AX6
6-axis logging accelerometer
£199.00 – £209.00 exc VAT
AX6 is a data logger capable of recording raw data from a suite of integrated sensors. It features a state of the art 6-Axis movement sensor measuring linear acceleration and angular velocity at high precision. All sensor locations and orientations are identical to the AX3 for maximum compatibility. All data is stored in its raw unaltered formatt on the embedded flash memory. The device is ideal for collecting longitudinal movement data.

Technology
Microprocessor
It is the Microprocessor’s job is to talk to the host computer over USB, negotiate battery charging and to precisely keep the time. In simple terms, the microprocessor is the brain of the sensor.
Movement Sensor
This tiny component contains two closely coupled MEMs sensors, and accelerometer and a gyroscope. The accelerometer is used to detect linear acceleration (movement) and orientation changes. The gyroscope measures angular velocity (rotation). Both sensors have three high precision measurement axis. The sensors can be sampled at configurable rates and precision.
NAND Memory
This memory chip is used to store all the data the microprocessor pulls from the sensors. Each sample is stored along with a precise time- stamp; this allows for accurate signal reconstruction. The data stored on the NAND Memory is in raw format has error checking and correction (ECC) built in.
Lithium Battery
Content to be supplied by Axivity.
Light Sensor
The light sensor can be used to help determine periods of wear as well as provide useful environmental data.
Light Emitting Diode
The LED indicated what state the sensor is in; charging, standby, recording or communicating to a computer.
Temperature Sensor
The temperature sensor gives a sense of outside environment temperature and also if the sensor is being worn.
