Syaifudin, Dimas Yuniawan (2007) RANCANG BANGUN SISTEM KEAMANAN PINTU GESER BERBASIS MIKROKONTROLER AT89S51. Undergraduate thesis, Department of Physics, Diponegoro University.



A rolling door security system based on AT89S51 microcontroller has been designed and realized. This instrument can be used for building security system by a company or a luxurious house security. The hardware consist of 3x4 matrix keypad, uses 2 AT89S51 microcontroller, Limit switch, Relay driver circuit, Liquid crystal display circuit, Alarm circuit and DC motor. 3x4 matrix keypad used for entering password input which will be enter and give the data input to the 1st microcontroller. Then the output from 1st microcontroller will be sent to 2nd microcontroller which used for all processing data of the system. A data will be displayed using Liquid crystal display. In this system also available a buzzer that used for alarm. An alarm will be activated if a rolling door opened by force without entering password first. Also using DC motor that used for open a rolling door. This system was realized and can move a rolling door with entering password first. The code of password can be seen in the Liquid crystal display. Due to a rolling door security system based on AT89S51 microcontroller, security system can be more effective and efficient. The result of this final project is supposed to be widely implemented.
