The health of a module refers to the lifespan of the module. Hours of usage,
and the pollutant concentrations during this usage are recorded by each mod-
ule, and used to calculate lifespan, and current health levels.
When the health of a sensor drops below 10%, the potential for drift in
accuracy or module failure increases, and it is necessary to change the sensor
module. For instructions, see the “Introduction to Sensedge” in this booklet.
Note: when a sensor is inserted, it may take several seconds to appear on this
view.
Data Export
Used to export historical data contained within the device or in the cloud.
Three methods of data export are supported: e-mail, USB and SD card.
E-mail Export:
Used to send readings directly from the cloud to your e-mail.
This is an easy way to receive historical air quality readings on your computer
for analysis. Files are exported in .csv format, and can be directly opened in
Microsoft Excel and other spreadsheet software. Data export via e-mail will
only transfer readings that are stored in the cloud, and not readings that are
stored locally on the device and unavailable in the cloud. If the Sensedge is
connected to the Internet most of the time, this is the recommended method
of data export.
USB & SD Card Export:
Used to export readings stored locally on the
Sensedge to a USB device or SD card inserted into the Sensedge. Historical
readings are exported in .csv format. Data export via USB and SD card will only
transfer readings that are stored on the device, and not readings in the cloud.
If the Sensedge is primarily used offline, this is the preferred method for data
export.
Wi-Fi
The Sensedge supports 2.4G Wi-Fi connectivity, which can be enabled in the
Wi-Fi settings view. Simply select the Wi-Fi network by tapping once, and
enter the password by tapping on the password input.
The Sensedge will store previous Wi-Fi connections and connect automatically
to a network, if available. To remove, or “forget” a Wi-Fi network, simply tap
the “Forget” button next to the network name.
