Temperature Fan controller

The System is fully controlled by the microcontroller AT89S52. It is a popular 8 bit microcontroller. The circuit consists of four switches, in which two buttons are used to increment and decrement the temperature value and the next button is to edit the temperature values stored it in the memory and the other button is cancel button. All the above functions are monitored and controlled by the 8 bit microcontroller AT89S52. More: This Project is used to control the Fan speed according to the temperature and it also indicates the temperature. The system will get the temperature from the IC (DS1820) and it will control the speed according the values stored by the user.

The described system is an embedded application designed to control fan speed based on temperature readings. The central component is the AT89S52 microcontroller, which operates at 8 bits and is known for its reliability and versatility in various electronic projects. The microcontroller manages the logic of the entire system, processing input from user controls and sensor feedback.

The circuit includes four switches: two for adjusting temperature values (one for incrementing and one for decrementing), a third switch for editing stored temperature values, and a fourth switch designed as a cancel button. This user interface allows for intuitive interaction with the system, enabling users to set and modify temperature thresholds easily.

Temperature sensing is achieved through the DS1820 integrated circuit, which is a digital thermometer capable of providing precise temperature readings. The microcontroller interfaces with the DS1820 to retrieve real-time temperature data, which it uses to determine the appropriate fan speed. The fan speed is adjusted based on user-defined parameters, ensuring efficient operation and comfort.

In summary, the system functions by continuously monitoring temperature via the DS1820, processing this data in the AT89S52 microcontroller, and adjusting the fan's speed accordingly. The inclusion of user controls enhances the system's functionality, allowing for personalized temperature settings and operational adjustments. This design exemplifies the integration of microcontrollers in temperature control applications, showcasing their effectiveness in automating environmental systems.The System is fully controlled by the microcontroller AT89S52.
