Sensors for Availability using Virtual Interface

As all of us observed at the doors of a Company Manager, a doctor or a head of the organization, we find a sign board displaying whether the person is IN or OUT. This sign board is used to mention the availability of the person sitting on his chair in his covered room. These boards are operated manually. These boards have various designs as per the interest of the person or manufacturer like sliding, hanging, rotating and etc. This mini project brings different approach on the same information. This concept replaces manual operating system by automatic sensor based system. Sensors are smart enough to sense the availability of the person sitting on his chair in his covered room.
