During a hackathon at Grafana Labs, Richard "RichiH" Hartmann invested time in updating Kraken, a project for reading sensor data, to support modern hardware and libraries. The blog post focuses on using the Bosch BME 680 sensor, which measures air temperature, humidity, pressure, and air quality, as a beginner-friendly project for monitoring environments such as home offices or cellars. The process involves using Grafana Cloud, a managed observability platform, though it is also compatible with local Prometheus setups. Hartmann provides a detailed guide on assembling the necessary components, such as the ESP32 development board and the Bosch BME sensors, and coding them using the Arduino IDE to send data to Grafana Cloud. The article emphasizes the importance of using safe soldering practices and offers advice on setting up dashboards and alerts in Grafana Cloud to analyze the collected data. Additionally, Grafana Labs is actively hiring and encourages those interested in participating in open-ended hackathons to explore career opportunities with them.
