TORRES, RAYMOND JAMES P. and REALES VINCENTSON M. Development of a Microcontroller-Based Ventilation System. Undergraduate Designed Project, Bachelor of industrial Technology, major in Electrical Technology. Cavite State University, Indang Cavite. May 2017. Adviser: Prof. Danielito R. Escano.
Microcontroller-based ventilation system role is for the users to be more comfortable. Though the aid of microcontroller we can operate the system from a certain distance. The remote control transmits a tone using a radio frequency. This tone is decoded by a receiver, since the receiver only switches when the tone is receive and the system will function according to its program.
The existing Room 205 of the Department of Industrial Engineering and Technology (DIET) has no existing ventilation system. The users of the room are having discomfort because of the ambient condition of the room so we design a microcontroller-based ventilation system to improve the Room 205.
This project aimed to develop a microcontroller-based ventilation system in one of the room in the Department of Industrial Engineering and Technology (DIET).The development will include the operation of a multiple electric fans simultaneously and separately with same microcontroller device. This will make the system more convenient to use by removing the problem of having multiple remote controllers. The design project was developed from January 2017 to March 2017 in Brgy. Alulod, Indang, Cavite. The project was evaluated by the student and instructor in Electrical Technology Section of the Department of Industrial Engineering and Technology under the College of Engineering and Information Technology.
The design project was limited on the improvement of room 205 in the Department of Industrial Engineering and Technology. The ventilation system will be microcontroller-based for the different applications such as it can be operated a simultaneously and separately by a single microcontroller. The room will be ventilated using four orbit fans which can only be manipulated by the designed microcontroller remote switch. This will be programmed using Arduino IDE software for programming.
The materials that used in this project were checked and research using internet Also we have canvassed in personal, to make sure that the materials are in good conditions to determine the functionality, workability, and the efficiency of the materials. The researchers do search for all the needed materials to ensure its availability for the design project and other contacts in public will be considered in giving information for all needed materials in this project design. We have purchased all needed materials in this project design directly in E-gizmo Electronics shop in Manila and in Circuit Rocks shop in Paranaque. We also bought some electrical materials in nearest hardware supplier. We considered other information that we can help in purchasing. In terms of price our priority is the quality and durability of the materials of the design project.
The frame that we have fabricated is made out of a fiber glass. First we measure the fiber glass and mark a line for the guide where we will cut it. We have cut the fiber glass using a slicer and scratch it back and forth until it has a deep mark, then we pushed it carefully so it will cut into two. After we cut all the fiber glass according in to its measurements, we assembled it using super glue. The frame has a hole for screw for easily covering or removing of the housing cover.
This project design composed of Gizduino Microcontroller, RF module 4 relays, single relay switch, Terminals and 4 single switches. These components are mounted in the fiber glass base using screws and knots for easy assemble and disassemble in case of replacing some device .These components are covered by a fiber glass frame and cover, so you can see all the components inside the housing. It has a good wirings and tagging's so it is easy to determine where the wires were connected. The remote control holder is placed beside the door of the room, it has a magnetic strip. The remote control device also has a magnetic strip at the back so it can easily place at the remote control holder. The main function of this project design is to control the power of the orbit fan easily using a remote controller. The microcontroller-based ventilation system can operate and control the power of the orbit fans but cannot control the speed of each fans, however it can still change the speed in the conventional switches. In case of malfunction of the system the orbit fan can be used through manual operation if the single switches were turned on. The added feature of the design project is the automatically power down of appliance. If the user forgot to turn off the orbit fans, the system will automatically shut down after two hours to prevent power consumptions. However if the system shut down it can be easily reset. The reset button is placed beside the lighting switch.
