Automated Temperature Control System

Project Description:

1. AT89S52: The AT89S52 is a low power, high performance CMOS 8-bit microcontroller with 8k bytes of in-system programmable flash memory. This is a powerful microcontroller which provides high flexibility and cost effective solution to many embedded control applications. It has the following standard features: 8K bytes of flash, 256 bytes of RAM, 32 I/O lines, watchdog timer, 2 data pointers, 3 16-bit timers/counters, on-chip oscillator and clock circuitry.
2. Thermistor: It is a temperature sensing element, material which exhibits a large change in resistance proportional to a small change in temperature.Usually have negative temperature coefficients which means the resistance of the thermistor decreases as the temperature increase.
3. Relay: A relay is an electrically operated switch.It can handles the high power required to directly control an elecric motor or other loadas is called relay or contactor.

Project Implementation:

1. Interface thermistor,DC Brushless Cooling Fan with 8051 Microcontroller
2. Power the components and upload the code to Microcontroller

Software requirements:

1. Keil Uvision 3: Keil Software makes C compilers, macro assemblers, real-time kernels, debuggers, simulators, integrated environments and evaluation boards for the 8051, 251, ARM and XC16x/C16x/ST10 microcontroller families
2. Programming Language: Embedded C language
