In this work we propose to apply the smart home technology in building a monitoring system which control classroom equipment. The system saves energy and lowering the maintenance cost by undertaking necessary actions according to classroom situations. When classrooms empty, system can be used to turn off related equipment remotely and wirelessly via XBee-based wireless network. The system can be used to control LCD proj ectors and lights in classroom. The system thus prolong classroom equipment lifetime and decreases the energy bills.Globally speaking, lower power consumption will also reduce global warming effect.
