Introduction

The Wireless Temperature Sensor measures temperature over a

range of -40 °C to 125 °C. The stainless steel temperature probe

is more durable than a glass thermometer and is able to work in

a wide variety of situations. The temperature measurement is

transmitted wirelessly through Bluetooth and is recorded and

displayed by PASCO Capstone or SPARKvue on a connected

tablet or computer. Since each sensor has a unique device ID

number, more than one can be connected to the same computer

or tablet at a time.

The Wireless Temperature Sensor is powered by a replaceable

three volt coin cell battery and is well-suited for continuous

recording and discrete measurements. The sensor is designed

to optimize the battery usage time.

The sensor housing is water resistant, but immersing it in water

may cause a loss of wireless connection. Only the Temperature

Probe should be exposed to the substance being measured. Do

not immerse the sensor housing in boiling hot water.

Calibration

Calibration is generally not necessary when using the Wireless

Temperature Sensor, especially if you are measuring a change

in temperature rather than absolute temperature values.

However, it is possible to calibrate the sensor using the following

procedures.

Prepare for Calibration

Calibration will require an ice water bath, a container of hot

water, and a thermometer. The sensor will need to be connected

to PASCO Capstone or SPARKvue for these procedures; see

Set up the software for details on connecting the sensor.

SPARKvue

1. Place the thermometer into the container of hot water.

2. Create a Graph display with Temperature as one of the

measured quantities, as described under the SPARKvue

section of Set up the software.

3. Click the Show Hardware Setup button in the bottom

right of the Experiment Screen, then click the Calibrate

measurement icon next to Temperature to open the

Calibrate Sensor menu.

4. Check to make sure that the selected sensor is Wireless

Temperature Sensor, the measurement is Temperature

(°C), and the Calibration Type is 2 point (Adjust Slope

and Offset), then click Continue.

5. Place the Wireless Temperature Sensor into the container

of hot water. Wait for the temperature reading to stabilize.

6. Using the thermometer, determine the temperature of the

hot water. Enter this value into the Standard Value box

under Calibration Point 1, then click Set Calibration.

7. Remove the thermometer and Temperature Sensor from

the hot water container, wipe them both dry, and place

them into the ice water bath. Wait for both the thermometer

measurement and the sensor reading to stabilize.

8. Using the thermometer, determine the temperature of the

ice water. Enter this value into the Standard Value box

under Calibration Point 2, then click Set Calibration.

9. Check your new calibration for accuracy, then click OK.

ice water. Enter this value into the Standard Value box,

then click Set Current Value to Standard Value.

9. Review your calibration to ensure it is accurate, then click

Finish.

Battery usage

The Wireless Temperature Sensor contains a three volt coin cell

battery (CR2032). Battery life is very important to making the

sensor simple and always ready to use. Therefore, like all

PASCO wireless products, the Wireless Temperature Sensor is

designed for long battery life. For example, after several minutes

of inactivity, the sensor turns itself off to preserve the battery.

The included battery should provide 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 several months, we recommended

that you remove the battery and store it separately 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 battery requires removing

the Battery Compartment Door on the bottom of the sensor,

removing the old battery, installing a new battery of the same

type, and replacing the Battery Compartment Door. This

procedure requires a coin and a CR2032 three volt battery, such

as those included in the PS-3504 Coin Cell Battery Pack.

NOTE: This type of battery is also commonly

available in electronic and commercial stores.

Removing the Battery Compartment Door

Hold the sensor with the

bottom side up. Insert a

coin into the slot and use it

to turn the Battery

Compartment Door

counterclockwise until the

indicator on the door is

aligned with the second

mark on the sensor.

Turn the sensor so the

bottom side is down,

allowing the Battery

Compartment Door to drop

into the palm of your hand. Make sure that the battery door

gasket stays on the door. The gasket is an "O-ring" that is held

in place by the tabs on the door. Do not touch the inside of the

battery compartment, as this may damage the sensor.

Replacing the battery

Remove the used battery from the Battery Compartment Door

and replace it with a new battery of the same type. Note that the

battery is held in place by the small tabs on the door. The side of

the battery with the "+" on it should be against the door.

Product Guide | 012-14647D

Replacing the Battery Compartment Door

Put the Battery Compartment Door,

along with the new battery, back onto

the sensor. Align the indicator on the

door with the second mark, then use

the coin in the slot to turn the door

clockwise until the indicator is aligned

with the first mark on the sensor.

When disposing of the battery, follow

the battery disposal guidelines under

Regulatory information.

Temperature Probe Maintenance

Rinse and dry the temperature probe before storing the sensor.

The probe is stainless steel and the diameter (5 mm, or 0.197")

is compatible with standard stoppers.

Troubleshooting

•If the sensor loses Bluetooth connection and will not

reconnect, try cycling the ON button. Press and briefly hold

the button until the status LEDs blink, then release the

button.

•If the sensor stops communicating with the computer

software or tablet application, try restarting the software or

application and attempting to connect again.

•If the problem persists, press and hold the ON button for

ten seconds, then release the button and start the sensor in

the usual way.

•If the above steps do not fix the connection problem, turn

Bluetooth off and back on for your computer or tablet, then

retry.
