Tiivistelmä
The goal of the project was to implement a system that would control a ventilation system in order to equalize the pressure between the inside and outside of the building.
The system consists of one or several units that measure the difference in pressure between the inside and outside of the building, and a unit that uses the data obtained from those sensors to adjust the output of the ventilation system.
Each unit is based on a LPCXpresso microcontroller and uses an XBee module for wireless communication. Sensor units use a differential pressure sensor to detect the pressure difference, and send the data to the ventilation control unit. The ventilation control unit reads control signals of a ventilation system, makes adjustments to them based on the pressure difference, and sends the adjusted pressure signals to the intake and exhaust fans of the ventilation system.
The system was successfully implemented and the testing confirmed its effectiveness in achieving its purpose.
