Design And Implementation Of IoT Access Point For Smart Home
Project Area of Specialization Internet of ThingsProject Summary This project proposes the integration of ZigBee communication, Wi-Fi communication, and Internet connection capabilities onto a traditional Wi-Fi AP by combining the AP with ZigBee standard. With the proposed approach, the original Wi-Fi AP can be upgraded to an IoT AP. IoT AP adaptively provides negotiation of channel usages between Wi-Fi network and ZigBee networks and help ZigBee network to allocate channel in a shorter response time.Wi-Fi interference can compete with other Wi-Fi devices and reserve the allocated bandwidth resource for ZigBee network. This function fully resolves the existing problem of unbalanced resource competition between Wi-Fi and ZigBee interferences. Project ObjectivesThe main objective of this project is to build a smart home device which can be used to control the home appliances via internet. The home automation device that you build can be integrated with almost all the home appliances and can be used to control them remotely from any part of the world.
To facilitate the wireless connectivity with the system, the Zigbee S2 will be embedded with a WiFi module. This establishes the internet connection to the system and all the home appliances can in turn be connected and controlled by internet. The device can also be connected to an Android App which you can develop on your own using some applications like MIT App inventor etc. By using this app, you will be able to monitor and control the home appliances from any part of the world with ease.
You can also include a PIR sensor with this project to make it switch ON automatically the appliances whenever a person enters the room and switch OFF the appliances whenever the person leaves the room
Project Implementation Method- Step 1: In order to establish connection between the client and the server, the Wifi option in the Smartphone is enabled
- Step 2: It is connected to the Wifi module of the system
- Step 3: Each electronic/electrical appliance in the system is connected to the digital pins on the ZigBee S2 Board
- Step 4: A Relay is used for connecting each device to the Arduino, which helps in converting high Voltage supply to low voltage
- Step 5: A C-program is loaded on to the microprocessor chip on the Arduino Uno Board which specifies what action is to be performed on receiving particular inputs
- Step 6: An Android Application has been developed which enables the end user to monitor and control the appliances from any remote location
- Step 7: Socket Programming has been used to achieve client-server communication
- Step 8: Successful controlling and monitoring of appliances
You need to use USB to serial converter that allows the system operation at 3.3V. You can connect the pins of the ESP32 module via jumper wires to the corresponding pins on the USB. The ZigBee S2 connected with ESP32 WiFi module is used to implement the micro web server for the home gateway. A conventional light switch will be integrated with the ZigBee S2 using relay driver module to demonstrate the switching capability. This hardware architecture is very flexible and allows other home appliances and devices to be seamlessly integrated with minimal changes
Benefits of the Project- Increase your independence and give you greater control of your home environment..
- Save you time and effort.
- Improve your personal safety.
- Reduce your heating and cooling costs.
- Increase your home’s energy efficiency.
- Alert you audibly and visually to emergency situations.
- Allow you to monitor your home while you are away
- Managing all of your home devices from one place. The convenience factor here is enormous. Being able to keep all of the technology in your home connected through one interface is a massive step forward for technology and home management.
- Maximizing home security. When you incorporate security and surveillance features in your smart home network, your home security can skyrocke. There are tons of options here -- only a few dozen of which are currently being explored. For example, home automation systems can connect motion detectors, surveillance cameras, automated switch home appiances On/Off
Final deliverable of our project is to switch On/Off the home appliances by using IOT access point.
we integrate different types of hardware devices and components to build this system to control the home appliances.we used ESP32 module with ZigBee S2 that establish connection between mobile and ZigBee S2 coordinator. ZigBe S2 coordinator passes the cmmands of user to ZigBee Router and the relay switch IC connect with ZigBee S2 router that switch On/Off the the home appliances
