<p>Updating to match new version of source page</p> <p><b>New page</b></p><div>&lt;languages/&gt;<br /> == Data formats ==<br /> <br /> Within the AMBIsense solution, measurements of the 1/3-octave band spectrum are performed. The results of these measurements can be exported in multiple formats:<br /> <br /> * as a self-explanatory CSV table;<br /> * as one of the following very simple, yet efficient proprietary binary formats:<br /> ** a phen1 file: a very restrictive format that keeps small datasets as small as possible, while maintaining random access on row level;<br /> ** an [[ASAsense Binary Table (ABT) format/en|ABT]] file: a binary table format with fast and efficient random access (both on row and column level).<br /> <br /> == Instant measurements ==<br /> <br /> The AMBIsense sensors can be configured to send instant measurements to a dedicated MQTT broker. These have the following structure:<br /> <br /> * audio measurements (8 messages / s):<br /> ** topic: &lt;code&gt;/instant/&lt;deviceName&gt;/measurements&lt;/code&gt;<br /> ** payload, in msgpack:<br /> *** timestamp: float<br /> *** dBA: float (sound level)<br /> * classifications (frequency depends on the model):<br /> ** topic: &lt;code&gt;/instant/&lt;deviceName&gt;/classification/&lt;modelId&gt;/&lt;modelVersion&gt;&lt;/code&gt;<br /> ** payload, in msgpack:<br /> *** timestamp: float<br /> *** confidences: float[] for each class</div>
