Install the Influx database on the Raspberry PiĪ. Environmental consultants, building managers, energy auditors, research scientists, and many more professionals all rely on data loggers. A data logger may be a single-unit, stand-alone device with internal sensors, which fits in the palm of a hand, or it may be a multi-channel data collection instrument equipped with one or more external sensors.ĭata loggers are valuable tools for anyone who wants to continuously monitor conditions without having to be on site. They can be deployed indoors, outdoors, and underwater, and can record data for up to years at a time, unattended.
Grafana is an open-source, general purpose dashboard and graph composer, which runs as a web application.ĭata loggers are typically compact, battery-powered devices equipped with an internal microprocessor, data storage, and one or more sensors. In this simple datalogger example, we want to try out the Grafana application. The data stored by our datalogger could also been written to a file as comma separated data and then import that file in excel and made some nice graphs and presentations. Grafana Presenting the datalogger results:
That will be discussed in a future article. You could store the data another place as in the cloud or on an external hard drive or usb stick. In our simple datalogger example, the data is stored on the SD card hence make sure you use a good quality type of card as it will be written to many times.
InfluxDB also offers a SQL-like query language for interacting with data. It is possible to conserve space on your machine by configuring InfluxDB to keep data for a defined length of time, automatically expiring and deleting any unwanted data from the system. InfluxDB is a custom high performance datastore written specifically for timestamped data, including DevOps monitoring, application metrics, IoT sensor data, & real-time analytics.
#KEPWARE DATALOGGER SERIES#
InfluxDB is a Time Series Database built from the ground up to handle high write & query loads. We have decided to use the Influxdb database to organize and store our data. Our simple datalogger needs some kind of place to organize and store the datalogger measurement samples.
#KEPWARE DATALOGGER DRIVER#
Simulator Driver for simulating live data.Support for store and forward, which prevents data loss when the SQL server is unavailable.Support for the CSV import/export of logged items.Contains a “_LogDataBit” System Tag that allows client applications to trigger DataLogger.Ability to use Start/Stop Snapshots without requiring that the Log on Static Internal or Log on Data Change Trigger behaviors be enabled.Support for an optional NumericID field for logged items.Drag and drop support for adding OPC data items (tags).User-friendly installation and configuration.Support for any ODBC-compliant database management system.DataLogger’s tight integration with KEPServerEX provides substantial, unique benefits such as simple installation, high-efficiency performance, and easy browsing of tags in the OPC browse space. DataLogger Plug-In KEPServerEX – Communications Platform The DataLogger Plug-In is an easy-to-configure application that logs data from an OPC server to any ODBC-compliant database.
