Wireless Current Sensor




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.

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.
  • Logs current data directly onto the sensor for long-term experiments. (Logging feature available with the release of PASCO Capstone 1.6 in April and SPARKvue 2.5 in June)
