FAN CONTROL USING ARDUINO MEGA 2560

Abstract

There are some tools that can be used to influence the air temperature to be more comfortable, such as: fan, air conditioner, etc. In the industrial case, fan is preferred to be used as a tool to improve the working comfort in the worker’s area because the price of a fan is cheaper than the price of an air conditioner.During the internship conducted by the author in an automotive company,many of the fans are broken for so many times due to extensive use without rest. From these points of view, the idea to design and to implement a “Fan Control Using Arduino Mega 2560” came up. This final project emphasizes in designing the hardware and the software that will work as an integrated system in the form of a circuit that will control the fan. Through the controller, the auto on-off fan can be realized based on human presence. An infrared sensor is used to control the state of the fan. The fan will be on if there is human presence.The other task of the control system is to control the rotation speed of the fan based on the air temperature. The testresults of the whole functions show that thefan control using Arduino Mega 2560circuit can operate well and fulfil the preset objectives.
