IOT-based soil moisture monitoring system using android mobile

Thesis Bachelor of Science in Computer Engineering University of Rizal System-Morong 2019

EXECUTIVE SUMMARY: The primary objective of this study is to improve the current soil moisture monitoring in a farm through an IoT-based soil moisture monitoring system using an android application. Preliminary testing was done at the sustainable agriculture and natural resources institute, an integrated unit of the University of Rizal System, Tanay Campus that serves as an integral part in research and development. The setup was done on a farming plot that was newly prepared for seeding. The system was able to send raw soil moisture data from the plot to the databased with a fixed interval of 1 minute from the last time a data point was sent. The devices ran on a single lithium-ion battery being charged by a five-volt solar panel eliminating the need to be connected on a power grid. The data that were sent to the cloud database quickly became available to the android mobile application client. This mobile applications presented the stored data in a simple and organized way that made sense to the end-user. The researchers used questionnaire checklist to evaluate the level of acceptability of the system in terms of accuracy, functionality, maintainability, performance efficiency and user-friendliness. There are thirty (30) respondents for the study, the experts, end-users and computer engineering students. The research was conducted through descriptive developmental method. The researchers used developmental method in the study to come up with the system and a descriptive method for using a questionnaire checklist in gathering information and analyzing were done to further validate the data gathered. The IoT-based soil moisture monitoring system using android mobile application was successfully developed by the researchers. The system has a total investment cost of Php. 5,000.00 and the system was able to monitor the uniform exact amount of soil moisture content that the traditional soil moisture gathering technique. In conclusion, the system is able to monitor the moisture of the soil. The design and programming of IoT-based soil moisture monitoring system using android mobile application is feasible because the material needed are locally available and programming the system is an open-source system. The IoT-based soil moisture monitoring system using android mobile application is economical in terms of manpower, location availability, and resource allocation. In recommendation for future researchers, the system can be used as means of reference to make an automated water irrigation. The system may be tried in an open field to determine whether it can satisfactorily function just like in a green house or protected cultivation system and crops monitoring system may also be incorporated as part of the future study.
