Bangladesh is currently facing 1500 MW of power shortage causing serious dislocation in all spheres of life including production in fields and factories as well as in the section of cellular communication. As a result of giving support to the increasing customers the operators are improving their network by building new BTS all over the country which requires a great deal of electricity support. So to save the electricity and make the use of air conditioner less a system called Intelligent Ventilation System (IVS) is developed. An IVS is an electronic instrument that records data from the environment condition and take decision how the room temperature should be controlled. This research work deals with the design and construction of a ventilation system using the PIC16F877A which includes 10 bit Analog to Digital Converter (ADC) for data conditioning and a 256 byte EEPROM for data storing. Here we use a 4X20 line Liquid Cristal Display (LCD) for display section as well. General Terms ADC, Air Conditioner, BTS, Fan, LCD, Microcontroller.
