Smart building and home mautomation based on voice and gestures

Abstract

Voice Based Home Automation System using ESP8266 NodeMCU. It is the idea which corresponds to the new era of automation and technology. The main aim of the home automation system is to make life easier. Mobile devices are very common among everyone due to its user friendly interface and portability features. In this project we aim to control electrical home appliances by android voice commands using Wi-Fi as communication protocol and Android device and to add some other application to make a smart building. This system is basically designed for the visually challenged people to aid them in operating the home appliances individually. In this system MEMS accelerometer is used to detect hand motion and transmitted using Radio Frequency (RF). This proposed system used to control the function of various home appliances. This paper presents a low cost and 3 axis wireless accelerometers based system to control the Home Electronic devices. Advancement in industrialization leaves the parking management system outdated. Traffic condition in foreign countries are homogeneous whereas India’s traffic condition is heterogeneous which makes real-time management at parking lot difficult. Traffic congestion at parking lot has become often, that people cannot even find the place to park their vehicle especially in large companies where first come first serve method is used for parking vehicle. In nutshell, parking condition needs to be improved by introducing Internet of Things (IoT) to parking lots. With the help of Microcontrollers and Image processing. The physically challenged people have many difficulties in their day to day life. Mostly to control the home appliances is very difficult task for them and some of the people are still illiterate. In order to aid them, gesture based control of home appliances without the sign language is proposed in this report. The various components used are Flex sensor, XBee Transceiver and DC motor. The flex sensor is calibrated initially for every position using microcontroller. The data from flex sensor are transferred to wireless transmitter through microcontroller. It is received by wireless receiver and send to microcontroller which controls home appliances. The gesture made by the physically challenged people is also displayed in LCD.
