI module and LCD.
