“…Recent studies in spectrophotometry have demonstrated the progress toward developing a simple homemade spectrophotometer [40][41][42][43][44]. These sensor systems use a 3D printed or cardboard housing with a place to put a sample and pass light through a cuvette to measure the spectral readings.…”

Nutrient monitoring in Micro Indoor Smart Hydroponics (MISH) relies on measuring electrical conductivity or total dissolved solids to determine the amount of nutrients in a hydroponic solution. Neither method can distinguish concentrations of individual nutrients. This study presents the development and testing of a novel spectroscopic sensor system to monitor nitrogen changes in nutrient solutions for MISH systems. The design phase determined that using an inexpensive AS7265x Internet of Thing (IoT) sensor in a transflective spectroscopic application could effectively detect small fluctuations in nitrogen concentraation. Next, a novel transflective sensor apparatus was designed and constructed for use in a MISH system experiment, growing lettuce over 30 days. Two solution tanks of different sizes, 80 L and 40 L, were used in the deployment of the system. Samples from each tank were analyzed for nitrogen concentration in a laboratory, and multilinear regression was used to predict the nitrogen concentrations using the AS7265x 18 spectral channels recorded in the sensor system. Significant results were found for both tanks with an R2 of 0.904 and 0.911 for the 80 and 40 L tanks, respectively. However, while the use of all wavelengths produced an accurate model, none of the individual wavelengths were indicative on their own. These findings indicate that the novel system presented in this study successfully and accurately monitors changes in nitrogen concentrations for MISH systems, using low cost IoT sensors.

“…It allows characteristics and performance of teaching instruction and materials to demonstrate a learning subject. It promotes understanding and models for instructional instruments and prototypes [20]. Indeed, print materials in instructional teaching theory focus on increasing activity practice and learning retention for leading mastery of the lesson.…”

The study examines the contribution of instructional teaching theory in educational system as a basis for effective teaching devices in learning as to print materials, electronic media, technology devices, visualization and graphics, games, and interactive resources. The study employs descriptive quantitative research designs because it measures and quantifies the variables of the study on the contribution of instructional teaching theory in educational system. Likewise, convenience purposive sampling is utilized in the study. It is a non-probability sampling method in gathering the sample size of the study. The study comprised one hundred seventy five (175) respondents only. Results show to offer and plan step by step lesson, time saving, assessment materials, testing, and worksheets, to create and allow multiple friendly learning for students to listen in audiobooks, CDs, using headset to avoid disturbance from other classmates, show to help and develop deeper learning and understanding process of students, and show learning factor on the concept of instructional teaching that can turn complex things into play. Findings show that there is a significant correlation on the contribution of instructional teaching theory in educational system as a basis for effective devices in learning as observed by the respondents.
