Track Sports Movement & Shock Vibration Instantly

Measures 3-dimensional motion (acceleration and angular displacement in 1, 2 or 3 axes), providing data for users to track sports activity or medical therapy compliance and improve performance.

The HOBO Pendant G Acceleration Data Logger is a waterproof, three-channel logger with 8-bit resolution and can record up to approximately 21,800 combined x-, y-, and z-axis acceleration readings or internal logger events. The logger uses a coupler and optical base station with USB interface for launching and data readout by a computer.

The logger can be used for a wide variety of experiments, demonstrations and field studies by measuring dynamic acceleration resulting from motion, shock, or vibration. It can also detect static acceleration of gravity, making it possible to measure tilt, activity, and inclination.

The logger uses an internal three-axis accelerometer with a range of ± 3 g based on micromachined silicon sensors consisting of beams that deflect with acceleration. These beams are arranged to act as a variable capacitor. As the beams move, the capacitance changes proportionately. This capacitance change is converted to voltage, filtered and measured by the logger, and displayed in the software in units of g-force.

Features

• Low-cost acceleration and tilt measurement
• Waterproof housing for wet or underwater use
• Data readout in less than 30 seconds via fast Optic USB interface

Important Information

Requires HOBOware software and either an Optic USB Base Station or a HOBO Waterproof Shuttle (U-DTW-1). HOBOware Pro is required when using the HOBO Waterproof Shuttle. See Related Products below.

HOBOware Software

HOBOware software is used for launching, reading out, and plotting data from HOBO® data loggers. With HOBOware, you can also check logger status, filter and export data, save changes to graphs in project files, and scale data with the Linear Scaling and Pulse Scaling data assistants. There are two versions of HOBOware: HOBOware and HOBOware Pro.
