Dräger
The Dräger X-node gas measuring device measures temperature, humidity, air pressure, and various gases such as CO2, CO, O2, and H2S. The associated app connects to the device via Bluetooth and displays real-time measurements. Alarm thresholds, LoRa connections, and other parameters can be configured via the app. Additionally, a logger visualizes past measurement data and allows for the display of minimum and maximum values.

The Dräger App
Highlights at a Glance
Connections
The X-node connects via Bluetooth Low Energy using the UART service. This technical challenge is efficiently managed to ensure stable and smooth communication with the hardware.
Various Sensors
The X-node supports different sensors for gas measurement. The app offers customized options for each connected sensor to ensure precise and specific data acquisition.
Logger
Past measured values are clearly presented in a diagram that directly displays the minimum and maximum values, enabling clear and understandable data analysis.
Firmware Update
Through the DFU standard, the app can continuously supply the X-node with new firmware versions, ensuring continuous development and optimization of the device.
Set Location
A location for the X-node can be set via the app, which is particularly helpful when multiple devices are in use on a site. This simplifies management and overview.
Calibration
To maintain the accuracy of the gas sensors, a calibration is offered via the app. This function ensures that the sensors operate precisely even after extended use.
