Abstract
Now day there are various requirements of common-man. Internet of Things is going to play essential role in application such as smart home, industrial internet, healthcare and security systems, smart cities, etc. In this work, we are implementing smart digital fan module for controlling fan speed based on room temperature, and also turn on or turn off based on presence or absence of man body. And also we can access the temperature remotely through cloud. Temperature of the room can be sensed by using DHT11 temperature sensor. The sensed signal is send to microcontroller. If temperature is low then fan rotates slowly and if the temperature is high then the speed of the fan will be high. ESP8266 Wi-Fi is interfaced with microcontroller to show the current status of the project with help of mobile phone. The developed approach is benefited regarding preventing the waste of energy when it is not hot enough to use a fan and assist the disabled to switch on or off fan automatically.
