The combination of mobile application and machine learning with environmental sensing and image processing device in monitoring the health and growth of the plant in real-time. The goal of the study is to develop a controlled environment for spinach by monitoring its health condition using image processing and supervised machine learning. The device collects real-time data for humidity, temperature, and soil conditions using different sensors. Diagnosis of spinach health status is done by capturing the images of spinach using image processing techniques. Two classifiers were used in detecting spinach health conditions, Green for healthy spinach or no damages on leaves and Green, Yellow, Brown for unhealthy or with holes, damages; this classifier is also called datasets. Spinach health status is monitored using a mobile application called Spinach Monitoring Application (SPIMON) and all collected data are stored in the cloud. The result spinach health status showed that its best to culture spinach in a controlled environment.
The study aimed to provide a microwave communication link design connecting Philippine Long Distance Company (PLDT) and Light Industry and Science Park I (LISP I) through Imoc Relay Station, PLDT’s main repeater station located in Calauan, Laguna. The link would serve as PLDT’s secondary connection or back-up in case of failure in their existing fiber optic link. To comply with the reliability requirement of at least 99.9998%, the study used qualitative method in determining necessary factors that could affect the design. These consist of the path profile, link budget, and azimuth. The calculations were accomplished based on the gathered data and suggestions given by the experts. The selection of radio equipment was based not only on the system requirements but also as recommended by PLDT. It was proven that the link design was feasible for PLDT’s data and voice transmission. It was also proven that using Siemens Digital Radio equipment best fits the requirements needed by the client-company as it satisfies both reliability and economic analysis. The study, therefore, recommended this microwave communications link design to Philippine Long Distance Company as it was proven reliable after obtaining an overall system reliability of 99.9999%
