Multichannel temperature scanner and controller

MULTICHANNEL TEMPERATURE SCANNER AND CONTROLLER

A project report submitted

In partial fulfillment of the

 

Diploma

In

Electronics & Communication

  • Ø A  simple introduction about the temperature controller circuit.

 

  • Ø This circuit project is mainly used used for    temperature indicator, temperature controller
  • Ø And in controlling device depend on temperature.

 

  • Ø Controlling devices like air heater,factory,industrial ,    application.

 

  • Ø In temperature controller circuit there are two part consist of
    • adc 0804 interface with at89s52.
    • lcd interface with at89s52.

 

  • Ø The hardware circuit of temperature controller with controller to need the programming.

 

  • Ø There are two possibilities fso programming
  • Ø assembly language programming
  • Ø c language

 

  • Ø Here we use the assembly language programming using keil(µVision4 IDE) software.

 

  • Ø This programming usually load in the at89s52 controller ic.

 

  • Ø At89s52 is a family of 8051.

 

  • Ø The programming for 8051 . this system is called embedded  system.

 

  • Ø The main principle of this project to indicate temperature, analog to digital, to control the temperature & interfacing.
