In another research work, XBee based home automation system introduced for handicapped and elderly people. XBee transceivers was used for wireless communication between the master control panel board and the remote control device. Our modern life today is simply over dependent on technology and its application.

There are many such technologies by which many more difficulties are entering. This is a special issue which examines the most recent contributions of IoT platform as well as in the progress of the trending technologies. A statement from IoT is that, monitor and control any technology from anywhere, anytime, wireless, fastest. Automation means all the appliances connected to the system can control by the Bluetooth-based app which can run on any mobile phone. You can make this application by yourself by using the MIT app inventor too. I hope you all will succeed to make this project by yourself you have to read and follow all the instructions given in the article.

Home Automation System Using Arduino and HC-05 Bluetooth Module

You can change in design and codes or also can add more buttons according to your needs. Please send me all code and progmmaing for display,connection diahram all information u have. The table below shows the commands that we will send by our mobile on the Bluetooth application and the response that will be received. The diagram shows the pin configuration of a 16×2 LCD display. We will use a 16×2 LCD in our project to display the states of the appliances. To connect a 16×2 LCD with Arduino we will require an additional 10k potentiometer as well.

It uses sonar to calculate the distance from a physical objects. It has an excellent range of object detection from 2 cm to 400 cm with high accuracy. The ultrasonic sensors calculate the physical object's distance by transmitting ultrasonic wave and then detects its reflection wave.

Introduction: Home Automation Using Arduino and Bluetooth

To establish a Bluetooth connection, we will use the HC-05 Bluetooth module. When we pressed any button of the App, the App sends a unique load value according to the button. The HC-05 Bluetooth Module received this unique load value and send it to the Arduino. Then, the Arduino compares the value with the predefined value of the button.

Moreover, also specify the Arduino digital pins connected with TX and RX pins of the HC-05 module. Specify the Arduino pins connected with IN1, IN2, and IN3 of 4 Channel Relay Module. ELECTRODUINO.COM is a free online platform, it provides A Better Way to Learn Electronics.

Remember To Disconnect The VCC Pin Of HC-05 Before Uploading Code.

DHT22 sensor is used for the measurement of temperature and humidity, room temperature and Humidity will be displayed through Google assistant. This system consists of Python as the main programming language by default, provided by Raspberry Pi. In the app, there are many buttons that send some variable when we press those specific buttons. Then the Arduino starts to compare the received data with the Database and generates the output signals accordingly. By sending the different commands we can operate different appliances.

If this value is matching then Arduino sends operating voltage to the relay module. Home Automation Using Arduino and Bluetooth is an IoT project to control our home appliances like light, fan, cooler, etc. from a Smartphone. In this project, we use Arduino Uno and HC-05 Bluetooth Module and we give the command from our smartphone. To add Bluetooth functionality, we will use the HC-05 Bluetooth module.

Likewise, the green and blue bulbs will be controlled similarly with commands ‘blue on’, ‘blue off’, ‘green on’ and ‘green off’. Next, we declare the Arduino pins that are connected with the LCD. This line creates a LiquidCrystal object and lcd is a name of the object that we are going to use to call LCD functions. The pin configuration of the PIR sensor is shown in the figure. PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output.

Of technologies influence us to use smartphones to remotely control the home appliances. An automated devices has ability to work with versatility, diligence and with lowest error rate. The idea of home automation system is a significant issue for Researchers and home appliances companies. Automation system not only helps to decrease the human labor but it also saves time and energy.

Here IoT comes across as a technology which transforms the way we perceive our surroundings. IoT is considered to be a network of interconnected physical objects/things around us that communicate with each other over the Internet. These days, the need for efficient controlling of appliances to minimize power wastage is important as fossils and non-renewable sources of energy are plummeting. So, a smart home system has been developed to monitor and control home appliances remotely from anywhere. This has been executed on a virtual simulator namely Proteus where the hardware circuitry has been designed. Blynk app has been used to send the user's command to the circuit through the local cloud server connected with Arduino and Bluetooth module.

It monitors the power consumption of every electrical device at uniform interim of time. This data makes us conscious on the amount of electricity being consumed, which in turn leads to a ecofriendly life. IDE stands for Integrated Development Environment, entire programming for proposed system is done in Arduino IDE tool. Baud rate is set to 9600 bits per second for serial communication between Arduino board and smartphone. Arduino IDE command "Serial. A vailable 0" is used to receive data serially from smartphone and "Serial.printlnO" command is used to transmit data serially from Arduino board to smartphone.

In the current strategy taking a reading and creating bills is manual works. Power appropriations are one of the largest difficulties in India. Periodically user not spent bills on period so the electricity committee worker cut the power supply manually. In this topic sometimes fraud is done by the user or that employee which leads to the loss of electricity committee.
