Using Data Streamer
Use Data Streamer to stream data from sensors, record the data, and visualize the data in different displays.
Calibrating sensors
If sensors are not measuring values as expected, you may need to calibrate the sensor.

What is Data Streamer?
Use PASCO Data Streamer to collect data with PASCO Wireless Sensors and stream the data into an Excel workbook.
Installation and Setup
To stream data from PASCO Wireless Sensors to Excel, you need to install PASCO Data Streamer and enable the Excel Data Streamer add‑in.
Overview of the Excel Workbook
After connecting PASCO Data Streamer to Excel, Excel displays four customized spreadsheets by default. The two sheets used with PASCO sensors are the Data In and Settings sheets.
Using Data Streamer
Use Data Streamer to stream data from sensors, record the data, and visualize the data in different displays.
- Stream Data
  To stream data, connect a sensor to the PASCO Data Streamer app, then connect the app to Excel.
- Display Data
  Visualize data in a variety of ways including a graph, bar chart, and digital meter.
- Manually Sample Data
  Manually record data points instead of continuously streaming data. This method is useful for displaying a sensor measurement versus a non-sensor measurement.
- Record and Replay Data
  Record data to a .csv file to replay data at a later time.
- Calibrating sensors
  If sensors are not measuring values as expected, you may need to calibrate the sensor.
- Sample Workbook Files
  Learn how to use the sample workbook files provided on the Data Streamer page on the PASCO website.

Calibrating sensors

If sensors are not measuring values as expected, you may need to calibrate the sensor.

It is not possible to calibrate sensors in PASCO Data Streamer or Excel. However, it is possible to calibrate the sensor in SPARKvue or PASCO Capstone and save the calibration to the sensor.

To calibrate your sensor:

Disconnect it from PASCO Data Streamer.
Connect the sensor to SPARKvue or PASCO Capstone.
Tip: SPARKvue is available as a free app for Chromebooks, iOS, and Android devices.
Perform a calibration in SPARKvue or PASCO Capstone.
Disconnect the sensor from SPARKvue or PASCO Capstone then reconnect it to PASCO Data Streamer.
