Due to rapid development of economy in Taiwan, industrialization and urbanization have brought great pressure on the environment. In particular, industrial water pollution has immediate impact on residential areas because the small urban area increases the chances of pollution spreading. The conventional water quality sensing instruments, such as pH meter and conductivity measurement are reliable. However, frequent manual calibration and cleaning are usually required, thus the manpower demand for maintenance is heavy. Also, monitoring instruments for regulatory items related to enforcement, such as heavy metals and chemical oxygen demand have the disadvantages of large volume and high installation cost. Therefore, the conventional water sensing instruments are not suitable for application scenarios on mass installation and distribution. The project have completed the following tasks: 1. Optimize the feasilities of water quality sensors and evaluate the feasibility if sensoring new items of water quality. 2. Implementation the quality control of water quality sensor.3. Improve diversified water quality sensing technology and expand field application verification. 4. Promote the application and environmental management of local government sensing IoT joint projects. Base on R＆D optimization, data analysis and environmental application, the team works with the central and local governments to gradually expand the impact of the project. Through the disclosure of water quality data, which cound improve the quality of the environment and make people feel the change from technology.
