MonStr Ecosystem
MonStr-Adaq
4- or 8-channel analogue-to-digital acquisition units for analogue sensors, installed in the field next to the sensors.
MonStr Panel
Electrical cabinet that connects, powers and manages sensor networks in the field, in three configurable versions.
MonStr Polaris
Portable station to acquire and analyse data in the field, with operational modal analysis (OMA).
MonStr-O
MonStr-O is the MonStr node designed for structural health monitoring. An IP68 aluminium box holds an extremely low-noise 3-axis accelerometer and a 2-axis inclinometer, both designed specifically for SHM, a 3-axis gyroscope and an internal thermometer.
A synchronization engine syncs the clocks of an unlimited number of devices on the network. A single connector carries both power supply and data, with plug and play functionality: connect one cable and the node starts working automatically.
Features
-
Remote access to the data
MonStr system for SHM gives you access to your data from anywhere via the web app.
-
Data provided
Data provided through hdf5 database.
-
Customizable device set-up
Sensor parameters for each device on the network can be customized by selecting the dynamic range, sample frequency, etc. The acquisition software automatically customizes all devices.
-
Extremely low power consumption
Each MonStr draws a mere 0.6W.
-
Independently configurable
Each node's sensors and features are independently configurable.

Advantages
Synchronized
Unlimited channels are synchronized with each other to a fraction of a millisecond, assuring the temporal coherence between all collected data.
Distributed
The sensors are designed to be installed in any condition, thanks to the use of a single ethernet cable for both power supply and data transport.
Scalable
MonStr Nodes can be easily added to or removed from the monitoring system, making the system fully extendable and scalable.
