Editorial narrative

The Sensor Hub environmental monitoring and moving detection solution includes a combination of the popular RAK1901 Temperature and Humidity Sensor and the RAK1904 3-axis Acceleration Sensor inside the Sensor Probe. Their low power consumption and accurate data-gathering abilities allow you to catch even the slightest changes in your environment, including movement. 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. An example of that can be found in the supply chain industry, Smart cities, and even industrial settings. The 3-axis accelerometer can double as an anti-theft measure for your environmental monitoring 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. Features 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) Parameter Value Temperature accuracy ±2.0 °C Temperature range -40 to +125 °C Humidity accuracy ±2.0 % RH Humidity range 0 to 100% User-selectable scales ±2g/±4g/±8g/±16g Data acquisition rate 1 Hz to 5.3 kHz Included in the Package: 1x Sensor Hub 1x Sensor Probe TH3X
