Geosense Wi-SOS 480 LoRa Wireless Sensor Observation System

Geosense Wi-SOS 480 (Wireless Sensor Observation System) er et LoRa-basert system for å fjernlogge og overføre signaler fra en sensor med en vibrating wire, volt, 4-20 mA, SDI-12 eller resistansutgang over lange avstander på opptil 15 km.

  • Brukeren kan konfigurere og laste ned data med en mobiltelefon med Android teknologi
  • LoRa-radioteknologi opererer på 868 MHz frekvens og overfører data opptil 15 km
  • Ekstra kraftig batteri med opptil 10 års levetid


The Wi-SOS 480 (Wireless Sensor Observation System) provides a system to remotely log, transmit and receive data signals from any sensor with a vibrating wire, voltage, 4-20 mA, SDI-12 or resistance output over long ranges up to 15 km.

Stand-alone Wireless Tilt Meters are also available which can be integrated into the system, together with any type of Node. The user can configure, diagnose, and download from a mobile device using android technology.

The Wi-SOS 480 is a star network consisting of a series of wireless nodes and a gateway. The gateway collects the data from the long-range star network, stores it locally and it is available to view and/or download via GPRS, wired Ethernet or Wi-Fi. No system planning is required and repeaters are not required, saving on installation costs.

What makes Wi-SOS 480 different to other wireless systems is the use of data modulation via the Worldsensing G6 Platform which uses the latest LoRa spread spectrum technology. This technology means long range, low cost, low power consumption and high connectivity.

Software is embedded in the gateway which allows it to be fully configurable over air or Ethernet and a fast mode allows full diagnostics to ensure correct operation of the system.

The Wi-SOS 480 Web Centre provides a platform to view and download data plus upload images for each project and view on PC, tablet or mobile phone; or the data can be forwarded to any FTP for inputting into most visualization software.

The Wi-SOS 480 offers a highly flexible and cost-effective solution for projects where a cabled solution is not possible due to physical barriers and/or access restrictions and where real-time monitoring is required.
