Wireless Accelerometer
Move Solutions Accelerometer is a wireless sensor that measures acceleration and frequency on three axes. It can be synchronised with other Accelerometers for Modal Analysis and it detects seismic vibrations. The device can be set up and managed remotely via Move Solutions IoT Platform.
Move Solutions Accelerometer is an extremely precise three-axis wireless sensor, capable of synchronizing data samples with all the other Accelerometers in the system. Wireless synchronized sampling is a very important feature that gives many benefits during structural monitoring. Thanks to this feature it is possible to carry out the Modal and Vibrational Analysis of any type of structure. Sample rates are variable and remotely configurable. The Accelerometer also maintains the classic activation threshold operation. The battery-powered device has an operating autonomy of up to 8 years and it also has a temperature sensor.
The wireless Accelerometers transmit accurate readings from the site via the LoRaWAN wireless communication protocol via a gateway. You can view and interact with your data online using Move Solutions IoT Platform.
