Summary
Home automation is a topic which gaining popularity day by day, because of large advantages. Smart home is one of the Internet of Things (IoT) applications that facilitates the control of home appliances over the Internet using automation system. In this project we propose a low-cost esp32 board based automation system for Smart Home (SH) in order to monitor and control home appliances using esp32 based application. An Arduino board is utilized to build the automation system. In addition, some sensors are used to monitor and control the fan and light in home. A relay board is exploited to connect the Home automation system with home under controlled appliances. The proposed automation system, can easily and efficiently control the electrical appliances via sensors and Bluetooth and wifi application. The internet of things (IoT) is the network of physical objects or “Things” embedded with electronics, sensors and network connectivity, which enable these objects to collect and exchanging data. IoT allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunity for more direct integration between the physical world and computer based system, and resulting in improve efficiency, accuracy and economic benefits.
Further, in the project will be design a refrigrator health montior system particularly the electricity flow and opening of the door of refrigrator will be monitor through IoT. The sensor will be connected with small switch gadget and incase of unsmooth flow of elecricity or open of the refrigratory door for long peroid the signal will be generated and switch off the flow of electricity and send the the message to the user smart phone
The objective of this project is to implement a low cost , reliable and scalable home automation system that can be used to remotely switch on or off any household appliance
• To save energy proper management of electricity distribution.
• To show the effective way for power utilization and conservation.
• To control and monitor any operating system.
• To make power usage low and conservation more effective.
• To make smart and intelligent usage of energy and its conservation in home appliances
Implementation Method
The Technology behind this project is IoT(internet of thing). Arduino along with Wi-Fi module Esp32 and raspberry pi 4 with 4gb Ram in home automation system for the controlling of home appliances with help of this gadget we will facility the home especially rooms like if you say turn on light the light will on and you say turn off light the light will turn off you can also control the device thought mobile we are also controlling the refrigerator . The following steps will be consider during methodology.
Step-1 Review the Literature and study the existing system
Step-2 Equipment will be configuration and installation.
Step-3 Configuration of Sensors, and board
Step-4 Connected the Sensor with Raspberry Pi and generate the data from multiple devices. The data will be extracted and stored in ThingSpeak.
Step-5 Software design in android.
Step-6 The data connected will transfer to the cloud based system and the user can extract in his/her smart phone.
Step-7. Testing of the System and Remove the errors in real time.
