Data Transmission

Data transmission by type of Datalogger

Xsense works with a variety of dataloggers suited to different requirements.  A key difference between types of dataloggers is the means by which data is retrieved from the dataloggers.

  • Data on Xsense® HiTag™  dataloggers can be read by Xsense® wireless gateways (aka CUs).  The gateways relay the data collected from the tags to Xsense® Cloud.
  • Data on Xsense®-compatible all-in-one cellular real-time dataloggers is automatically transferred to the Xsense® Cloud whenever the dataloggers are connected to the cellular network.
  • Data on select USB dataloggers may be exported to one’s computer and then be uploaded to Xsense® Cloud via the Xsense® web portal.

 

Details about Xsense® Wireless Gateways

HiTag™ dataloggers are typically used in conjunction with the Xsense® wireless gateway.  The gateway will read data from the dataloggers, and will pass it to Xsense® Cloud.

The operation of getting data from the datalogger to the gateway begins with the gateway announcing its presence. When the HiTag™ hears the gateway, it will attempt to synchronize with the gateway.  If successful, the HiTag™ will pass data to the gateway.  These steps happen automatically.

The gateway will store the data of the HiTag™ in a buffer, if it is not connected to the internet.  When it is connected to the internet, it will send the data in encrypted format to Xsense® Cloud.

The Xsense® wireless gateway (CU2) comes in several versions.

  • LAN Ethernet connectivity,
  • Cellular only (2G or 3G) connectivity, and
  • Dual  LAN and cellular (2G or 3G) connectivity.

The cellular option affords speedy installation will keeping the gateways separated from corporate internal networks.

Xsense® Wireless Gateways (CU2) Specification

Gateways are provided individually or combined with accessory kits for specific applications.  Kits:

  • Gateway only
  • Gateway and kit for fixed installations,
  • Gateway and kit for fixed installations with dual RF antenna,
  • Gateway and kit for portable carry-on use, and
  • Gateway and accessories for mounting on a vehicle,

The gateway contains a large internal battery to ensure continued operation while being carried about, during a power outage, or when the power supply drops, such as in the evening when powered by a solar panel.

A GPS antenna is available as an option for tracking the location of the unit.

Details about Xsense® cellular all-in-one real-time Dataloggers

Xsense® cellular real-time dataloggers take care of transmitting data to Xsense® Cloud all by themselves.  They contain SIM cards and will attempt to connect to one of the local cellular carriers.

The cellular real-time dataloggers may not connect to the cellular network, if:

  • The country is not covered by the carrier agreements of the SIM card provider,
  • The local carrier is not supported by the SIM card provider,
  • The real-time datalogger does not support the technology (i.e. 2G versus 4G) of the local carrier network.

While not connected to the cellular network, the real-time dataloggers will store readings in their memory.
If cellular connectivity is not possible, it is possible to transfer data via USB connection with a USB adapter cable with specific models
