PhidgetSpatial Precision 3/3/3

The PhidgetSpatial Precision 3/3/3 combines the functionality of a 3-axis compass, a 3-axis gyroscope, and a 3-axis accelerometer all in one convenient package. You can use the Spatial channel to use all three sensors with the AHRS or IMU algorithms to get motion data in quaternions for accurate spatial tracking. Or, you can use the data from each of these sensors separately to measure tilt, vibration or rotation of an object.

This PhidgetSpatial also features a temperature stabilization circuit to warm the sensors to a constant 50°C to minimize temperature effects.

Features:

• 3-axis accelerometer (±16g)
• 3-axis gyroscope (±2000°/s)
• 3-axis magnetometer (±8G)
• Accurate timestamp for plotting or advanced calculations
• Built-in support for AHRS and IMU algorithms
• Built-in heater for temperture stabilization up to 50°C
• Versatile connection via USB or VINT

Spatial Guide

Phidget Spatials combine data from accelerometers, magneometers, and gyroscopes into one sensor. This guide explains how the sensors are combined using AHRS, what you can do with this data.

Product Specifications

* - Minimum data interval depends on connection mode (VINT/USB) and on VINT mode, varies depending on how many of the device's channels are open simultaneously. See the Minimum Data Interval section below for details.

Minimum Data Interval

In order to determine the minimum data interval for a channel:

• In USB mode, the minimum data interval for each channel is equal to the "True Min" row in the table below, regardless of how many of the devices channels are open simultaneously.
• In VINT mode, the minimum data interval for a channel varies depending on your VINT speed and is equal to the sum of the numbers in each column, plus 1 for each open channel beyond the first. If the resulting number is lower than the "True Min" for that channel, the minimum data interval is equal to the true min. The VINT speed for the HUB0000 and HUB5000 is locked at 100kbps, while the HUB0001 can be adjusted as high as 1000kbps (see the HUB0001 User Guide for more details).

For example, if you have the accelerometer, magnetometer and temperature sensor open on VINT mode, running at 160kbps, that works out to 2 + 2 + 1, plus another 2 because three channels are open. The result is 7ms, so the minimum data interval for the accelerometer is 7ms in this scenario. It would be the minimum for the magnetometer and temperature sensor too, but their true minimum is both 10ms, so they will still have a minimum of 10ms.

Maximum Cable Length

Maximum cable length depends on two major factors: cable gauge, and communication protocol.

Cable Gauge

Thicker cables can carry power further, resulting in a greater maximum cable length. Using the self-heating feature of the MOT0110 consumes significantly more power, so this reduces the maximum cable length. The Phidget cables we sell are 26AWG and most USB cables are 24 AWG on the power and ground wires. Use the first table below to find the maximum imposed by your power setup.

Communication Protocol

The maximum cable length in USB mode is always 5m. The maximum recommended Phidget cable length in VINT mode depends on a few different factors. If the VINT port the MOT0110 is plugged into has a  icon printed on the enclosure, it means it's equipped with an improved filter which will increase the maximum cable length. The VINT speed you've selected will also impact maximum Phidget cable length (Only ports labeled with the  icon can set VINT speed, otherwise the speed is fixed at the 100kbps default). Use the second table below to find the maximum imposed by your communication protocol.

The lesser of the two numbers from these tables is your maximum cable length.

Protocol / VINT Speed	Cable Length (m)
USB	5
100 kbps (no )	5
100 kbps (with )	50
160 kbps (with )	35
250 kbps (with )	20
400 kbps (with )	11
500 kbps (with )	8
800 kbps (with )	4
1000 kbps (with )	2.5
