Wireless Current Sensor - PS-3212

PS3212_MAIN.jpg

Overview

Measure currents of up to 1 A with built-in protection for the sensor against overload and transmit the collected data wirelessly to your computers, Chromebooks, tablets or smart phones.

The wide current range allows for introductory and advanced explorations of the fundamental concepts of electricity and basic circuits. Combine with the Wireless Voltage Sensor to explore Ohm's Law, series & parallel circuits and much more.

Note: the Wireless Voltage Sensor can be used with standard leads or patch cables but does not include leads. The leads that come with the Wireless Voltage Sensor can be purchased separately. See the buying guide below for details.

Since current can only exist in a complete circuit, the Wireless Current Sensor must be part of that circuit in order to measure current. It is connected in series and has a very low resistance (0.1 Ω). For this reason we don't don't recommend connecting it directly across a battery or other voltage source without a resistive load.

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 - Log current data directly onto 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 1.9.1 is available for Mac and Windows. SPARKvue 2.7.0 is available for Mac, Windows, iOS, Android and Chromebooks.

Compatibility/System requirements

Any current model Mac, iPad, iPhone, Android tablet or Android phone will support direct connection to PASCO Bluetooth 4 devices.

Windows computers/tablets, Chromebooks and older Macs 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.

Datalogging

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.

    USB Bluetooth Adapter
    1
    Required

    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.
