The IMBuildings NB-IoT Comfort Sensor range offers a host of multi-sensor devices, designed to optimise your indoor environments. Whether you’re looking to enhance ambient temperature, monitor CO2 levels or detect presence, the IMBuildings NB-IoT Comfort range has you covered.

Available in a number of variants, with this smart device, you have the option to monitor:

  • Temperature & Humidity
  • Temperature, Humidity & Presence
  • Temperature, Humidity & CO2 (Economic or Professional)
  • Temperature, Humidity, Presence & CO2 (Economic or Professional)

The economic or professional variant options refer to the level of accuracy the sensor will provide. Economic models will provide an accuracy level of between +/- 50ppm + 5% of the reading. Whereas the Professional model will provide an accuracy level of between +/- 30ppm + 3% of the reading.

Ideal for use in areas where there may be a high number of people or where you want to optimise conditions, the IMBuildings NB-IoT Comfort sensor can be useful in:

With an easy to use app, users of this NB-IoT sensor are able to view up to 3 weeks worth of data history. Alerts can also be automated from the app to raise awareness when action is required or when data recoreded is outside of your selected threshold.

Utilising NB-IoT technology, this sensor is the ideal solution for maintaining optimal levels of ventilation. Simply insert your cellular NB-IoT SIM card to the sensor to get started.

Recorded data will be transmitted from the sensor by the connected NB-IoT network which is fulfilled by inserting a compatible SIM card. This data can then be decoded by our IoT middleware platform, Symbius.
