Abstract
The design and construction of the
solar-powered intelligent greenhouse controller that intended to serve as a
solution for sustainable farming are elaborated. The system was developed to
automatically monitor and control critical environmental parameters like
temperature, humidity and soil moisture which are necessary to foster healthy
growth of water leaf (Talinum triangulare). The system integrated Arduino Uno
microcontroller, DHT11 temperature and humidity sensor, soil moisture sensor,
relay module, fan for cooling, water pump, LCD display and solar-power energy
supply. Data were taken and continuously monitored with automatically
controlled actuators actuated whenever any of the environmental parameters
deviated from set reference. The system was tested over five days for
efficiency and accuracy. The results showed that, the greenhouse was able to
provide ideal environment for plant growth through control of irrigation and
ventilation system. When the temperature was more than 29oC, cooling
fan was activated to lower the temperature, and water pump was actuated when
the soil moisture value was less than 45%. The displayed temperature and
humidity values read on LCD were also consistent with measured readings. The
designed system was proven to significantly reduce manual intervention, improve
utilization of resources and foster sustainable agricultural practices. Its
usage on solar energy enhances the usability in remote and off-grid
communities. Hence, it is a feasible, effective and environmentally friendly
approach to modern agriculture.
