Intelligent temperature monitoring and control system using AVR microcontroller

Controlling temperature has been a prime objective in various applications including refrigerators, air conditioners, air coolers, heaters, industrial temperature conditioning and so on. Temperature controllers vary in their complexities and algorithms. Some of these use simple control techniques like simple on-off control while others use complex Proportional Integral Derivative (PID) or fuzzy logic algorithms. In this project I’m going to discuss about a simple control algorithm and utilize it intelligently unlike analogue controllers. Here are the features of our controller:

  1. Audio-visual setup for setting temperature limits.
  2. Fault detection and evasive action.
  3. Temperature monitoring and display.
  4. Audio-visual warning.
  5. System status.
  6. Settable time frame.
  7. Data retention with internal EEPROM memory.
