AIR QAULITY SENSING AND CONTROL SYSTEM FOR SCHOOL

A system for measuring and controlling air quality of school facilities is provided to transmit and store data for determining air quality of classrooms in real time through comparison between air qualities of classroom air and the atmospheric air, thereby carrying out ventilation or air conditioning based on the determination. A system for measuring and controlling air quality of school facilities includes indoor units(100) installed in individual classrooms and having a measuring part for sensing concentration of various components of room air, a signal processing part for converting the detected signals to digital data, and a communication part for transmitting the converted digital data. An outdoor unit(200) is mounted outside a building and having a measuring part, a signal processing part and a communication part similar with those of the indoor units. A CPU(300) receives the data transmitted from the indoor and outdoor units to store, and determines air quality of the indoor units. The CPU compares the air quality of the individual classrooms with the atmospheric air quality to determine whether to carry out ventilation or not. The CPU compares a mean value of the air quality data of all the classrooms with those of the individual classrooms to determine whether to carry out ventilation or not and whether to operate an air conditioner or not.
