Internet of Things (IoT) for measuring and monitoring sensors data of water surface platform

Nowadays, environmental monitoring is such an interesting system and plays such an important role in human life. Due to some challenges while accessing the data from a certain place, this paper presents a platform that monitors the environment at the rivers or lakes using the Internet. The system is focusing on doing a precision measurement in taking data to monitor the air and water quality as well as level of water for flood warning. This project using ARM microcontroller (LPC 1768) with several sensors attached to the platform; temperature and humidity sensor, carbon monoxide sensor (MQ-7), Global Positioning System (GPS) sensor, pH sensor, and water level sensor that act as an input. All the sensors data are saved into a data logger and sent to the Internet clouds. The data were collected three times per day using a time-based sampling method to get accurate data. Besides that, the data also can be monitored in real-time through the Internet cloud by the users either on their mobile phone or personal. The platform operates on the water surface area for long periods of time in diverse sensing environment. The long-term goal of this research is to ensure the users can monitor the changes happen at the site without needed to be at the site themselves.
