RAK1904:WisBlock 3-Axis Acceleration Sensor

RAK1904 is a WisBlock sensor that extends the WisBlock system with an acceleration sensor. A ready-to-use software library and tutorial make it simple to implement a motion data acquisition system. The RAK1904's scale from ±2g to ±16g can be adjusted according to your application's requirements. Depending on the application, data frequencies can be adjusted from 1Hz to 5.3kHz.

The RAK1904 combined with the RAK4631 WisBlock Core forms a ready-to-use system for a motion tracking system, to detect and monitor vibrations in rotating machinery, or even to monitor active volcanoes. Acquired data can be sent via LoRaWan® communication, LoRa® point-to-point connections, and BLE. The RAK1904 is ideal for battery-powered applications due to its low power consumption. Additionally, the WisBlock system allows the module to be completely powered off to further reduce system power consumption. The RAK1904 acceleration sensor can be combined with other WisBlock sensors, such as a GPS module, to create an inertial navigation system.
