An IOT Appliance for Controlling the Fan Speed and Accessing the Temperature through Cloud Technology using DHT11 Sensor

Abstract

In day to day, there are various necessities of common man. Internet of Things is going to play a vital role in applications such as smart home, smart cities, Industrial internet, healthcare systems etc. In this paper, we are presenting the module developed for controlling fan speed based on room temperature and also accessing temperature remotely through cloud. Temperature of the room can be sensed by using DHT11 temperature sensor. If the temperature is low then fan rotates slowly and vice-versa. Temperature of a particular room can be found from anywhere using DHT11 sensor and hosting on cloud. The proposed approach is accurate in terms of processing time, less circuit size, no external clock required and programming an arduino is easy when compared to 8051 micro processor. The developed approach is benefited in terms of 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. Experimental evaluation shows that the proposed approach is accurate and also takes less time.
