Gather sensor data in seconds

Every sensor you need, on one tiny board

Attach the boards to the body, to animals or to objects to gather sensor data.

Accelerometer

Measures acceleration.
Gyroscope

Measures angular velocity.
Magnetometer

Measures magnetic forces, generally used for orientation and as a compass.
Sensor fusion

Quaternions and Euler angles from the Bosch sensor fusion Kalman filter.
Pressure

Measures atmospheric pressure for weather forecasting and altitude.
Temperature

Measures the ambient temperature.
Light

Measures luminosity.

Stream or log

Log data for days, or stream instantly

Stream sensor data live to your smartphone or leave the sensor to record into its own memory for days on end, and download the data when you are ready.

Live streaming over Bluetooth Low Energy
On-board logging up to 100M data entries
Synchronized timestamps on every sample
