Remote access to smart energy conversation and

voice recognition feature for Visually Challenged

Abstract:

Energy is a very important aspect for any household, industries, agriculture and so. Managing

the energy efficiently and conserving it intelligently for appliances is very much important.

When it comes to energy saving, energy management is the process of monitoring,

controlling, and conserving energy in a building. Most homeowners aren't even aware of the

term, and take more of a haphazard, flying-blind approach to reducing their energy

consumption. Towards this, there has been lot of research work carried out for conserving

the energy. In none of the research, researchers have worked towards automating the

appliance control towards conserving the energy. Most of them concentrate on controlling

the appliances using android devices. Using the power of home automation, these state-

ofthe-art energy management solutions enable you to create a present schedule for the

operation of your home’s systems. You can also use your mobile device to manually operate

the systems even when you’re not at home. So, with the upcoming of machine to machine

communication where devices can be connected wirelessly leading to IoT, we have developed

an IoT based Smart Energy Management system where appliances like Fan and Bulb to start

with are controlled wirelessly based on humidity and light intensity information. These inputs

are used towards controlling the appliances intelligently rather than just switching on or off.

In addition, the system also keeps computing throughput the day power consumption of the

appliances which gives the user knowledge on power being consumed over a period of time.

These details are updated in Cloud server. This prototype system developed have achieved

energy conservation at every household.

We have built an android application “SMART HOME” and a central Tab

Application for user convenience. The user interface is made simple and the

application holds the calculated value that is stored in the database where the

operation occurs. Some of our application’s sample screenshots are shown below.

Working:

The project begins with the application registration, where the user updates the details of his

home with his email id and the password. Then the user logins to his smart home app and

updates the details. The user connects to every device that he wants to control using a relay

module, that relay module reports to the programmed Arduino and the Node MCU. The

connectivity then goes on to the next stage of connecting the application and the unit readings

for every device is denoted in the smart home application. The application lets the user to

Turn on or Turn Off the device either manually or by setting a unit limit which the device

automatically Turns Off.

The Meter reading is taken by the LDR sensor as the LDR sensor gives an interrupt each time

the meter LED flashes to the programmed Arduino, The Arduino takes this reading and

displays the it on an LCD duly interfaced to the Arduino. We are building this application even

for the visually challenged people to get them know and control the devices easily. The meter

reading is delivered to them using a text to speech process where the unit current is delivered

as a Voice Command. The Blind user can in return access the devices using the voice to text

process.

Access your Door with your own Finger print through your Smart phone without any external

devices required. Facial Recognition for the blind to recognize and detect the person standing

outside with a voice message. An Android Wear support with voice recognition and all other

same features to access the devices remotely.

If we are in home we can pair with Bluetooth which is enabled by the Bluetooth module. Then

open your mobile application and the user can have a control over the appliances and can

also able to customize. When we leave home switch the particular option made in the mobile

application. It automatically understands that the user leaves home and aborts the Bluetooth

connection. Then it refreshes the firebase database continuously to get the value to switch

on/off the particular appliance.

Conclusion:

Lot of work been reported in regards to controlling the appliances of home and also on

monitoring the electrical parameters towards hazard. Also work reporting in controlling the

appliance for energy consumption. So, with all these works reported, we here have developed

a better IoT system for Energy Management which takes the Humidity, Temperature and light

intensity into consideration and accordingly interfaced with Arduino Microcontrollers for

controlling the usage of appliance like speed of fan, light intensity rather than just switches

on or off. Also, the prototype system (Mobile Application) computes the current drawn from

each appliance based on appliance usage and send to cloud where total power consumed of

appliances computed against time. This information is computed all through the day and same

uploaded in cloud server too. This ultimately achieves in energy consumption of every

household resulting in Energy Management using IoT. we propose to extend the system for

controlling appliances like Refrigerator, Air cooler, Television etc. The presence of human only

will switch on the appliances. There can be also a manual control over the appliances. More

amount of power can be saved based on the lesser usage of the appliances.
