Building A Whole Home Information Awareness

Overview

The whole home information awareness device is based on an Arduino which makes it function as a controller that monitors sensors in all areas of the house.

Explanation

In each room, there is a microcontroller at a high level. The microcontroller is instructed to open and close the ventilation in a specific way, when the temperature or humidity sensors reached a certain level. The device has the main purpose of keeping all room not to reach more than 1.5° and 5% relative humidity as differentiated from any other rooms. This will maintain all rooms to have the same temperature where there is no hot guest bedroom or cold living room in the house.

The return vents of each room will contain temperature and humidity sensors along with servo motors connected to the main damper controls for each vent, and an air flow and pressure sensor in the HVAC main line to keep the motor from getting burned out. The sensor data is gathered together by an Arduino while the processing of data, controlling the sensors, and creating graphs are done by the Linux box. The graph updates every 5mins showing the current sensors.
