Wireless 3-Axis Acceleration/Altimeter - PS-3223

Wireless 3-Axis Acceleration/Altimeter


The Wireless 3-Axis Acceleration/Altimeter measuring acceleration in all three dimensions as well as altitude making in useful for a wide variety of activities and experiments.

The 3-Axis Acceleration/Altimeter includes a strap so that students can collect data during any number of physical activities without cables getting in the way. The sensor is surrounded by a rubberized case that protects it from impact. The 3-Axis Acceleration/Altimeter can also remotely log acceleration and altitude data, making it ideal for recording the motion of roller coasters or other rides.

Typical Applications:

  • Launch or toss the sensor to record data during its flight
  • Record the movement of amusement park rides such as roller coasters, tilt-a-whirls, free-fall drops and more
  • Investigate the accelerations experienced during collisions
  • Measure the angular velocity of a rotating platform or wheel

No need for an interface.

All PASCO Wireless Sensors connect to computers, Chromebooks, and tablets, through Bluetooth 4. No other equipment required! Our software (SPARKvue or PASCO Capstone) allows students to see and analyze data in real time.

Long lasting battery

The Wireless Acceleration/Altimeter draws as little current as possible. This provides you with long battery life for lab activities. Our software also displays the battery level at all times. If it dips too low, you can easily replace the coin cell battery.

Bluetooth Low Energy Wireless Connectivity

Required Software:

PASCO products that use Bluetooth® Low Energy connectivity (wireless sensors, Smart Carts, and the AirLink) require the latest versions of our software.

PASCO Capstone is available for Mac and Windows. SPARKvue is available for Mac, Windows, iOS, Android and Chromebooks.

Additionally, the Wireless Motion Sensor and Wireless Smart Carts can be connected via Bluetooth and used with our MatchGraph app.

Compatibility/System Requirements

Any current model Chromebook, Mac, iPad, iPhone, Android tablet or phone will support direct connection to PASCO Bluetooth Low Energy devices. Also, any Windows 10 device with Creators Edition 1703 or later will support direct connection.

Chromebook users MUST have the latest firmware updates for ALL wireless sensors in order to use them without the USB Bluetooth Adapter. Full information.

All other Windows computers/tablets, older Macs, and Chromebooks without updated sensor firmware currently require the PS‑3500 USB Bluetooth Adapter to connect to PASCO’s Bluetooth Low Energy devices.

Full compatibility details are available, including compatibility information for older computing devices.


Independent datalogging 

Long term data collection directly on the sensor

In logging mode wireless sensors collect data to their onboard memory for hours, days, weeks or even months at a time without needing to be connected to a computer, tablet, Chromebook or smartphone.

When the experiment is concluded, simply connect the sensor to a device running PASCO software and download all the measurements it recorded.

Buying Guide

USB Bluetooth Adapter

Windows devices, Chromebooks and older Macs lack native Bluetooth® Smart support and require an adapter to use PASCO wireless products.

All current model Macs, iPads, iPhones, Android tablets or phones support direct connection to PASCO Bluetooth Smart devices and do not require the adapter.

Full compatibility details are available.
