The project study, Development of Microcontroller-Based Aeroponic System, was
designed to monitor, detect, and provide efficiency for modern technology when it comes
to farming. The automation of the features of the project is done coded in the
microcontroller NodeMCU. The prototype is programmed to switch on or off the
attached devices every time it goes beyond the set limit or value. There are smart sensors
for proper detection of temperature, humidity, light intensity, and water level. There are
air coolers and Peltier cooling systems to maintain the desired temperature. The LED
light that provides light frequency needed by the plants to stimulate photosynthesis. The
misting process is intended to achieve the desired humidity and provide proper aeration
for plants. There is a relay that acts as a switch to properly turn "ON" or "OFF" the
specific device. The LCD I2C driver provides the actual display of the parameters inside
the prototype. The CCTV camera is used to monitor and see the plants even when the
user is away. The Blynk Application shows real-time readings of the parameters when
online or connected. The project was created using local-quality materials to ensure its
durability. It was tested and validated in terms of its hardware components, program
execution, and Blynk application interface and responses. All of the tests were performed
and met the expected outcomes. Thus, all the evaluation results passed. It was evaluated
by 25 respondents, composed of five Experts, five Agriculturists, and fifteen Farmers in
Sariaya, Quezon Province. and was assessed using Likert’s scale and descriptive
interpretation, which used the TUP evaluation instrument to get the mean for
functionality, aesthetics, workability, durability, economy, and safety. The grand mean
obtained was 4.51 out of 5, which is described as "Highly Acceptable". The study
concluded based on its findings and results that (1) the prototype can grow strawberries
aeroponically; (2) the project is highly functional and recommended for small-scale
businesses not only to farmers but also to simple people like us; (3) the use of local and
cheap yet high-quality materials maintains the project's quality and efficiency; and (4) the
advice and recommendations of panels and technical experts contributed to the project's
feasibility.
