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.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786200310439\"\u003e\u003ch3\u003eDesign and Implementation of An electronically controlled automated security access gate\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786200310439","offer_id":39447020961885,"sku":"9786200310439","price":61.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ed757ab8-616a-418e-971e-6717153d5039.jpg?v=1770363214","url":"https:\/\/shop.autorenwelt.de\/products\/an-electronically-controlled-automated-security-access-gate-design-and-implementation-of-an-electronically-controlled-automated-security-access-gate-von-michael-ngumom-tyowuah","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
