Control of Pharmacy Degree Heat

Some sensitive systems need a specific temperature to Maintaining the quality and effectiveness a pharmacy contents for example. Need pharmacy to store the pharmaceutical and medical appliances at a certain temperature, temperature inside the pharmacy must be controlled. So, I decided to construct a system that controls the cooling devices used in pharmacies. The system works by increasing the speed of the cooling device when the temperature increases inside the pharmacy. The system also decreases the speed of the cooling device when the temperature decreases inside the pharmacy. The proposed system gives acceptable result in the real test.
