ProMove-V is Inertia’s new-generation waterproof and dustproof wireless Inertial Measurement Unit (IMU). Using Inertia’s high-speed and low-power wireless technology, a network of tens of ProMove-V’s can sample and stream all sensor data at high data rates within 100 ns synchronization accuracy across all devices.
ProMove-V features a complete set of ultra-low-noise digital sensors, offering multi-modal and multi-DoF (degrees of freedom) sensor data:
- 3-D low-range acceleration
- 3-D high-g acceleration
- 3-D turn rate / gyroscope
- 3-D magnetic field intensity / compass
- Barometric pressure (optional)
- GNSS (optional) for localization and tracking
The sensor data is transmitted wirelessly to a central node, the Inertia Gateway, which connects to the computer through USB and acts as the master hub for data collection and sensor configuration over-the-air. The Advanced version of the Inertia Gateway provides additional features such as synchronized trigger and clock for external systems, as well as Raw Ethernet data transfer support.
The number of devices in the network scales with the sampling rates: for example, a network can have 39 nodes operating (sampling and communicating) at 200 Hz, or 19 nodes operating at 500 Hz.
ProMove-V is also equipped with 16 GB of internal storage. All sensor samples are logged internally, in addition to being sent over-the-air. Any information lost during the wireless transmission can be recovered at the end of each measurement round.
The Inertia Studio software (freely available on our website) is the interface for visualizing the incoming data in real-time and configuring all devices in the network and all sensors. Full access to the raw sensor data is provided to the user, as well as 3-D orientation information, expressed as quaternions and Euler angles. C++, Java and Android SDKs, along with examples, are also available for integration with custom applications.
ProMove-V is carefully designed for good ergonomics. The curved design makes mounting and wearing on body parts comfortable, without affecting stability in case of surface mounting. Hook and loop straps of 40 cm in length are provided as part of the ProMove‐V sensor package. They can be attached through the handles of the sensor nodes for mounting on body parts or clothing, such as wrist, ankle or shoe.
A set of maximum ten ProMove‐V sensor nodes can be charged by using the ProMove‐V charging cradle.
ProMove-V sensor nodes can be purchased separately or as part of a complete package, as described in the configurations section.
