Single Channel Node

Our Single Channel Node is a wireless data logger that makes geotechnical probes suited for LoRaWAN wireless communication. Each node supports one geotechnical probe, and can accommodate an extra NTC thermistor. The Single Channel Node can be configured on our Move Cloud Platform: you can set different parameters remotely and monitor the data collected at any time. This new Node comes with increased battery life, a wider range of supported probes and a new accelerometer-triggered acquisition mode.

8 models for the widest possible compatibility

The Single Channel Node is available in 8 models, each one suited for a different kind of probe interface. Refer to this chart to choose the correct models for your needs.

Applications

Geo-environmental Monitoring

Analyzing the displacement of the ground (settlement or lateral movement) and the stress-deformation state of the ground with inclinometer probes and vibrating ropes. You can also monitor all external atmospheric agents such as wind direction and speed, rain, humidity and temperature.

Hydrogeological Monitoring

With sensors such as piezometers, it is possible to monitor the level of groundwater and surface water and correlate it to the soil subsidence values.

Structural Monitoring

The use of crack meters allows you to keep a dangerous crack pattern under control. You can also monitor the stress-strain state of the structural elements using strain gages and correlating the data with the temperature.

Geotechnical Monitoring

By inserting load and pressure cells into the ground, it is possible to monitor both the pressures exerted by the ground and the distribution of loads on the foundations and their deformations.

Easy installation of the Move wireless monitoring system
The installation of an entire wireless sensor system on site is quick and easy: simply mount each device with at least two screws on the structure you want to monitor and power the LoRaWAN Gateway. You can configure the entire system remotely, before, during or after installation, using your laptop or tablet. After assembly and setup, the Move wireless monitoring system will start measuring and you can start monitoring remotely.

 

Operation of the Move wireless monitoring system
The wireless sensor system automatically communicates the measurement data via LoRaWAN with the on-site Gateway which in turn sends the received data via 4G or LTE to the online servers. The Move Cloud Platform is the cloud-based web tool that allows you to access, view and export your measurement data and configure the settings of the entire sensor system. You can access the Move Cloud Platform 24/7 from any location or device around the world. One of the main advantages of the Move Cloud Platform is that it offers remote access to measurement data and allows remote configuration of all installed sensors. This saves time and labor. In addition, you can analyze the measurement data using processing algorithms included in the service. Perform complex calculations, correlations and analyzes automatically and effortlessly. With the touch of a button, you can export measurement data in CSV format. You can also easily configure alerts to multiple recipients who will receive threshold cross notifications via email.

  • Easily install the entire system on the structure without the use of wiring.
  • Configure all wireless sensors quickly and remotely.
  • View real-time measurement data wherever you are, on any device, 24/7.
  • Process the data collected through the implemented algorithms.
  • Constantly monitors the operating status and signal quality of the system remotely.
  • Customize your alarm notifications and receive overrun notifications by email.
  • Optionally, you can integrate data on your platform using an MQTT bridge, FTP or through API calls.
