Build an IoT App With InfluxDB

The IoT Center workshop aims to improve a simple IoT application called IoT Center. Participants will install the application, interact with InfluxDB, use a JavaScript client library, add a new widget to the IoT Center dashboard, and learn about monitoring Node.js applications.

The presenter of the IoT Center workshop is Miroslav Maleha, a product manager at Bonitoo.

InfluxDB is a time series database platform capable of handling large amounts of timestamped data. It supports data accumulation, storage, visualization, and analysis, and offers features like alerts and notifications. InfluxDB is available as both an open-source and a cloud version.

The main functions of the IoT Center application are registration of IoT devices, generating data through a virtual device, and visualizing data on a dashboard.

To install the IoT Center, you need Git, Node.js, and Yarn Package Manager.

To create an InfluxDB Cloud account, visit cloud2.influxdata.com, choose to register via Google, Microsoft, or email, verify your email if needed, select a cloud service provider, enter your company name, agree to the service agreement, and select the free plan.

The virtual device in the IoT Center emulates a real IoT device, allowing users to generate and visualize data without needing actual IoT devices.

To visualize IoT device location data in the IoT Center, you need to modify the dashboard.page.tsx file to query latitude and longitude data from InfluxDB and use the Leaflet library to display the data on a map.

The InfluxDB JavaScript client library is used for querying and writing data to InfluxDB. It supports both server-side and browser-side operations and offers features like data buffering and error handling.

You can monitor a Node.js application with the IoT Center by using functions to measure CPU and memory usage, capturing HTTP request response times, and creating custom events. You can then visualize this data using predefined templates in InfluxDB.
