Included equipment

Air quality sensors

  • Nondispersive infrared sensor (NDIR)
  • E-ink display screen to show the sensor values on the actual unit itself
  • LED traffic light function
  • Buzzer alarm function
  • Wall mounted

LTE and LoRaWAN internet gateways

Spook recommended gateways come with ethernet and cellular connectivity as standard.

Gateways reside in appropriate locations around the building - dictated by the spread of sensors.

Sensor data is transmitted over the ethernet network with a cellular backhaul and is encrypted end to end and is sent to Spook's OmniWatch servers.

Gateways can be set to cellular operation as priority, ensuring monitoring is independent of the corporate network.
