The project of the position locator can be used in different infrastructures where we can get the information about a person where is he/she currently is and their current location. The project being described here shows the applicability of a position locator in the college premises. The aim of the project is to identify the location of a teacher/student who carries an RFID (Radio frequency controlled identification transmitter). The receiver used here is an again an Rf receiver which can be kept in multiple areas and spreading all around the premises of the college like library, ground, canteen, building, reception etc. Thus when you have to identify the presence of a particular teacher, just enter his/her password (transmitter code) and check his presence on computer.
The software support the hardware interfaced with it and also gives time/date etc. on display screen. So we can get the clear location of the teacher where they presently are that is under which receiver’s range are they available adjudging the actual location of the teacher. The project uses a relay driver card interface with the PC through the parallel port of the PC to establish connectivity to provide the display. Thus this interface provides the essential display of the positions of the teachers where they are present.

OBJECTIVES
1) To construct an RF transmitter with its aligned RF receiver (1 to 5 nos. optional).
2) To design a relay driver card interfaced with RF receiver duly connected to pc parallel port.
3) To write a program in ‘C’ to display the different positions of students/teacher in the college premises with time.
