Internet of Things using Node-Red and alexa

摘要

The Internet of Things (IoT) means learning and interacting with millions of things including services, sensors, actuators, and many other objects on the Internet. This project enhances on how far IoT can connect devices on different platforms. This will effortlessly help humans in various fields like Home automation, networking, data monitoring and others. The evolution of human-machine user interface has drastically changed over the years. The path of advancement has been through keyboard, mouse, touch and now it is Voice. This new user interface can be achieved by Alexa Voice Service. Currently, we have very few devices that can be controlled using Alexa. Some of the examples are Philips Hue, WeMo, and Wink. But these are limited to certain hardware. The initial installation and maintenance is expensive. The proposed system connects and controls most of the IoT devices connected to it using Voice. As the number of devices on the cloud increase, there is need for updating firmware more frequently. This is tedious. It involves taking out the installed devices, changing the code and flashing it again. To overcome these, processing of data and response can be done elsewhere. Node-Red, a visual wiring tool helps in connecting devices with ease resulting in effortless and rapid connection setups.
