RAK Wireless 3 Axis Acceleration Sensor

overview

The RAK1904 is a WisBlock sensor that adds an accelerometer to the WisBlock system. A ready-to-use software library and a tutorial make it easy to build a motion data acquisition system.

The RAK1904's scale of ±2g to ±16g can be adjusted to meet the requirements of your application. Depending on the application, the data rate can be set from 1Hz to 5.3kHz.

The RAK1904 combined with the RAK4631 WisBlock Core is a ready-to-use system for a motion tracking system, for detecting and monitoring vibrations in rotating machinery or even for monitoring active volcanoes. The collected 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. In addition, the WisBlock system allows the module to be switched off completely to further reduce the system's power consumption.

The RAK1904 accelerometer can be connected to other WisBlock sensors, such as a GPS module, to create an inertial navigation system.
