GALLARDO, ARMANDO G., LAMSEN, NINO WHAY S., and ROCHELLE B. ROMEROSO. Design of a Microprocessor - Based Fertigation Process Using Mist Emitter with Shading System. Undergraduate Design Project. Bachelor of Science in Computer Engineering. Cavite State University, Indang, Cavite. April 2003. Adviser: Ms. Florence B. Marero. The study aimed to design an MPU — based fertigation process using mist emitter driven by the motor pump and by the solenoid attached to each unit of the design. On the other hand, the machine was also composed of the shading system driven by motors for shading different types of crops that are sensitive to radiation from the depending on the temperature gathered by the sensor within the greenhouse. The hardware part of the machine was divided into two parts: the microprocessor unit as the control unit of the system; and the mechanical part of the machine. The microprocessor unit served as the center of all commands that the other unit has to perform. Since the controller has programmed according to the user, it tells when to open each valve and the shading depends on the temperature setting and the reading by the sensor. Each and every time that the inputted data were satisfied, the machine automatically performed the task of watering, fertigating, and shading the plants. The language used in creating the software was Assembly Language. It was loaded on the EPROM of the controller that served as the special programmable read only memory that can be erased and reprogrammed repeatedly. The operation was done by inputting the corresponding data, which include the starting time, ending time interval, cycle time, duration, open temperature, close temperature wherein the machine performed its operation when inputted data were satisfied.
