Wireless Voltage Sensor - PS-3211



Ideal for exploring the fundamental concepts of electricity and exploring circuit concepts.   Measure voltages of up to 15 V with built-in protection for the sensor against overload. 

Combine with the Wireless Current Sensor for explorations of Ohm's Law, series and parallel circuits and much more.

The Wireless Voltage Sensor includes shrouded-banana to alligator-clip test leads,one red and one black

Special Features

  • Simplicity: just pair and go, no cables and adapters to manage
  • Variable sampling rate for capturing small fast changes or experiments that run for hours, days, or weeks.
  • High speed sampling available via USB connection in "burst mode"
  • Long-lasting rechargeable battery.
  • Logging mode - collect data directly on the sensor for long term experiments.

Bluetooth 4 Connectivity

Required Software:

PASCO products that use Bluetooth® 4 technology - wireless sensors, smart carts, and the AirLink Interface - 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 Android phone will support direct connection to PASCO Bluetooth 4 devices. Also, any Windows 10 device w/ 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 Chromebook users without updated sensor firmware currently require the PS-3500 USB Bluetooth 4.0 Adapter to connect to PASCO’s Bluetooth 4 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.
