Ontoto Weather Station
Feature Description

Using this data logger, you will be able to monitor and manage your EMS once the installation has been completed. With simplicity in mind there is only one toggle switch and one SMA aerial connection.

  • 3G, 4G, LTE and BLE connectivity.
  • Sensor data stored in flash memory on board as a backup.
  • Network synchronised utilising universal co-ordinate time (UTC) for all data points.
  • User customisable with site set up tools via Android app.
  • Strong and durable casing to protect the internal hardware.
  • The standard aerial is vandal resistant.

The Ontoto EMS has been designed to comply to Australian Standards:

  • AS/NZS 3820:2009 for low voltage battery powered devices.
