The Internet of Things (IoT) contributed to developing new concepts of monitoring and control systems for Air Handling Units (AHU). This paper proposes a modification of the traditional temperature monitoring and controlling system in AHU to a system based on the principles of the IoT. This is to take advantage of the features and characteristics of the Internet of things in accessing the system, following it up, and modifying it, Also evaluate the extent of reliance on software instead of hardware if the physical controller is replaced with a cloud controller in terms of data transfer rate and security of communication between the controller and field devices. The proposed system is applied to a real AHU. In the proposed system, the existing traditional temperature sensor and actuator are modified to be connected to the internet. With this modification, data can be received and sent with the IoT platform. So, the physical controller is replaced by a cloud controller on the IoT platform to receive the sensor readings and send the control signals to the actuator. Moreover, it configures a temperature alarm mails system to be sent to the authorized people in case of the temperature value is out of limits. The proposed system gives remote access to display the temperature readings and the controller’s output. Thus, the performance of the system can be monitored with the ability to modify the controller to suit the system’s needs. 03 30 2022 108 113 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.F6861.0310622 https://www.ijrte.org/portfolio-item/f68610310622/ Department of Computers Science and Information System. Taibah University, Al Madinah Almunawara, Saudi Arabia. Waseem Alromema Coronavirus pandemic has created complex challenges and adverse conditions. Sentiment analysis is a process of studying the user application. Because of using the internet in daily activities, many domains and organizations concentrate on analysis or getting user feedback to take the right decision. This paper is review the existing applications that used a sentiments analysis to identify major sentiment trends associated with the push to reopen the analyzing sentiment in social media like Twitter, etc. Data time aligned to the COVID-19 reopening debate. In addition, discover the most popular techniques and approaches. This study focus the research articles in high impact journals that published during the epidemics from 2019 to 2021. The research question that this study answer it are. This study can be beneficial to many domains such as sentiment analysis, text mining, research in related areas, and postgraduate students. This research could present valuable time sensitive opportunities for governments, and the nation into a successful new normal future. Several applications have employed in several domains, including tourism, education, business and health. Health information can be disseminated by social media and misinformation can be addressed via this platform. 03 30 2022 114 118 CC BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijrte.org true 10.35940/ijrte.F6855.0310622 https://www.ijrte.org/portfolio-item/f68550310622/
