Air conditioning system of an office sensitive to relative humidity and oxygen concentration

An experimental research was carried out to improve air quality by adjusting the relative humidity and oxygen concentration with the PIC microcontroller in present study. Taking account sub limit for oxygen concentration and relative humidity a ventilation system were arranged and tested to determine useability. PIC microcontroller programming software was operated to run ventilator fan to provide oxygene rate from fresh air for the environment and cold steam tool for moisture. People entering the office environment and in an office environment (the door is always closed except for the entry-exit process) reduces environmental oxygen concentration at certain periods during working hours with their breathing, and by activating the relay and running the ventilator, the PIC micro-controller provided fresh air intake indoors. During the lunch breaks or without working hours when people are outside, the absence of indoor breathing leads to the atmospheric oxygen levels again.
