An Effective Combination of Microcontroller and PLC for Home Automation System

Abstract

In this paper, a smart home automation system is

proposed to control home appliances and to make a home safer

using electronic controller. Also, Grid-Eye sensors are used to

detect the presence of the occupant in the home upon which the

activation of any appliance depends. As a result, all the electric

instruments of the home run automatically when necessary,

and the residents do not need to turn on/off of any electric

appliances like air conditioner, fan, light, water heater or any

other home appliances. Also if a person wants to make on/off of

any utilities, he can easily make it by using android apps or by

using a wireless network which is interfaced with the system.

In addition to home automation, when any mishap happens in

the home, GSM sends SMS to warn people about the accident.

If a person wants to know the status of his home utility system,

when he or she out of the home, he can also use GSM

technology. Proteus simulation software is used to test the

effectiveness of the proposed designed system. To control large

electric machines like water pump, elevator and generator,

PLC module is used. In this case, we also consider different

conditions to run large electric machinery automatically. This

designed system provides more convenient and flexible control

for a smart home or a building. If implemented, the model will

be beneficial for the promotion and popularity of smart home

automation system.
