![]() Connect to the pins according to the code. The input pins IN1, IN2 of the 2 channel relay are connected to digital pins of the NodeMCU. 4 Circuit Diagram for Home Automation With AlexaĬonnect all the components as shown in the above circuit diagram. You can control computers, peripherals or other powered devices from across the office or across the world. Devices can be remotely powered on or off with commands coming from Clock Watch Enterprise delivered over a local or wide area network. With it you can remotely control devices over a network or the internet. REALY MODULE: The Relay module is a separated hardware device used for remote device switching. Echo devices connect to the voice-controlled intelligent personal assistant service Alexa, which will respond when you say “Alexa”. AMAZON ECHO DOT: Amazon Echo (shortened to Echo) is a brand of smart speakers developed by Amazon. Both the firmware and prototyping board designs are open source. It initially included firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which was based on the ESP-12 module and support for the ESP32 32-bit MCU was added later. NODEMCU: NodeMCU is a low-cost open source IoT platform. The command is given by the user to Alexa and then NodeMcu read the data through Wi-Fi and decides the switching action of electrical devices connected to it through Relays where it acts as fuse. The controller for the automation in this project is NodeMcu. We use the Amazon Echo to develop a skill that will communicate with our circuit to control our devices. So, the objective of our product is to provide a cheap and inexpensive way to control non-smart devices using the power of voice.Īmazon Echo is a smart speaker that has been developed by the Amazon Company that can be used to control a lot of smart devices. To control smart devices using Alexa is very simple, but altering non-smart devices to smart devices are not affordable by everyone. ![]() It can also control several smart devices using different skills present in it. The device connects to the voice controlled personal assistant service Alexa, which responds to the word or name, “Alexa.” The device is capable of voice interaction, play music, making to-do lists, sets alarm, streaming podcasts, and providing weather, traffic, and other real time information. To achieve this in a simpler way Amazon Echo is used which is a voice-enabled wireless speaker developed by Amazon. This can be achieved using many technologies present right now. ![]() This will support inter connectivity of numerous smart homes for a better resource utilization in wider area. Home automation interfaced with the Internet of Things (IoT) provides greater flexibility in controlling household objects in a wider aspect. The household objects should be intelligently interconnected as well as provide information for better operations. ![]() Home automation means the monitoring, and control of household electronic devices intelligently for effective usages. This has a greater importance than any other technologies due to its user-friendly nature.Īn essential part in Automation is Home automation. The hunger for automation brought many changes in the present technologies. Automation is frequently spelled in the field of electronics. ![]()
