Design an Automatic Temperature Control System for Smart Electric Fan Using PIC

This paper presents an innovative prototype design of electric fan with smart characteristics. This electric fan uses a microcontroller to produce an automation function. It also has a unique double feature designs, such as using 2 fans, 2 Light Emitting Diodes (LED) and 2 sensors. This is to ensure the cooling process operates more efficiently and effectively, especially for a large space application and in hot weather due to global warming. By applying the circuit, it offers a better life for human. It is really practical for senior citizens to make their life simpler. The circuit is also suitable for disabled people who have difficulty to switch on the fan manually. Lastly, the circuit can be manipulated by diversifying its function as a detector, where it can produce an alarm signal when emergency case occurs such as the house or premise is on fire.
