Abstract:
This research proposes a household energy management and warning system for energy
saving solution. The overall control scheme is mainly governed by a dsPIC33
microcontroller. There are four subsystems to be concerned (i) air-condition's inverter
control, (ii) fluorescence brightness control, (iii) power switching control (for general
loads such as television, radio, fan, etc.) and (iv) household electricity usage warning
system. The energy usage can be displayed through an LCD display. In addition, users
are warned by the status of an LED bulb when the energy usage is getting close to the
prescribed levels. The experimental works have been conducted by installing this
system in an apartment room. According to the experimental results, the satisfactory
results in reducing energy usage can be observed.
