Early fire detection system in tanzania markets
(MDPI, 2020-11-14) Hilary, Rambo; Rotich, Philemon; Geofrey, Anna; Sam, Anael
Application of wireless sensor networks (WSN) and Internet of Things (IoT) used to provide real-time monitoring of fire outbreak in markets. The system integrates three subsystems namely; sensing subsystem which uses multiple sensors for detecting fire outbreaks. Data processing subsystem which collects data from the sensing subsystem through Xbee, analyses, and uploads data to the cloud. If values exceed the sensor threshold, an alarm is triggered and notification is sent to stakeholders via mobile application subsystem. The integration between sensing, data processing, and mobile application subsystems pave a new way for the mitigation of fire outbreaks at its early stage.
Mobile Application for Gate Pass Management System Enhancement
(IEEE, 2021-09-15) Hilary, Rambo; Machuve, Dina; Mirau, Silas
Gate pass management is a vital measure to keep records of people’s entrance and exit of company premises. Technological improvement steered gate pass management from paper-based logbooks to web-based systems that rely on the internet. Usually, a web-based system can be accessed through a computer browser or mobile browser. The technological evolution of smartphones lures many users in using mobile phones for access internet and web-based systems. The use of smart phone offers portability, flexibility, and a good user experience. Due to the small screen size and input method of smartphones, it’s challenging to use mobile phones to access web-based gate pass management systems. The development of mobile applications introduces a better user experience and easy access to gate pass users. The application provides added advantage in simplifying the whole process of gate pass management. Mobile phone portability and accessibility are utilized to ensure users can have access to gate pass management at any time and anywhere. Mobile application camera is an added feature utilized for scanning gate pass barcodes and taking pictures of gate pass users for more security records. Therefore, the enhancement of the gate pass management system brings an easy way for the user to manage the gate pass process through their smartphone phones.
Mobile application for gate pass management system enhancement
(NM-AIST, 2022-02) Hilary, Rambo
Gate pass management is an essential measure to keep records of people's entrance and exit of company premises. Technological improvement steered gate pass management from paper-based logbooks to a web-based system that relies on the internet. The web-based system contains forms to input personal information, exit and entry time, and reason for requesting a gate pass. For a large organization with a diverse number of employees who do not have access to computers for their daily routine activities, it’s extremely challenging to request a gate pass through an existing web based gate pass management system. Thus, users turn to smartphones to access the web-based gate pass management system. A responsive web system is a considerable approach to resolve screen size and input method challenge of the smartphone; however, the study shows many users are not interested to use a mobile browser for accessing web services. Hence necessitate the implementation of a mobile application for enhancing the existing web-based gate pass management system. Web-based gate pass management system requires printers for printing gate pass permission, and barcode scanners are required for scanning gate pass permission paper at the security gate. The cost of hardware and printing materials is waived through the utilization of mobile phones to create shareable digital gate passes, as well as utilizing a camera as a barcode scanner. The camera can be used for photographing gate pass users for extra records. Seventy (70) respondents were selected through the non-probability purposive sampling technique. The mobile application was developed, tested, and validated through hundred potential users.
