# Atmospheric pressure ## Oversampling settings At each measurement, the device can take a few samples and calculate the average value in order to increase the measurement accuracy. This allows to reduce the noise but decreases the battery life time. Users can decide how many samples should be taken at each measurement and how the samples should be proceeded. It is possible to select one of the six oversampling options: disabled (one sample per measurement) 2, 4, 8, 16, 32. In order to change the oversampling, connect to the device, and from the settings menu select “Advanced” -> “Calibration” -> “Calibration parameters” -> “Select a channel” -> “Number of samples per measurement”. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.efento.io/nb-iot-loggers/sensor-specific-settings/atmospheric-pressure.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
