Development of data monitoring application based on IoT

摘要

There is a sustained and changing voltage between living trees and soil, which may be related to transpiration. If the data of bioelectricity, transpiration characteristics and environmental factors can be observed continuously, thereby finding the relationship between the voltage and transpiration, a new method for transpiration measurement can be provided. In order to carry out long-term observations and obtain relevant data, and to explore the relationship between the voltage and transpiration further, a data monitoring application based on IoT was developed by using the Flutter mobile framework. The application can access the database, obtain data, and display real-time data and data charts, which provides a technical basis for the study of the relationship between the voltage and transpiration.
