Automation is also involved in building management system in which lights, temperature, security devices and other appliances are controlled through a high degree of computer involvement. Home automation is not a new thing but the advanced automation system in nowadays require a big and expensive infrastructure. In this report, we have proposed a low cost, flexible secure automation system that can easily control TV, tube lights and fans from android based mobile phone using Bluetooth. Here HC-05 Bluetooth module and 8-bit microcontroller atmel89s52 is used for switching. A feedback circuit is also designed and implement to check the current status of the device after it receives the command from mobile phone.
Applications and Advantages of Arduino based device control using Bluetooth:
The LCD will also display the current state of the three bulbs. The proposed system has two main parts hardware and software. The hardware part consists of three main hardware components smartphone, Arduino board and Bluetooth module.
Symphony Link, for example, uses the Link Labs’ Radio module and the network specification incorporates star topology, wherein a set of end nodes communicates with a single gateway. This flexibility allows for a number of technical requirements to be met quickly, which is key in all home automation uses. Smart lighting allows you to control wall switches, blinds, and lamps, but how intuitive is a lighting control system?
Use case possibilities with Bluetooth low energy in IoT
The smart phone must be paired with the Bluetooth module. Either Bluetooth Terminal or BT Voice app can be used to pass the numeric commands. The change in the status of the appliance is updated on the LCD display and the LED indicating supply to the appliance starts glowing due to forward biasing. All you need to do is just open up the bluetooth manager in your Android smartphone and connect to the Linvor bluetooth module.
Undoubtedly, Wi-Fi is a fixture in nearly every home, so it goes without saying that a wide range of automated devices are already compatible with this standard and thus its advantages are numerous. Nearly everyone has access to Wi-Fi and many, if not all, consumers considering home automation systems have it installed. Wi-Fi was designed to handle large amounts of data traffic, so bandwidth to control your home devices is not an issue. From a security perspective, Wi-Fi Protected Access encryption has been shown to provide reasonable security for home users when activated and implemented.
Bluetooth Controlled Home Automation System
A relay can be used to control high voltage electronic devices such as motors as well as low voltageelectronic devicessuch as alight bulbor a fan. The Arduino board receives the user commands in the form of numbers from the smart phone through Bluetooth interface. These numbers are assigned to the home appliances and the appliances are toggled either ON or OFF on receiving the numeric command. The Arduino sketch looks for the numeric commands from the Bluetooth module and operates relays to switch appliances. Think how cool it would be if you are able to control your AC appliances just with a touch of your Android smartphone.
By automating your kitchen appliance and making them accessible from your smart device, you’re able to sever the electricity supplied to unused appliances and reduce your energy consumption and costs. Considering the number of appliances the average household owns; this could save a substantial amount of money over time. Throughout this guide, we will use an android smartphone that will connect to our Arduino development board. We will also use a Bluetooth terminal application to pair the two devices together.
The client module can communicate with host controller through a wireless device such as Bluetooth. Serial port Bluetooth module have a Bluetooth 2.0+EDR , 3Mbps modulation with complete 2.4GHZ radio transceiver and baseband. Using Bluetooth profile and android platform architecture different type of Bluetooth applications can be developed. Generally in today’s modern world human beings are addicted to using modern equipment. So here we can perform home automation by using an Android App and Bluetooth as a wireless communication medium. Home automation not only refers to reduce human efforts but also energy efficiency and time saving.
Internet-ready appliances are in high demand worldwide. That's why increasingly stores offer smart appliances to people looking to upgrade their homes. But as more smart devices become available, managing each smart device gets to be time-consuming. The most common applications of home automation are lighting control, HVAC, outdoor lawn irrigation, kitchen appliances, and security systems.
Conversely, the system will be alerted to dry conditions and supply the necessary amount of nourishment, without over-watering. There are two types of pins on the whole 16×2 LCD module. Some pins are used to send to 16×2 LCD and some are command pins. In other words, every pin has a role in controlling a single pixel on the display.16 x 2 LCD has sixteen columns and two rows. That means, it can display sixteen characters per row and it has two such rows. The numbers are transferred to the interfaced Bluetooth module from the paired smart phone.
We have come up with a new system called Arduino based home automation using Bluetooth. This system is super-cost effective and can give the user, the ability to control any electronic device without even spending on the remote control. This project helps the user to control all the electronic devices using his/her smartphone. The AT89c52 is low power, high performance 8 bit microcontroller with 8k bytes programmable flash memory. The device is manufactured using Atmel high-density nonvolatile memory technology and is compatible with the industry standard 80c51 instruction set pin output.
The standard open-source library for interfacing LCD with Arduino UNO is used in the project. The library works as expected and needs no changes or modifications. HC-05 is low power 1.8V operation and is easy to use with Bluetooth SPP and 3Mbps modulation with complete 2.4GHZ radio transceiver and base band. To be able to design a product using the current technology that will be beneficial to the lives of others is a huge contribution to the community. The Specification, Design, and Implementation of a Home Automation System using real-world sensor inputs as operands. Application is connected after disconnect of the Bluetooth.
3.3V TX output of HC-05 is directly connected to the RX input of PIC microcontroller. As 3.3V will be taken as LOGIC HIGH as per 5V TTL specifications. The Bluetooth module used in this project is HC-05 Linvor Bluetooth module. It is an easy- to-use Bluetooth serial port protocol module, designed for a transparent wireless serial connection set-up. The module has 34 PINS for configuration/interfacing of Bluetooth module with microcontrollers.
The supply from the battery will be regulated to 5V and 12V using 7805 and 7812 ICs. The pin 1 of both the voltage regulator ICs will be connected to the anode of the battery and pin 2 of both ICs will be connected to ground. The respective voltage outputs will be drawn from pin 3 of the respective voltage regulator ICs. An LED along with a 10K Ω pull-up resistor can also be connected between common ground and output pin to get a visual hint of supply continuity. Output of PIC 16F876A microcontroller is connected load unit i.e., home appliances via driver IC 2803 and relay unit. Driver drives the respective load for the respective received command via relay as a switching unit.
