Wireless Current

Measure currents of up to 1 A with built-in protection for the sensor against overload. Up to 1000 samples/second via Bluetooth. Up to 100,000 samples/second via USB in "burst mode" 

Wireless Conductivity

Wirelessly measure both conductivity and dissolved solids with this all-new design. Highly accurate with a fast response time and featuring built-in temperature compensation.

Wireless Light

The most versatile light sensor we've ever made, it is like having five sensors in one!

Measures illuminance, irradiance, UVA, UVB and UV Index and features RGB color detection.

Wireless Light Source

A key component of our Essential Physics Optics Kit, this rechargeable light source features four colored LEDs at the edges and a powerful RGB LED in the center. It can be controlled wirelessly using your computer or mobile devices.

Wireless Current Sensor Module

A component of our innovative Modular Circuits set, this module snaps into place anywhere in a circuit and wirelessly measures the current while reinforcing to students that current is measured in series while voltage is measured in parallel.

Wireless Hand Grip Heart Rate Sensor

Record physiological data without being tethered to an interface. Perform consistent monitoring or measure heart rate before and after exercise.

Wireless Exercise Heart Rate Sensor

Ideal for measuring heart rate when an activity requires students to use their hands. The chest strap is adjustable and data can be transmitted wirelessly up to 10 m away.

Wireless Blood Pressure Sensor

Measure both systolic and diastolic arterial blood pressure (mmHg) as well as heart rate. Includes a standard blood pressure cuff.

Wireless Load Cell/Accelerometer

Designed to be placed anywhere in a PASCO Structures system to measure tension & compression forces as well as acceleration (x,y,z and resultant).

Additional Wireless Products

While they don't utilize Bluetooth® 4 technology, the Wireless Spectrometer and Polarimeter can connect to devices using either USB or Bluetooth Classic connectivity.

Wireless Spectrometer

Connects to tablets and computers via Bluetooth or USB for introductory spectrometry applications, providing high accuracy and resolution at a low cost.

Wireless Polarimeter

Determine degree of optical rotation of the plane polarized light, and share the results with either Bluetooth or USB connectivity.


Over 80 plug-and-play sensors that connect to PASCO interfaces cover an extremely wide range of applications.
