Wireless Voltage Sensor

Product Code: PS-3211


The Wireless Voltage Sensor is ideal for exploring the fundamental concepts of electricity, voltage, and basic circuits.  It measures voltages up to ±15 V with built-in overload protection and features high-speed sampling rates when used with a USB. When combined with the Wireless Current Sensor, students can use it to explore Ohm’s Law, circuits in series and parallel, and much more.


  • Two Ranges: ±15 V, ±5 V
  • Resolution: 7 mV (±15 V range); 2 mV (±5 V range)
  • Bluetooth® sampling rate of 1 kHz
  • Higher speed sampling via USB
  • Includes remote logging


  • Measure the electrical energy generated by an electrochemical battery
  • Measure the energy generated by a wind turbine or other renewable energy source
  • Measure the voltage across components in a simple circuit
  • Measure the induced voltage in a wire coil as a magnet passes through
