PERANCANGAN SISTEM PENGENDALI DAN PENJADWAL LAMPU RUANGAN BERDASARKAN DATABASE MELALUI KOMUNIKASI WIRELESS ZIGBEE

Abstract

Improper of using electrical energy, example, forget to turn off the light when not needed is one of the cause of electrical energy waste that have to be solved. The losses impact for user is enlarging costs as much energy used, in this case energy wasted more precisely. Due to this problem, needed a system that can control lamp depending on needs. The aim of this final project is designing and building controller and scheduler system for roomlights based on database using wireless communication. Zigbee (XBee-PRO) is used as wireless communicator between master as controller and scheduler center and slave as equipment that controlled located in room. Slave is using AVR ATmega8535 microcontroller as core operator. Optoisolator is implemented as lamp sensor. Based on result, XBee-PRO can communicate each other until 200 metres on line of sight mode, and 90 metres on indoor mode. Master station can command each slave successfully. If there is error command replied to master station, it will resend last data packet. Each slave is controlled based on scheduled from database while on automatic mode. If system is operated on manual mode, command that’s transmitted from master to slave depend on operator that operates it.
