Detects motion and stillness states, as well as falls and tipping of people and objects.BraveJIG Accelerometer Module
- Model Number
- BJ-MD-S3-01
- Product Category
- Sensor Module
Detects motion and stillness states, as well as falls and tipping of people and objects.
With a sampling frequency of up to 5 Hz, it enables reliable monitoring for applications such as fall detection, motion analysis, and activity recognition.
Note: Future models will support higher sampling rates, expanding usage to machine vibration monitoring and predictive maintenance applications.
The module connects to the router using Bluetooth® technology.
The module communicates with the router via Bluetooth® Low Energy. Communication of several hundred meters is also possible in Bluetooth® Long Range mode.
Various power supply options available depending on site conditions
Power supply to modules can be selected according to installation conditions and sensing frequency. Options include power from the router via module cable, from a BraveJIG Battery, from a distribution board or AC power source via an external power conversion adapter, or from a mobile battery using a Module USB Type-A conversion cable.
