ADVANTAGES1.Main advantage of this project is that it helps
in energy conservation. Because when there is nobody inside the room then lights are automatically turned off.
2. Human efforts to count the number of person is eliminated. Since this project does the automatic person counting with the help of two sensors installed on door frame.
3. Savings energy.
APPLICATIONDigital Visitor Counter can be used in various
rooms like seminar hall, conference hall where the capacity of room is limited and
should not be exceeded. Project will display actual number of persons inside the room.
FUTURE DEVELOPMENT1. Voice alarm system can be added to indicate
that room is full & persons can’t enter inside.2. We can increase the maximum number of
persons that can be counted by implementing the external switches and leds.
3. We can send this data to a remote location using mobile or internet.
