RAKwireless RAK2560 WisNode Sensor Hub is a modular sensor gateway based on the RAK4630 WisDuo Stamp module with Nordic Semi nRF52840 Bluetooth 5.0 LE MCU and Semtech SX1262 LoRa/LoRaWAN transceiver and equipped with two sensor probe ports to connect a range of sensors.
It ships with various sensors from a temperature and humidity sensor to a water level sensor, and is designed for outdoor operation with an IP66 design, waterproof probe connectors, and the ability to support a solar panel as the power source.
RAK2560 WisNode Sensor Hub specifications:

RAKwireless provides documentation with a getting started guide and datasheets for the Sensor Hub and sensor probes.
I first found the RAK2560 WisNode Sensor Hub on Aliexpress where it is sold as part of kits for $99.00 to $393.00 depending on the selected probe, but you’ll also find those directly on the RAKwireless online store.
