A smart fan project based on the Liangshan School

Multiple Wind Speed ​​Adjustment: The smart fan features five wind speed settings, allowing users to choose the appropriate speed according to their preferences.


Temperature Sensing: The fan has a built-in temperature sensor that detects the ambient temperature. When the temperature rises, the fan automatically slows down to maintain a comfortable environment.


Wind Speed ​​Display: The fan is equipped with an LED display that shows the current wind speed in real time. This provides users with an intuitive understanding of the fan's performance.


Intelligent Control: The fan can be remotely controlled via a remote control or smartphone app, allowing users to easily adjust the wind speed and monitor the temperature.


Energy-Saving Mode: The fan also features an energy-saving mode that automatically optimizes the wind speed to reduce energy consumption, thereby lowering electricity costs.


Engineering Implementation Steps:


Design Phase: In this phase, the fan's appearance, control circuitry, temperature sensing system, and wind speed display are designed. The materials used and manufacturing processes are determined.


Manufacturing and Assembly: Manufacturing of components begins, including fan blades, motor, temperature sensor, control panel, etc. These components are then assembled into the final product.


Software Development: Embedded software is developed to control the fan's functions, including temperature sensing, wind speed adjustment, and LED display functionality.


Testing and Calibration: Conduct comprehensive testing of the fan to ensure the accuracy of the temperature sensing system, the stability of the fan speed adjustment, and the correctness of the LED display.


User Interface Development: Develop a smartphone app or remote control interface if needed, allowing users to remotely control the fan.


Production and Quality Control: Mass-produce the fan and conduct quality control to ensure each product meets standards.
