Finding and Setting Sampling Interval
A sampling interval defines how often the device samples the relevant sensor for data. For example, a 5-minute sampling interval means the device collects data from the sensor every 5 minutes.
Sampling intervals are defined at the group level, so all channels in a group share the same interval. Modifying the interval for one channel will apply the change to every channel in the group.
Key Considerations
The minimum sampling interval depends on the sensor's capabilities.
Typical intervals range from 5 minutes to hourly, but shorter intervals (e.g., 1 minute) are possible if the device uses an external power supply to minimize battery depletion.
Adjusting the sampling interval affects the frequency of data collection and battery usage.
Steps to Find and Set a Sampling Interval
Finding the Sampling Interval
In the left pane, click Devices.
In the Sites Tree pane, select the relevant device.
In the right pane, go to the Configuration tab to view the Stream Management Table.
In the Stream Management Table, select Data Streams from the dropdown in the top-right corner.
Locate the channel of interest and check the Sample Interval column to view the current interval (displayed in minutes).
Setting a Sampling Interval
In the Stream Management Table, hover over the channel whose sampling interval you want to change.
Identify which Sample Group the sensor belongs to.
Scroll down to Advanced Device Configuration below the Stream Management Table.
In the Sample Group folder, locate the corresponding group number.
Inside the relevant group folder, find the parameter named
group_sample_interval_sec.Modify the sample interval value (in seconds).
Click Submit to save the modified value. The change will be sent to the Wavelet as a command.
The Wavelet will receive the new sampling interval during the next data transmission.
Save your changes.
Note: Changes will only take effect after the device’s next transmission to the server.
