Intelligent Energy Saving System
ABSTRACT
This project is proposing the household energy management and warning system for energy saving solution. The overall control scheme is mainly governed by a PIC16F877A microcontroller. There are four subsystems to be concerned (i) air-condition’s inverter control, (ii) lamp brightness control, (iii) power switching control (for general loads such as television, radio, fan, etc.), (iv) house hold electricity usage warning system. This whole system can monitor the power usage and display through a LCD monitor. Then, it can warn the users through LED bulbs when the power usage is getting close to the monthly prescribed energy usage levels. An experiment conducted by installing this system in an apartment room has shown a satisfactory result in reducing power usage level.
