LED Information

The Bluetooth and the Battery Status LEDs operate as follows:

For a wireless Bluetooth connection:

For a micro USB cable connection to a USB 

port

:

For a micro USB cable connection to a USB 

charger

Logging

: PASCO wireless sensors can either stream live data to a compatible device or log data (save it to the 

sensor’s memory). The data can then be uploaded to the device for display and analysis at a later time. Logging 
capability supports long-term or remote data collection while not connected to the device. 

Note: The latest versions of SPARKvue and PASCO Capstone support logging. Check the PASCO Web page at:

www.pasco.com/software

for the latest software version.

Set Up the Software

SPARKvue

Connecting the Sensor to a Tablet or a Computer via Bluetooth

For SPARKvue, select the Bluetooth icon. In the 

Wireless Devices

 list. The sensors are ordered by proximity 

to the device. Select the correct address that matches the Device ID XXX-XXX number found on the sensor. 
Select 

Done

.

Connecting the Sensor to a Computer with the Micro USB Cable

Connect the micro end of the included Micro USB Cable into the micro USB port on the side of the sensor. 
Connect the other end of the Micro USB Cable to a USB port on the computer, or into a powered USB hub 
connected to the computer.

In the SPARKvue

 

Home Screen, select a measurement from the list under the sensor’s name. A graph of the 

measurement versus time opens.
