Iot based platform for smart electric fans

Abstract

Existing speed control systems on conventional electric fans operate in only three speed modes: Low, Medium and High. Changing the speed of the fan is a manual action which may be problematic for many users, such as senior citizens ordisabled users or any user with mobility problems. Using Internet of Things (IoT) technology solves this problem by allowing variation in fan speed from very low speed to the maximum speed as a linearly increasing speed function. This paper clearly explains the functioning of the IoT, and how to use IoT applications for automatic fan speed adjustments in this way, resulting in the SmartFan. A smart mobile phone with a mobile app is used as the remote controller. A control algorithm was developed to control the interactive communications between the smartphone and the electric fan. This control approach has proven to be a useful and convenient method for the remote control of electric fan speeds.
