Wireless Temperature Sensor - PS-3201


Easy-to-use, rugged (dust proof and water resistant) and with high resolution, the Wireless Temperature Sensor also connects directly to all your devices without the need for an interface.


The Wireless Temperature Sensor can be used anywhere you'd use a digital thermometer, but does so much more to connect students directly to the data in real time.

This durable, wireless, high-resolution sensor features a stainless steel temperature probe for the most demanding of applications. It can be used in a wide array of experiments and activities as it measures small but significant temperature changes produced by chemical reactions, convection currents, and even skin temperatures.

Students can access instant temperature readings but also continuously monitor, log and plot temperature data in SPARKvue on nearly any connected device.

Note:  The rugged sensor housing/handle is rated for temperatures of -10 ºC to 40 ºC. This means it cannot be subjected to the same extremes as the stainless steel probe. For extremely low or high temperature applications we recommend the Electrode Support to keep the sensor in the proper position during experiments.

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.
  • Features convenient Bluetooth wireless connectivity and long-lasting coin cell battery
  • Logs temperature data directly onto the sensor for long-term experiments.
  • Dust, dirt and sand proof and water resistant (1 meter for 30 minutes)

Bluetooth Low Energy Wireless Connectivity

Required Software:

PASCO products that use Bluetooth® Low Energy connectivity (wireless sensors, Smart Carts, and the AirLink) require the latest versions of our software.

PASCO Capstone is available for Mac and Windows. SPARKvue is available for Mac, Windows, iOS, Android and Chromebooks.

Additionally, the Wireless Motion Sensor and Wireless Smart Carts can be connected via Bluetooth and used with our MatchGraph app.

Compatibility/System Requirements

Any current model Chromebook, Mac, iPad, iPhone, Android tablet or phone will support direct connection to PASCO Bluetooth Low Energy devices. Also, any Windows 10 device with Creators Edition 1703 or later will support direct connection.

Chromebook users MUST have the latest firmware updates for ALL wireless sensors in order to use them without the USB Bluetooth Adapter. Full information.

All other Windows computers/tablets, older Macs, and Chromebooks without updated sensor firmware currently require the PS‑3500 USB Bluetooth Adapter to connect to PASCO’s Bluetooth Low Energy devices.

Full compatibility details are available, including compatibility information for older computing devices.


Independent datalogging 

Long term data collection directly on the sensor

In logging mode wireless sensors collect data to their onboard memory for hours, days, weeks or even months at a time without needing to be connected to a computer, tablet, Chromebook or smartphone.

When the experiment is concluded, simply connect the sensor to a device running PASCO software and download all the measurements it recorded.



Take a look at how easy it is to get connected and collect data with our Wireless Temperature Sensor or the rest of our new line of simple, powerful and cost effective Bluetooth® Smart devices.
