Tiivistelmä
Building automation is used to improve occupant comfort by automating different controllable, measurable and regulatable systems. Well-designed automation makes it possible to build efficient, economical and easy to operate systems for air conditioning, temperature, moisture or CO2 concentration for instance.
The purpose of this thesis work was to design and build a prototype for an I/O card to monitor a heat recovery ventilation system in a building for a Finnish company Waido Oy. The I/O card was designed to measure temperature and pressure using sensors. Measurement data is sent from the sensors to a microprocessor that processes and sends the data further to a main processor. I2C is used to communicate between the two processors. An output from the microprocessor was also designed to the I/O card though it did not have a specific purpose in this project. This text focuses on electronics and circuit design, but does not address programming or software.
In the end a working prototype was made, but some details could have been polished a bit more. Due to time running out one output had to be cut from this circuit design, however it is simple and easy to implement it to the design later.
