TWTG NEON

NEON Product Introduction
NEON stands for a standardised approach to collecting data points from the operational environment and in doing so, creates a general approach to integrated solutions within existing IT ecosystems.
The TWTG NEON product range supports all industrial customers moving towards LoRaWAN as the Industrial IoT network of the future.
The LoRaWAN network gives industrial operations a secure solution, which scales-up to tens of thousands of sensors, covers complete sites with only a small amount of gateways and best of all – the low-power approach means that the lifetime of the NEON products can be extended dramatically.

  • measurement_interval_seconds
    Interval in seconds, at which the vibration sensor is read.
  • periodic_event_message_interval
    Interval in the number of measurements at which the application event messages are periodically sent. The periodic counter is reset on every event message.
• Condition
  A condition-based trigger can be either of the following tresholds:
  • rms velocity trigger_x
  • peak acceleration trigger_x
  • rms velocity trigger_y
  • peak acceleration trigger_y
  • rms velocity trigger_z
  • peak acceleration trigger_z
