Editorial narrative

The Sensor Hub environmental monitoring solution includes the popular RAK1901 Temperature and Humidity Sensor inside the Sensor Probe. Its low power consumption and accurate data-gathering abilities allow you to create your own reliable environmental monitoring system with multiple sensing points and a centralized data hub. 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 and humidity are important, like in agriculture (especially in greenhouses and incubators), industrial settings (workshops and industrial units), or even smart cities, offices, and homes. 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.
