47 Development of Energy Saving Smart Home Prototype

In this work, we are interested in developing a prototype of smart home for energy saving. The prototype uses a microcontroller PIC18F458 with various sensors such as a temperature sensor, infrared sensor as well as actuators to control the lights, air conditions, as well as the fans appropriately etc. It detects the number of people in a room, adjusts a proper temperature for the air condition, turns on the fan if needed, turns on and off the light appropriately. The simple measurement shows that using the sample prototype can save the electricity cost for every test case
