Product Summary
The Wireless Current Sensor Module is designed for use with PASCO Modular Circuit sets. It can be placed anywhere in a circuit and provide current measurements at that point.
Measure currents of up to 1 A and transmit the collected data wirelessly to your computers, Chromebooks, tablets or smart phones.
This sensor is included in the Modular Circuits for Essential Physics Set and is an optional accessory for the Basic Modular Circuits Set. In that set a multimeter may be used to collect voltage and current measurements or you can use our Wireless Current Sensor Module and/or our Wireless Voltage Sensor which can be used in conjunction with PASCO software for data collection and analysis, providing a deeper conceptual experience.
Note: 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 do not recommend connecting it directly across a battery or other voltage source without a resistive load.
The sensor includes an Overcurrent Alarm for protection against harmful current levels. The sensor must be turned on for this function to operate.

High School / Physics
Students construct a circuit that produces current in an inductor and use a compass to investigate its properties. They remove the batteries and use a magnet to produce current in the circuit by moving it by the inductor. They...
High School / Physics
Students construct a circuit that charges and discharges a large capacitor through a light bulb. They create a model for their observations and test the model with current sensor data. They measure the voltage across a smaller...
High School / Physics
Students construct a circuit consisting of two resistors in series and then in parallel. They measure the voltage across the resistors, and the current through the resistors. From their measurements they can infer Kirchhoff's...
High School / Physics
Students measure the current and voltage across a resistor while varying the output voltage, A graph of voltage versus current will reveal Ohm's Law. This version uses the potentiometer module to vary the voltage.
College • High School / Physics
The purpose of this experiment is to verify Ohm’s Law for commercially manufactured resistors and to examine the limits of validity for Ohm’s Law. The behavior of resistors, a diode, and a light bulb are examined.
High School / Physics • STEM
Students create a Blockly program that tests a battery using measurements from a voltage sensor and current sensor. They modify the code to improve reliability and accuracy.
Advanced Placement • College / Physics
Students construct a circuit that produces current in a coil and use a magnetic field sensor and current sensor to investigate its properties. They determine the direction of the magnetic field in the coil and the direction of...
