The platform, using dual element pyroelectric infrared sensors (PIR) sensors, rotates itself independently to direct air flow to whatever position a person moves to. In addition, the fan includes another setting that allows precise rotation between two people. These modes are selectable by the user. The running mode is displayed on an LCD. We decided to pursue this project because we had become fed up with the common fan's limitations. The platform is working in two modes: single mode and multimode. In single mode, when the right sensor detects human presence, it signals to the microcontroller (18F452) to rotate the motor counterclockwise. Similarly, when the left sensor senses human presence, the motor will rotate clockwise through the microcontroller. In multimode, the platform will rotate between two or more persons with precision. Another feature of this platform is that when you don't want to rotate it, you don't have to select any mode.enThesis
