Valid residence time: The residence time exceeds the specified time, which is 4 seconds by default in the javascript sdk (parameters can be set). The javascript sdk sends a page stay event if a page scroll occurs and the previous page stay is valid, that is, longer than the default 4 seconds or a custom time.	This event needs to be captured in order to use the thermal map-reachability diagram function of the Sensors Analytics.

(3) The latest paid advertising related parameters are event attributes and do not need to be configured. They will exist in all events. This attribute will save the most recent valid utm_source.

3. Preset properties related to UserAgent

These properties are parsed from the UserAgent of the browser.

Field Name	Type	Description	SDK Version
$manufacturer	String	Device Manufacturer	v1.6 and above support new parsing method
$model	string	device model
$os	string	operating system
$os_version	string	operating system version
$browser	string	browser name

$bot_name	String	Spider Name

Currently, it is determined by UA and has a default property $bot_name (Spider Name). However, there are two situations that cannot be determined:
Firstly, if the UA does not indicate and the illegal spider triggers JS scripts.
Secondly, if the spider does not trigger JS scripts, it will not trigger our SDK, so it won't be counted in the statistics.
For spider types, the parsing of mainstream spider names is already supported. However, for newly added or other niche types of spiders, there may be cases where they cannot be parsed.

4. Preset User Properties

If the association between the login ID and the anonymous ID fails, the login ID will not have these property values.
$utm_source	String	First Campaign Source	Use Web Channel Track and collect these user attributes only when new users visit for the first time through the channel with utm parameters.
