Module in which the security acces employed card for entering the room Every card has it ID number . the system runs by using two security accesses whwre the first access is by sticking a card thourgh regiestered ID in the module (radiofrequency identification ) . Then , the regiestered ID will retract the handle of magnetic door lock while if not , it will sound the alaram for 10 second s adnd the handle of magnetic door lock will remain eleongated . The second access uses unlock button magnetic door lock will remain elongated . The second accses uses unlok button of magnetic door lock handle that will be retacred for 30 seconds after acces permted. The tool uses a magnet as identification if someone enteres the room illegally without having any access then for arduinoto give notification on LCD ( liquid cristal Display ) in 16 x 2 that someone ilegally opening the door . keyword : Room Security , RFID , Arduino , Automatic Key â } }
