Concept

The aim of this demo is to show how simple it is to connect sensor data to the cloud  and vise verse. The demo uses NIO-100 to receive measuring data from available multimeter via serial interface, decodes the information and upload an averaged measured data to the cloud.  A web application uses PHP and JS / HTML5 to store / recall the data as well as to visualize it. The setup is shown on the picture below.

nio 100

NIO 100 is designed by NEXCOM as an IoT (Internet of Thing) gateway for cloud application specifically focused in industrial field, collects sensor data via RS232/485/DIO and transmitting data to cloud by 3G, WiFi or Ethernet. The NIO 100 has wide range power inputs of 9~36V DC suitable for industrial environment.

The NIO 100 based on Intel Quark CPU and comes with either WindRiver or Yocto OS, including also and advanced application development and run time environment called IoT Studio. Data sheet for NIO 100 can be found here.

IoT studio

 The IoT Studio is a based on the Node Red project - a visual tool for wiring the Internet of Things created bi IBM® Emerging Technology.

Node Red is running in a JavaScript environment supplied by node.js®.

Node.js® is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

IoT Studio Application

The picture above shows the IoT Studio application used to collect the data, analyze it and load it up to the server. some of the boxes (those marked with f) contain JavaScript function to manipulate the data, others create connection to the multimeter via COM port, generate timing or send data to the cloud (in this case via HTTP request) or for debug purposes.
