Wireless Voltage Sensor

The Wireless Voltage Sensor is a combination wireless and USB sensor that connects to a computer or tablet device through Bluetooth, and can also connect to a computer with a USB cable (included). The sensor measures voltage in the range between -15 volts (V) and +15 V. The sensor has built-in overload protection. The PASCO Data Collection Software will display and analyze the measurements from the sensor.

The PS-3211 wireless voltage sensor is ideal for studying fundamental concepts of electricity and studying the construction of electrical circuits. In chemistry lessons, the sensor helps students to investigate redox reactions, the potentials of electrolytic elements, and the effect of the strength of the solution on the generated potentials. Using the PS-3211 voltage sensor, it is possible to measure:

  • the electrical energy generated by an electrochemical battery
  • energy generated by a small wind turbine or other renewable energy sources
  • voltages on a section of a simple circuit (Ohm’s law/ Kirchhoff’s law)
  • the induced voltage in a wire coil when a magnet passes through it (Faraday’s law of induction)

Special Features

  • Simplicity: Simply connect the sensor to the device itself and measure the voltage in the range: ±15 V
  • The kit, in addition to the voltage sensor, includes wires for connecting (-) black and (+) red ending with a crocodile clip.
  •  The variable sampling rate for recording small rapid changes or experiments that last for hours, days, or weeks.
  •  High-speed sampling is available via USB connection in “burst mode”.
  • Long-lasting rechargeable battery (a fully charged battery ensures the operation of the sensor for 3 months).
  • Logging mode – collect data into the sensor memory, which is convenient for long-term experiments.
  • The sensor has built-in overload protection


To read data on a smart device or computer, you need to install the software:


  • Voltage Sensor (PS-3211)
  • Red wire with crocodile type terminal
  • Black wire with crocodile type terminal
  • USB to Micro USB charging cable

Combination with other sets

To study Ohm’s law, serial and parallel circuits, use a voltage sensor with a PS-3212 wireless current sensor and an EM-3536 electrical circuit kit.
