III. OUR PROPOSED METHOD
There aren't any users who don’t want to feature more features over the prevailing system which provides more elasticity and runs with some general applications sort of a smart phone. Our system is intended in such the way that abstains from the drawbacks of the present system. The developed method gives more security, comfort, and adaptability. The aim of our proposed method is to style and to implement an occasional cost and open-source home automation that’s able to lead most of the house and sustain the house automation system. To use wireless reliable technology to interconnect many modules to the server of the house automation system, as a result, the proposed system gives more flexibility. this technique will reduce the expansion cost; will augment the elasticity of advancement. Through DHT22 sensor we are able to measure temperature and humidity. The temperature value is employed to tour on the fan if the worth of temperature is beyond the given threshold. The user can either activate or off this automation using the android/ IOS application.
IV. SYSTEM DESIGN
NodeMCU is an open-source firmware that open source prototyping board designs are available. It’s sort of a brain. Its primary advantage is low cost and Wi-Fi capabilities. the most a part of home automation system is NodeMCU. Its very useful for learning IoT. We are going to use Micro Python to program our NodeMCU which is a variation of python built for small low power and low processing requirements.
B. Sensors and NodeMCU
The DHT22 Temperature and humidity sensor module is employed for reading temperature and humidity values. The DHT sensors are manufactured from two parts, a capacitive humidity sensor and a thermistor. there's also a awfully basic chip inside that does some analog to digital conversion and spits out a digital signal with the temperature and humidity. The digital signal is fairly easy to read using any microcontroller.
We upload the temperature value to Adafruit Server through MQTT communication therefore the user can see these values from android/IOS application. We use the temperature value to show on fan when the temperature reaches a specific degree.
We even have TTP223 capacitive touch sensor that the user can use to show off or on the values of individual electrical components. TTP223 touch sensor is that the quite common sensor that's want to control the system with human interface with the system. TTP capacitive touch sensor, widely used sensor in automation and project. Touch Sensor are used for controlling the system or device physically with the touch response of body to sensor.
C. Architecture of Our Proposed IoT System
The proposed IoT architecture system consists of Network and Transport Layer, electrical circuit Layer, Application and Presentation layer, Physical Layer.
IoT gateway router, device manager and lots of contact protocols are a part of the information link layer. All the controlling devices are included within the physical layer section. For controlling many devices, an online portal is meant an internet page at the appliance and presentation layer.
The de-vices may also be controlled by making an app on a transportable. the online portal and mobile app do similar works. The proposed system IoT layer is shown in figure 2.

A. Hardware implementation
The most important components of hardware parts are NodeMCU, DHT22, 4 Channel Relay, TTP223 Capacitive Touch Sensor. Many sensors are interfaced with NodeMCU through Micro python artificial language and also the output is seen in Web and android/IOS application. The circuit diagram is given below.
???????B. Software Implementation
Install micro-python on NodeMCU using Thonny Software. Then we write a code using micro python artificial language to remotely control lights, fan, switches and other appliances.
We use the third-party server as Adafruit for this prototype except for the business purpose we use our server. We connect the code between NodeMCU and therefore the third-party live server. The NodeMCU is interfaced with many sensors like DHT22 Temperature and humidity sensor and TTP223 Capacitive touch sensor. These sensors are continuously updated data to the server every 10 sec. this will easily change by the user. We develop an Android/IOS app using Flutter to manage and monitoring home appliances. First, the app connects to the server and sends data to the server from the user itinerant via the net when the user presses the visual button during this android app. NodeMCU reads the information from the server and executes this instruction. Also, the Android app gets updated JSON data from the live server and displayed on the mobile screen.
???????C. Mobile Application
Smart phone may be accessed on the house automation system through IP addresses. io.adafruit.com could be a hosted server of the smart phone and therefore the remote user sends and receives data through this server. Through a sensible phone and IP address, the user can check the status and instruct the devices. we've developed an internet portal which will also control and monitor the devices. The device first receives the state of all topics and updates the information on the app. Then we are able to view the status of the sunshine, fan, and switches within the rooms where they're turned ON/OFF. we are able to see all the devices and that we can select any devices which we wish to regulate. Figure 4 shows the controlling app, control devices and their status (on/off/temperatures and humidity).
The Figure 5 shows the experimental testing of temperature and humidity sensor working prototype. When temperature value is increased beyond threshold level then fan is automatically switched ON without human interruption. The web application controls the light, fan, switches relays through network from remote location. The smart phone, laptop and personal computers are used for accessing web application over the network. This proposed model controls the relays over the network from remote location.
Figure 4 shows the mobile application designed for the user. The app first loads the previous values from Adafruit server so load the info on app. Then the user can control the devices remotely using network through Adafruit server.
The latent period for our commands is well within the allowable range and might be controlled easily. We designed an easy system for the user to manage the electrical appliances in his home with a coffee cost model which might be expanded to the users’ requirements
We would like to thank the management and staff of MVJ College of Engineering, Bangalore, India for all the help and support provided by them.
It is evident from this project work that a personal control home automation system will be cheaply made up of low-cost locally available components and may be wont to control multifarious home appliances starting from the protection lamps, the tv to the air-con system and even the whole house lighting system. And better still, the components required are so small and few that they will be packaged into a tiny low inconspicuous container. The designed home automation system was tested several times and authorized to regulate different home appliances employed in the lighting system, air-con system, home entertainment system and plenty of more. Hence, this technique is scalable and versatile
