Locus Imperium is intended to read room data attributes such as temperature, humidity, and loudness. Additionally, the device counts and estimates how many people are in the room at any given point. All this data will be displayed in an Android app that will also allow the user to set acceptable limits for the room air quality. If these limits are exceeded, the user will get an alert to improve the room environment.

The system will mainly consist of a device that is intended to be placed at the entrance of a room.

• By using ultrasonic rangers, it will count the people that enter and exit the room.
• To measure the loudness levels, we will make use of the in-built WIO Microphone.
• For measuring other conditions we will use a temperature & humidity sensor to measure its respective parameters.

All of this will be controlled by the mobile app connected to the device, and the information will be displayed in both systems.
