The solution delivered by the Softeq IIoT development team features a Carrier Vibration Sensor (CveVT5) equipped with low-power, three-axis accelerometers, which have 12-bit resolution. Their high bandwidth and high sensitivity characteristics allow end-users to capture highly accurate data and predict the wear of machine parts and tools.
The CveVT5 device operates in one of three modes:
- Sleep (i.e., energy-saving mode)
- Advertising
- Connected
As long-term functioning was one of the client’s key requirements, our engineers managed to achieve a 12-month battery life in the Sleep mode with occasional activity, and one-month non-stop functioning.
Sensor-to-device data transfer is based on the BLE communication standard. The communication protocol has been specified and customized by the Softeq team.
The captured measurements are transferred to a host device via the BLE interface. For the device hardware part, our engineers chose ConnectBlue’s OLP425 evaluation board, which natively supports low-energy BLE connectivity.
For a full-scale demonstration of the API’s capabilities, we developed a sample iOS app.
The project has been delivered with the key solution parameters:
- Sampling Speed — 110%
- High data buffering capacity — 100% (all RAM on CPU)
- Long battery life — 100%
