Remotely detect presence and movement wherever you may be with the NB-IoT occupancy sensor from Efento. Ideal for a wide range of use cases this smart device can be used to:

  • Monitor presence in empty buildings
  • Detect unauthorised entry into restricted areas
  • View room oppupancy levels in shared areas
  • Assess footfall in certain areas to build up a better picture of busy entrances/exits

Based upon the data recorded by the NB-IoT occupancy sensor users can gain valuable insights into how different spaces are utilised.

Using NB-IoT (Narrowband IoT), this sensor uses cellular networks to transmit recorded data. NB-IoT sensors can be integrated with any cloud platform and are easily connected by a cellular IoT SIM card. Simply insert your NB-IoT SIM card and away you go.
