Abstract

In Vietnam, the environmental pollution situation is very complicated; the quality of the environment has declined sharply in many places. The data and observations collected in environmental monitoring programs are valuable and required for many projects to provide information to regulatory agencies. Therefore, having a tool to support collecting and sharing environmental data is essential. Moreover, along with the development of science and technology, Citizen Science is emerging as a new direction for building community-sourcing data sources. It makes data collection convenient, inexpensive and relatively fast. This paper presents software development on mobile devices with functions to collect and share environmental monitoring data. In particular, the study focuses mainly on two types of data: air quality and water quality. A cross-platform Android and iOS application built on Flutter with key functions such as allowing users to create environmental pollution reports, display contaminated area information, and send pollution warning information. , etc. The software product of the research partly helps to detect, receive and warn of environmental-related problems more quickly, accurately and conveniently.
