3. Abstract T his project presents the overall design of Home Automation System with low cost and wireless system. It specifically focuses on the development of an IOT based home automation system that is able to control various components via internet or be automatically programmed to operate from ambient conditio n. We used Node MCU, a popular open source IOT platform, to execute the process of automation .

4. INTRODUCTION Control most of your home appliances using laptop or phones remotely. Get feedback about the status of your home via internet. Provide an easily and comfortable way to control your home devices from any place.

5. OVERVIEW OF PROJECT The following describes the process of creating an account in Blynk application and generating unique ID against a particular device. This ID acts as an identifier for the particular device on the Blynk server.

8. Module description Node Mcu NodeMCU is an open-source firmware and development kit that helps you to prototype or build IoT products. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module.

9. RELAY A power relay module is an electrical switch that is operated by an electromagnet. The electromagnet is activated by a separate low-power signal from a micro controller.

10. Jumper wires A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard.

11. BULB A bulb is the glass part of an electric lamp, which gives out light when electricity passes through it.

13. WORKING OPERATION Node MCU is an open source IOT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “Node MCU” by default refers to the firmware rather than the development kits. The firmware uses the Lua scripting language. It is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266.

14. ADVANTAGES SAVE MONEY AND INCREASES CONVENIENCE SAVE TIME HIGH RELABILIATY EASY TO CONTROL

15. APPLICATIONS SMART HOMES HEALTH CARE AGRICULTURE INDUSTRIES

16. RESULT The Blynk application was also successful in displaying the status of every application.

17. Output

18. CONCLUSTION By using this we can reduce cost and can control or monitoring the home appliances from anywhere Can create wireless network in house and reduce wiring. Hence, this system is scalable and flexible.

19. FUTURE SCOPE Using this system as framework, the system can be expanded to include various other options which could include home security feature like capturing the photo of a person moving around the house and storing it onto the cloud. This will reduce the data storage than using the CCTV camera which will record all the time and stores it. The system can be expanded for energy monitoring
