What is it about?
This project studies temperature control using a microprocessor with an interfacing circuit. This type of control is studied theoretically and a circuit is designed and implemented by using a software program for a hospital building in Kirkuk city by choosing nearly 10 rooms. The program is written with the reference temperature using an Lm35 sensor that is suitable for this work, where it operates over a T range from 55 to 150, by entering machine code to the Microprocessor 8085 to collect data from sensors in the form of analog values, changes it to digital vales by Analog to Digital Converter, and enters it into the microprocessor. The Microprocessor 8085 takes data from sensors that has been changed to a digital signal by Analog to Digital Converter to receive to fuzzy logic controller, which is the best way in which this type of precision control can be accomplished by controller. Here we try to control the temperature of the system using the fuzzy logic controller from the data coming from the Microprocessor 8085. The Microprocessor 8085 has been selected because the error rate is very low and the results are very accurate.

Why is it important?
Temperature is a convenient term for the average transitional kinetic energy of the molecules of the body under consideration; some prefer to state it as the energy per mole associated with the translator motion of its molecules. While the temperature of a body, it's the thermal state that is considered with reference to its ability to communicate heat to other bodies [1]. Our fundamental concept of temperature is obtained from the sensation of warmth or cold, which we experience when we touch an object. Expressions such as "ice cold", "cool", "tepid", lukewarm", "red hot", etc. indicate that our qualitative appreciation of temperature precedes our use of numbers to characterize it [2].
Perspectives
The implementation of temperature control for hospitals using MP 8085 has been completed successfully. The communication within the control system occurs without any interference between different modules in the design. The design meets all the specifications and requirements. A program has been written in which the reference temperature can be chosen by the user, and the circuit will adjust the reference temperature according to the required specification by the process under the consideration temperature. It is difficult to control the temperature in a hospital, and fuzzy control is one of the best ways to control intermittent room temperature. The fuzzy logic controller has two inputs and one output. Temperature changes in the rooms can be controlled accurately to user specification due to the input of rules and temperature changes that have been given to the fuzzy control MATLAB circuit.
