Development of IoT based solution for monitoring & controlling of loads using Google Assistant with Home Security System

Abstract

The main aim of this project is to make a cost effective device which is used to monitor and control the loads by using simple voice commands. Previously we have ALEXA, SIRI & GOOGLE HOME which makes us more expensive. Even now when technology is handy enough only the well to do people of the society are blessed with these new smart home devices, as these devices costs are a bit high. However, not everyone is wealthy enough to be able to afford a human assistant, or some smart home kit. Hence, the need for finding an inexpensive and smart assistant for normal families keeps growing. This project proposes such inexpensive system. It uses the Google Assistant, the IFTTT application, the remoteme.org cloud application and the NodeMCU microcontroller as the major components along with a relay board comprising of 4 relays along with different sensors are working in this. Natural language voice is used to give commands to the Google Assistant All of the components are connected over the internet using Wi-Fi which puts this system under the IoT. And also we monitor data in this that is we using the different sensors like IR sensors, LDR (Light Emitting Diode) sensors etc; Not only to monitor and control the Loads but also providing the Security System to the Home, whenever the thief or the visitor enter into the room the owners will get push notification in their smart phone and also capturing the photos of visitors and uploaded to the Google Drive.
