0marAmr / Fan-Control-System

[MCU]: AVR atmega32

Fan-Control_System_AVR

Implemented via AVR atmega32 MCU with 1 MHz internal clock frequency.

Project Description:

• The fan is automatically turned OFF or ON with variable speed according to the temperature.
• Based on the temperature read from the LM35 sensor, the MCU sets the fan speed as follows:
    i. If the temperature is less than 30C, the fan is turned off.
    ii. If the temperature is greater than or equal 30C, the fan is turned on with 25% of its maximum speed.
    iii. If the temperature is greater than or equal 60C, the fan is turned on with 50% of its maximum speed.
    iv. If the temperature is greater than or equal 90C, the fan is turned on with 75% of its maximum speed.
    v. If the temperature is greater than or equal 120C, the fan is turned on with 100% of its maximum speed.
  
• The fan status is continuously updated on an LCD screen.
