CUADRA, MARITES MOJICA and DE LUNAS, JOCELYN MESINA. 'Design and Development of a PC-Based Temperature and Relative Humidity Control Unit of a Forced Convection-type Multi-purpose Crop Dryer." Bachelor of Science in Computer Engineering. Cavite State University, Indang, Cavite. April 2001. Adviser: Ms. Florence B. Marero.
The design project was evaluated at the Agricultural Machinery Building, College of Engineering, Cavite State University, Indang, Cavite.
The study aimed to design and developed an automatic control unit that will control the temperature and relative humidity within the crop dryer.
The hardware of the system consisted of the interface card, power supply, relay module, temperature and relative humidity control unit and the dryer itself.
Visual Basic 5.0 was the language used to develop the software of the system.
The software provided the user-monitor Interface.
Results showed that the temperature and relative humidity within the drying chamber were automatically controlled. The machine was automatically switched off once the computed drying time elapsed.
