Node.js Websockets server Sensor data handling – How to

In this video, we will be building a real-time data streaming server using node.js and websockets. We will be connecting AZ-envy development boards, which are based on the ESP8266 microcontroller, as sensor modules to the server. These development boards will transmit the data to any clients connected via websockets. This setup is perfect for applications that require live updates, such as monitoring systems or IoT devices.

We will start by setting up the node.js server and installing the necessary libraries for websocket communication. Next, we will connect the AZ-envy development boards and configure them to send data to the server. Finally, we will build a simple client interface to display the live data as it streams in.

By the end of this tutorial, you will have a solid understanding of how to build a websocket server and stream data in real-time using AZ-envy development boards based on the ESP8266 microcontroller. Let’s get started!
