RAK2560 WisNode Sensor Probe Datasheet
Overview
Description
The Sensor Probe is an accessory for the Sensor Hub solution platform. It supports up to two WisBlock sensors in various combinations to provide the needed data.
The Sensor Probe could not be used as a standalone product. You need the RAK2560 WisNode Sensor Hub in order to use this probe.
Product Features
- Auto-identification of the sensor type
- One-wire protocol
- Waterproof (IP67-rated)
- Supports up to two (2) WisBlock sensor modules
Specifications
Overview
Dimensions
The Sensor Probe dimensions are 90 x 30 mm. The body has a cylindrical shape. There is one physical port for connection to the Sensor Hub with a 100 cm cable length. The Sensor Probe is IP67-rated, suitable for outdoor use, with GORE venting. The device is designed to meet the UL/EN60950-22 standard.

Due to RAK1901 and RAK1902 having temperature sensor with different accuracy levels, you will get two temperature values in the WisToolBox app.
Sensor Connection Diagram
The RAK2560 can support both Sensor Probes and Probe IO in all possible combinations.
If you want to add a Probe IO to your setup, the Sensor Hub must be supplied by an external 12 VDC power source.
