Weather Based Smart Fan

Abstract

At present state we are wasting electricity somehow or the other. One of the examples, of this is a living room fan which runs at a constant speed until changed manually. To protect and safeguard one's future we need to save energy. This system is based on a mechanized fan actions/speed controller using Arduino which authorizes actions/speed of the fan based on sensed temperature. Using Arduino microcontroller, it establishes authority and fast processing of all the devices attached to them (sensors and LCD display in this case) to obtain data and allows faster display of data in real time. LCD makes the weather monitoring system so much more convenient and straightforward. Temperature obtained by the sensor and speed of the fan are exhibited on the LCD. Arduino microcontroller is the main hardware in the electrical system, which commands all of the tasks. DHT 11 sensor is a very fast and effective temperature and humidity sensor and it convert the data into transferable signal and forwards it to Arduino microcontroller, which is then displayed on LCD in real time. Transistor is used to control the speed. Further it can be used with other applications like air-conditioner, heater, cooler, incubators, etc.
