Synopsis "An electronically controlled automated security access gate"

The control of access to a property or building that uses a gate is better done using electronic devices. The electronically controlled automated security access gate achieves this by using an RF transmitter-receiver pair. A microcontroller is programmed to decode a given sequence of charaters that is entered on a keypad and command a transmitter module to send out this code as signal at a given radio frequency. Upon reception of this RF signal by the receiver module, another microcontroller activates a driver circuitry to operate the gate by opening or closing it automatically. The codes for the microcontrollers were written in C language and were debugged and compiled using the KEIL Microvision 4 integrated development environment. The resultant Hex files were programmed into the memory of the microcontrollers with the aid of a universal programmer. Software simulation was carried out using the Proteus Virtual System Modelling (VSM) version 7.7. A scaled-down prototype of the system was built and tested, and found working okey. The electronically controlled automated security access gate can be useful in providing security for homes and organizations.
