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: Sensor Hub with Senor Probe can work with 2 to 4 batteries only. To use the Probe IO with Sensor Hub you need to power it with the designated power adapter. The power adapter can be selected from the check to include section.
