Wireless Voltage - Current Sensor 5V 0.1A

Wireless datalogging sensors


Data Harvest

Product Description


Combines a voltage and current sensor in one package. It can be used to measure both electric current and the potential difference across a component in low voltage AC or DC circuits.  

The four 4 mm sockets (2 for Voltage and 2 for Current) allow for connection to most standard available electronics kits and school based power supplies using 4 mm plug leads (not supplied).

Bluetooth | USB | Huge Battery Life | Independent Logging  

Example Science Experiments

  • What changes the current in a circuit?
  • Good and bad conductors
  • Long wires, less power?
  • Faraday’s induction of voltage in a coil
  • Efficiency of an electric motor / generator 
  • Capacitor time constant
  • Alternative power investigations e.g. solar cells, water power, wind energy, etc.
  • Connecting resistors together
  • Electrical characteristics of a LED or diode
  • Faraday’s induction of current or voltage in a coil
  • Dynamo effect 
  • Capacitor discharge, charge and energy stored 
  • Diodes: A.C. diode rectification
  • Reactance and phase in a capacitor
  • Calibration of a thermometer
  • Resonance in a series LCR circuit
  • Impedance change with frequency increase 


Ranges Voltage ±5 V, Current ±0.1 A (±100 mA)
Resolution 1 mV, 0.1 mA
Connectivity USB or Bluetooth
Battery Internal 1300 mAh.  A single charge can power the sensor for a whole year.



Seriously Smart Wireless Bluetooth Sensors

Designed with new and existing customers in mind!

A new Smart Wireless range of science sensors that also function as data loggers in their own right using Bluetooth or USB connectivity. The new Bluetooth wireless sensors include a huge battery life and can be mixed & matched with existing SmartQ Sensors & Data Loggers!

Works with SmartQ

Our wireless sensors can be used in combination with other Smart Wireless Sensors or data loggers in the EasySense range, even more amazingly is that with the addition of a V-Hub sensor link you can continue to enjoy using your existing SmartQ sensors at the same time!

The Power of Smart Wireless

Our Smart Wireless sensors build on the design of our legendary intelligent SmartQ Sensors but adds Bluetooth wireless connectivity allowing users to connect to tablets and mobile phones using the new EasySense2 Software. 

Digital Technology
Our digital sensor technology brings science to the classroom providing you with a robust, accurate and repeatable teaching experience from the start.


Auto Calibration
We have taken the hassle out of setting up your experiments with our pre-calibrated, auto identify sensor technology, every sensor is ready to use out of the box.


USB Charging
Our Smart Wireless sensors are powered by an internal battery and can be charged via a standard USB charger.


Designed for Mobile
With the included Bluetooth connectivity the new Smart Wireless Sensors can connect to Tablets, Mobile Phones, Laptops and Desktop Computers


Smart Connectivity

Not only do the Smart Wireless Sensors connect to multiple tablets and mobile devices via Bluetooth but they can also connect directly to a desktop computer and be used just like a traditional data logger whilst offering faster data transfer rates.
