PROTOTYPE PENGAMAN KOMPLEK PERUMAHAN MENGGUNAKAN RFID DAN SENSOR ULTRASONIK BERBASIS SMARTPHONE ANDROID
The housing complex is a residential area that is very crowded by residents where this place is usually used to interact with fellow residents of the complex to establish social relations between each other so that residents of the housing complex will know each other. To maintain the security of the housing complex, a complex security device is needed using RFID equipment and ultrasonic sensors that can ensure the safety and comfort of residents in the housing complex. The design of this tool uses RFID, ultrasonic sensors, wifi8266, andorid Smartphones and LCDs. In designing this housing complex security prototype where the RFID rider functions to read RFID tags that are only owned by residents of the complex so that when the RFID tag is attached to the RFID Rider the portal door will open automatically but if the RFID tag is not registered then the portal door will not open, then when the RFID tag is not registered, the portal door will not open. there is someone who will enter the house the ultrasonic sensor will activate the esp 8266 module which serves to give a message to the homeowner via an android smartphone, so that the homeowner knows that the house has been entered by an unknown person. And the owner of the house will contact the security guard in front of the portal door.
