Science and technology is a double-edged sword; while it brings convenience to people, it also threatens the environment of human. The pollution of the ecological environment has reached a point that cannot be ignored. Traditional methods and measures to protect or monitor the environment can no longer meet the increasing environmental pollution. Therefore, we should use the latest scientific and technological achievements to improve our environment. Through high-tech means to monitor the changes in the ecological environment pollution, we always remind people to protect environment. With continuous innovation of sensing, communication, and embedded technology, the monitoring system also needs to be updated accordingly, which has great research significance. With Internet of Things technology, this work has researched and designed a multipoint ecological environment monitoring system. It can realize intelligent monitoring for ecological environment, achieving the goal of integrating the measurement parameters of the ecological environment monitoring, the system modularization, the real-time data transmission, and the integration of monitoring services.
