Theory of Operation
The
NexusGEO
is a Bluetooth interface between a range of sensors and an Android
device. The raw signal output from the sensor is transferred from the
NexusGEO
to the
Android device via the
NexusGEO
app and the values displayed on the Android device
where they can be converted into Engineering units, stored on the device and transferred
via FTP or email.
1.3 Software
The
NexusGEO
mobile application (app) allows the user to configure the device with a wide
range of sensor types and download the data. It is available as a free download on the
Google Play Store.
As part of continual improvement, updates to the software may occur and should be
downloaded to ensure the current version is being used. Please visit the Google Play Store
to check for the latest version.
1.4 Host System Requirements
•
Android device with Android OS Version 8 or higher (Minimum SDK Version 19) and
Bluetooth
•
In order to use FTP functionality, a FTP server will be required.
1.5 EMC –
Electro Magnetic Compatibility
EMC is the electromagnetic interaction of electrical and electronic equipment with other
electrical and electronic equipment. All electronic devices have the potential to emit and be
affected by electromagnetic fields. With the reduction in size of electrical components and
the ever increasing amount of electrical & electronic devices such as mobile phones, two
-
way radios, safety control systems, signalling, generators, welding equipment, power cables
etc in all environments, especially construction sites, there is a huge potential for devices to
interfere with each other.
The
NexusGEO
has been designed and tested for EMC under the relevant CE marking
directives to ensure compliance and reliable operation
