Introduction
The PASCO Wireless Temperature Link is a versatile
measuring device that can connect to a computer or mobile
device wirelessly through Bluetooth (BLE). It has a
PS-2135 Fast Response Temperature Probe with a wide
temperature range (-35 to +135°C). The temperature
measurement is transmitted wirelessly through Bluetooth
(BLE) and recorded and displayed by the PASCO software
such as SPARKvue or PASCO Capstone. SPARKvue
allows the sensor to work with a computer or with a mobile
device such as a tablet or smart-phone when the sensor is
connected. PASCO Capstone will work on a PC or Mac.
Data Collection Software
See the PASCO web site at www.pasco.com/software for
help in selecting the right PASCO software and to check for
the latest versions.
Features
The Wireless Temperature Link is powered by a replaceable three volt coin cell battery (included) and is well-suited
for continuous recording and discrete measurements. The sensor is designed to optimize the battery usage time.
Since each sensor has a unique Device ID number, more than one sensor can be connected to a computer or
tablet at the same time.
The sensor housing is water resistant, but not waterproof. Immersing it in water may cause a loss of wireless
connection. Put only the Temperature Probe into the substance being measured.
Connect the Temperature Probe or other Apparatus
Put the 3.5 mm diameter plug of the temperature probe (or other apparatus) into the 3.5 mm diameter port on the
Wireless Temperature Link.
ON/OFF and Sleep Information
To turn the sensor on, press and hold the ON/OFF button. When the Battery LED shines red for a moment, release
the ON button. Then, the Bluetooth LED will blink. This indicates that the sensor is ready to be “paired” with a
device using the data collection software.

Using the Sensor
LED Information
The Bluetooth LED (light-emitting diode) and the battery LED operate as follows:
*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: Latest versions of SPARKvue and PASCO Capstone support logging. Check the PASCO Web page
at:www.pasco.com/software for the latest software version.
Calibrating the Wireless Temperature Link
•Calibration is not always necessary, especially if you are measuring a change in temperature rather than
absolute temperature values. However, it is possible to calibrate the sensor. For detailed information, see
Appendix B.
Battery Usage
•The Wireless Temperature Sensor includes a 3 V coin cell battery (CR2032). Battery life is very important to
making the sensor simple and always ready to use, so all of the PASCO wireless products are designed for
long battery life. For example, the sensor turns itself off after a short time of inactivity.
•We expect more than one year of battery life, but the actual amount depends on factors such as the data
collection sampling rate.
Sensor Storage
•If the sensor will be stored for many months, we recommend that you remove the battery to avoid damaging
the sensor in case of a battery leak.
Battery Removal and Replacement
•If the sensor’s battery status LED blinks red, the battery may need to be replaced. Replacing the small,
disk-shaped battery involves removing the Battery Compartment Cover on the bottom of the sensor, removing

Appendix B: Calibration
Calibration is not always necessary, especially if you are measuring a change in temperature rather than absolute
temperature values. However, it is possible to calibrate the sensor.
Prepare for Calibration
Calibration will need an ice-water bath, a container of hot water, and a thermometer. The sensor will need to be
“paired” with a tablet or computer, and the data collection software (for example, SPARKvue or Capstone) should
be running.
Capstone Calibration
1. Turn on the sensor. Start Capstone. “Pair” the Wireless
Temperature Link wirelessly to the computing device (e.g.,
computer) as explained earlier.
2. In Capstone, click the “Calibration” icon in the
Tools palette to open the “Calibration” window.
In Step 1, select the Temperature measurement

Theory of Calibration
One of the functions of the PASCO Data Collection Software (SPARKvue or PASCO Capstone) is to take the
stream of raw data from a sensor and transform it into the calibrated data that you see in the Graph, Table, and
other displays. If you do not calibrate a sensor yourself, the software uses a default calibration that is loaded when
the sensor is connected.
You can think of the software as taking in raw data and outputting calibrated data. When you perform a calibration,
the software redefines the linear equation that transforms the raw input data into the calibrated output data. The
linear function is of the form:
Calibrated Output = Slope x Raw Input + Offset
Or:
Raw Input = (Calibrated Output- Offset)/Slope
Highlight the Standard Value and enter the
thermometer temperature

PS-3220 Appendix B: Calibration
13
013-16067A
The function can be represented graphically as a line.
Two points, Pt 1 and Pt 2, define the line. In the two-point
calibration procedure, each point is reset by associating a
known standard value (for instance, the temperature of ice
water) with a raw input measurement that the sensor sends
out when it is in that standard. In a one-point calibration, only
one of the points is reset by the user.
Types of Calibration
There are three types of calibration: two-point, one-point
slope, and one-point offset. Any of these calibrations can be
performed on a single sensor, or simultaneously on multiple
similar sensors; however, for any given sensor, the software will automatically select the most typical calibration
type as the default setting.
Two-Point
In a two-point calibration, you reset two points to define a new
line. This type of calibration affects both the slope and the offset.
One-Point Slope
In a one-point slope calibration, you reset only one point. The
slope of the line changes so that the line intersects the new
point, while the offset (or Y-intercept) does not change.
One-Point Offset
In a one-point offset calibration, you reset only one point. The
line shifts so that it intersects the new point, but its slope
does not change.
Offset calibration is usually used to make one sensor agree
with another sensor. Due to normal variation among probes,
a second probe might read consistently higher than the first
probe. Normally this difference would be insignificant;
however, an offset calibration can be used to bring the
sensors into closer alignment.
