Description

BoB Assistant is a LoRaWAN® low power compatible vibration sensor perfect for indoor and outdoor predictive maintenance of industrial applications. It is combined with a temperature sensor made for environmental conditions, an RGB Led for the User Interface and a push-button.

The sensor monitors the vibration signature of an equipment (pump, ventilation, etc.) on the ranges 0 to 400Hz (± 6Hz) and 0 to 12.4kHz (± 200Hz) every 5 minutes adjustable). After an automatic learning period of 7 days, the sensor alerts in case of vibration drift, allowing maintenance teams to intervene before a breakage or failure.

The data transmission on public or private LoRaWAN® network is done periodically or immediately in case of alert:

  • Exceeding the vibration drift threshold (adjustable).
  • Machine on/off (adjustable).

Installation and commissioning is quick and easy.
