Introduction
Purpose
The purpose of this software is to control the temperature of industry equipments, rooms, boilers, electric generators, steam turbines, combustion engines, etc. This project is specifically designed to maintain the temperature of the room by controlling Electric Fan and Electric Bulb or Heater.
Working
This software will continuously monitor the temperature of room (Ambient Temperature). If the ambient temperature increases above the desired temperature level, then the software will switch on the Electric Fan. On the other hand, if the ambient temperature decreases below the desired level then the software will switch on the Electric Heater or Bulbs and switch off Electric Fan. If the ambient temperature is equal to the desired temperature level, then the software will switch off both Electric Fan and Heater.
Project Analysis
This project is divided into two parts:
- The Hardware side
- The Software side
The Hardware Side
First of all, I have designed the hardware. The components that I have used and the circuit diagram is shown below:
The Software Side
The software is created in Turbo Basic. The software reads the data from the Standard Parallel port shown above from pin No. 2 to 9. It processes the input data and then compares it with the user desired temperature entered by the user.
The picture shown above all is the first animated window that appears when the user runs the software. Then the software directs the user to enter the temperature he/she wants to maintain. Afterwards, the software starts monitoring the temperature. The window that appears next is shown below:
This window remains there until you press the Esc key. With the help of this software, you can enter the desired temperature that falls in the range from 0 to 105°C.
