Thresholds

The Base Station WebGUI allows users to configure threshold values for connected sensors to monitor environmental conditions and indicate when predefined limits are exceeded.

Thresholds define minimum and maximum acceptable values for sensor measurements such as temperature, CO₂, humidity, or radon. When a sensor reading crosses a configured threshold, the system can indicate an alert in the WebGUI and forward the threshold status to integrated systems or configured email notifications.

When a threshold value is changed in the WebGUI, the new value is applied immediately on the base station. The change affects real-time monitoring, alarm evaluation, and data forwarded to external systems. A base station restart is not required.

Thresholds are configured per sensor. Changes apply only to the selected sensor and do not affect other sensors connected to the base station. Historical data is not recalculated after a threshold change and remains unchanged.

To perform a change of thresholds, you need to go to the Sensors tab in WebGUI.

Then choose the sensor you would like to change the thresholds. Click on it to open sensor settings.

To change thresholds, you need to drag parameters.

To save the parameters you have set, you need to press the Save button, which will turn blue, after you have unsaved changes.

Threshold settings are stored locally on the base station. If the base station is connected to Aranet Cloud, updated threshold values may be synchronized and reflected in cloud dashboards and alerts. If the base station is offline, thresholds remain active locally and will synchronize with the cloud once connectivity is restored.

Changing thresholds does not affect sensor calibration or measurement accuracy.
