Microcontroller Based Office Communication Model (MBOCM)

Technology has brought convenience to office activities by integrating communication model into electronics device. This work focused on Microcontroller based office communication model for establishing end to end communication nudes primarily to achieve fast message delivery without the visitor consent. An Atmel microcontroller (AT89C52) was used to design and construct the device and administrative languages were coded in numeric codes using C programming language which was compiled on keil micro-vision compiler platform. Communication model was setup using duplex communication and the interfaced keypad was used to input visitor’s request at lower officer front desk. The user (lower officer) will get quick response (Allow or Deny) from higher officer therefore, the lower officer will respond to visitor(s) using MBCOM message status. The results proved that the designed Microcontroller is efficient for running secured end to end communication broadcasted over LCD display. The performance is excellent in terms of timely response and also with respect to message delivery from both ends.
