The Sensor Hub atmospheric monitoring and movement detection solution includes a combination of the popular RAK1902 Barometer Presure Sensor and the RAK1904 3-axis Acceleration Sensor inside the Sensor Probe. Their low power consumption and accurate data-gathering abilities allow you to create an atmospheric monitoring system that is also movement sensitive.

The Splitter cable can connect several Sensor Probes and Probe IOs to a single Sensor Hub port. The distance between the Sensor Hub and Sensor Probe/Probe IO can be extended via the Extension cable.

The product can be used in any use case where those parameters are of importance. For example in areas where atmospheric measurements are required but the strong wind may cause displacement of the equipment (weather stations in rough environments).

The 3-axis accelerometer can double as an anti-theft measure for your solution as well.

Note: The Sensor Hub can be powered with 2 to 4 ER18505 non-rechargeable batteries. They are NOT INCLUDED. You need to supply them separately. Find more on where you can find compatible batteries here.

The Sensor Hub has two variants based on the communication type - LoRaWAN® only and LoRaWAN®+NB IoT. SensorHub's NB-IoT module supports two types of LTE (Long-Term Evolution) categories, namely CAT M1 and CAT NB2. CAT M1 offers higher data rates and lower latency, while CAT NB2 provides ultra-low power consumption and greater coverage, making it an ideal choice for devices that operate on batteries and require long-term connectivity.


  • LoRaWAN®/NB-IoT communication
  • External DC power supply (optional)
  • Solar panel power source (optional)
  • Auto-identification of the sensor type
  • One-wire protocol
  • Waterproof (IP67-rated for the probe body)
