This Project is used to control the temperature of boilersand it also indicates the temperature. The system will get the temperature from the IC (LM35) and it will control the speed according the values stored by the user.
The System is fully controlled by the microcontroller AT89C52. It is a popular 8 bit microcontroller. The circuit consists of heater and a cooler and to edit the temperature values stored it in the memory
All the above functions are monitored and controlled by the 8 bit microcontroller AT89C52.
2.LM 35 (Temperature Sensor).
