The Sensor Hub environmental and atmospheric monitoring solution includes a combination of the popular RAK1901 Temperature and Humidity Sensor and the RAK1902 Barometer Pressure Sensor inside the Sensor Probe. Their low power consumption and accurate data-gathering abilities allow you to create a reliable weather station or a comprehensive environmental monitoring system.

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 temperature, humidity, and atmospheric pressure are important, like in the food industry for guaranteeing the perfect preservation conditions, agriculture, and industrial applications. Sewage systems and many more can also benefit from the solution.

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.
