  This study focused on the development of a smart greenhouse system for
hydroponic gardens with the adaptation of the Internet of Things and monitored
through mobile as one of the solutions towards the negative effects of the
worlds booming population, never ending - shrinking of arable lands, and the
effect of climate change drastically in our environments. To achieve the goal
of the study, the researchers created an actual hydroponic greenhouse system
with completely developing plants, and automation in examining and monitoring
the water pH level, light, water, and greenhouse temperature, as well as
humidity which is linked to ThingSpeak. The developed SMART Greenhouse
monitoring system was tested and evaluated to confirm its reliability,
functions, and usability under ISO 9126 evaluation criteria. The respondents
who include casual plant owners and experts in hydroponic gardening able to
test and evaluate the prototype, and the mobile application to monitor the
parameters with the results of 7.77 for pH level, 83 for light, 27.94 deg C for
water temperature, 27 deg C for greenhouse temperature, and 75% for humidity
with a descriptive result in both software and hardware as Very Good with a
mean average of 4.06 which means that the developed technology is useful and
recommended. The SMART Greenhouse System for Hydroponic Garden is used as an
alternative tool, solution, and innovation technique towards food shortages due
to climate change, land shortages, and low farming environments. The proponents
highly suggest the use of solar energy for the pump power, prototype wiring
should be improved, the usage of a high-end model of Arduino to address more
sensors and devices for a larger arsenal of data collected, enclosures of the
device to ensure safety, and mobile application updates such as bug fixes and
have an e-manual of the whole systems.
