Receive and store LoRa sensor data from TTN using a Raspberry Pi (part 2)

Back in the first part of this series, we detailed the process of building a simple LoRa-connected weather station to monitor temperature, humidity, and pressure, and send the readings to The Things Stack (TTS). In this second part, we’re going to take a look at how you can capture that data, record it and produce a dashboard and graphs to visualize the data. Note: 28th June 2021: The Things…

Aggregate data from a fleet of sensors with balenaSense and InfluxDB

UPDATE on 07 July 2021: Note that the latest version of balenaSense (v2) does not allow data from multiple sensors to be aggregated using the steps outlined in this post. To aggregate data in v2, see our updated guide. Back in March we wrote about balenaSense, our project to monitor air quality with a Raspberry Pi, Grafana and InfluxDB. Lots of you have been using this project and giving great…

Sensors and Data Logging with Embedded Linux - The Ultimate Guide Part 3: Multi-Device Sensor Dashboard

This is the third and final part in a series that dives into logging sensor data with embedded Linux, containers, and Balena's platform. The first part was a deep dive into how sensors can be read by embedded Linux, and the second part explored how to collect and graph sensor data with a TIG stack of services. This third part builds on the first and second parts to explore building a multi-device…

Sensors and Data Logging with Embedded Linux - The Ultimate Guide Part 2: Build A Sensor Dashboard

This is the second in a three-part series that dives into logging sensor data with embedded Linux, containers, and Balena's platform. The first part was a deep dive into how sensors can be read by embedded Linux. This second part builds on the first part to add a database and web dashboard for viewing sensor data. You'll learn about multi-container applications in Balena and how to use services…

Sensors and Data Logging with Embedded Linux - The Ultimate Guide Part 1

This project is the first in a three-part series that explores in depth how to log data from sensors with embedded Linux and a container-based architecture. You'll learn how to connect a sensor to a Linux board and read data from it, how to store and graph sensor data with modern service tools like InfluxDB and Grafana, and how to scale the application up to many devices and sensors. This first…
