Smart Fan

This project is known as a smart fan, it use the PIRsensor to detect motion and LM35DZ to detect heat and finally operate the fan. So, this project have the relationship with the temperature that act as a variable. Room temperature is a common term that can either denote a certain temperature to which humans are accustomed or a specific temperature and passive infra-red sensor is a pyroelectric devices motion by measuring changes in the infrared levels emitted by surrounding objects. This motion can detect by checking for a high signal on a single input output pin. Usually used as a security device in a monitored area to detect appearance of human. Our project have an objective to achieve that is to design automatic fan operating system based on indoor air temperature and human detection sensor. Then the next objective is to design a profitable project for the comfortable condition in home. This objective must be achieve to get a complete project. To support our project, we use UV Exposure Machine, The Etching Machine, Drilling Process Machine, and Printed Negative Plastic. This equipment has been used for process in Printed Circuit Board (PCB). There are many software to design the Printed Circuit Board (PCB) for example OrCAD, TINA software, PROTEUS and PCB designer. The layout is drawn by using PROTEUS software. The artwork that is designed in PROTEUS then is transferred to the negative film. It is printed using a laser printer. Then, the negative plastic film is exposed in the UV Exposure. This is where the PCB design is transferred to the PCB Board. The board is then go through the etching process. Next the board will go through a drying and drilling process. The board is drilled to make appropriate holes for the leg of components. A high speed drill press is essential for carbide drills. The last step of making PCB layout is the soldering. The leg of component then is placed at the hole that is drill before and soldering it by tin. Next equipment is a solder, adapter, multimeter, and Breadboard. For test the hardware circuit at breadboard, we use adapter and multimeter. Adapter is used for give voltage supply in a direct current (DC) and multimeter for troubleshoot this circuit before and after voltage supply are supplied. Solder is an equipment for soldering the components at Printed Circuit Board (PCB).
