Voltage Interface Node
The WiSenMeshWAN® system provides dynamic and autonomous wireless data acquisition from geotechnical sensors using state-of-the-art technology. The automated measurement of geotechnical sensors, using long-range wireless radio nodes and a SmartGateway, allows users to focus on more demanding tasks instead of manually acquiring and recording data.
WiSenMeshWAN® sensor nodes are transmitters and receivers that create a self-forming dynamic radio mesh network that sends data to a SmartGateway. Users have complete remote control of the system through direct, triggered or scheduled changes, enabling dynamic measurements and automated reporting.

The physical “Vcc_Out Hardware Switch” is used to:
Example: For model 6C01, Vcc_Out must be set to 2.5 V to power an EC-5 soil moisture sensor and allow the node to sample signals between 0 and 2.5 V. Warning: For other sensors, review their specifications before configuring the node. | |
| Vcc_Out output switch configuration | |
| Switch position | Output voltage (Vcc_Out) |
| 0 (default) | 1.8 V (default) |
| 1 | 2.5 V |
| 2 | 3.3 V |
| 3 | 5.0 V |
The sensors are plug-and-play and operate straight out of the box through a self-configuring radio network. Multiple interface options enable integration with third-party sensors from leading geotechnical manufacturers using analogue, digital and vibrating-wire interfaces.
Designed for up to 10 years of maintenance-free operation, the units have an IP65 or higher protection rating and feature internal power supplies and radios. Thanks to their robust industrial enclosures, they can be installed in multiple ways to meet the different requirements of monitoring projects.
