Introduction
The Wireless Oxygen Gas Sensor measures oxygen gas
concentration in percent (%) and parts per million (ppm)
oxygen. The sensor also measures temperature, relative
humidity, and absolute humidity. It can be used to study
cellular respiration, photosynthesis, air quality, oxygen
cycling, and the rate of oxygen production in chemical
reactions.
Using the sensor for the first time
Perform the steps below when using the sensor for the
first time. Detailed steps of each procedure are found in
separate sections of the instruction sheet.
1. Install the sensing element.
2. Charge the battery.
3. Connect the sensor to software.
4. Calibrate the sensor.

To install the sensing element
1. Unscrew the stopper from the sensor by turning
the stopper counterclockwise.
2. Remove the sensing element from the storage
bottle, then connect it to the sensor (Figure 1).
CAUTION: Make sure that the temperature and
humidity sensor does not get wedged under the
sensing element.
3. Screw the stopper back on the sensor.
NOTE: The sensing element only needs to be installed
when using the sensor for the first time. The sensing
element will not need to be removed until replacement is
necessary (at least two years).
Figure 1. Installation of the sensing element.
To charge the battery
1. Connect the micro USB cable to the micro USB
port on the sensor then connect the other end of
the cable to a USB charger.
2. Allow the battery to charge for at least three
hours. The battery status LED will turn green
when fully charged.
NOTE: The sensor can remain connected to a power
source when fully charged without damaging the
battery. The sensor automatically stops charging the
battery when fully charged.
To connect the sensor to software
The sensor automatically connects with the software
when connected to a device via USB. Use the procedures
below to connect the sensor to the software via Bluetooth.
SPARKvue
1. Press and hold the power button until the
Bluetooth status LED starts flashing red.
2. Open SPARKvue and select Sensor Data.
3. Under Connected Devices, select the sensor that
matches your device ID.
PASCO Capstone
1. Press and hold the power button until the
Bluetooth status LED starts flashing red.
2. Open Capstone and click Hardware Setup.
3. Select the sensor that matches your device ID.
To calibrate the sensor
The sensor should be calibrated before using the sensor
for the first time. It is not necessary to calibrate the sensor
each time the sensor is used. Calibration is recommended
if the O2Concertation reading for an atmospheric sample
is greater than ±1% from 20.9%.
SPARKvue
1. Collect an atmospheric air sample (see the
Collecting Samples procedure).
2. Connect the sensor to SPARKvue and set up
data collection.
3. Select the Hardware Setup icon.
4. Select the Calibration icon.
5. Select Calibrate.
6. Select OK to confirm calibration.

PASCO Capstone
1. Collect an atmospheric air sample (see the
Collecting Samples procedure).
2. Connect the sensor to Capstone.
3. In the Tools palette, click Calibration.
4. Select Concentration then click Next.
5. Select One Standard (1 point slope) then click Next.
6. Click Set Current Value to Standard Value.
7. Review the calibration then click Finish.
Collecting Samples
To collect an atmospheric air sample
NOTE: It is recommended to perform this procedure
outside of a building to collect a fresh sample.
1. Hold the sample bottle upright and open to the air.
2. Insert the stopper of the sensor into the bottle to
seal the bottle.
To collect expired air or other gas samples
1. Place the sensor inside a plastic bag.
2. Press any atmospheric air out of the bag.
3. Use a tube to fill the bag with the gas sample.
4. Secure the bag closed round the tube to contain
the gas sample and exclude atmospheric air.
WARNING: Do not allow the sensor to contact liquids.
CAUTION: Do not clean the sampling bottle in a
dishwasher or autoclave.
LED Status
The status LEDs operate as follows:
Bluetooth LED Status
Red blink Ready to be connected to software
Green blink Connected to software
Yellow blink Remotely logging data
Battery LED Status
Red blink Battery needs to be replaced soon
Green solid Battery is fully charged
Yellow solid Battery is charging
Storage
Under 20.9% ambient O2, the lifetime of the sensing
element is estimated to be 2 years or longer. The lifetime
of the sensing element will be affected by several factors,
including storage temperature, pressure, and availability
of oxygen. It is recommended to cover the stopper with
the included sample bottle or sensing element storage
bottle when not in use. This will limit its exposure to
oxygen and maximize the lifetime of the sensing element.
How the sensor works
The oxygen sensing element is a galvanic fuel cell with a
gas permeable membrane at one end. The fuel cell
contains an electrolyte, anode, and cathode. When
oxygen enters the fuel cell through the membrane, a
chemical reaction between the metallic cathode and
anode and the electrolyte occurs. This chemical reaction
produces a voltage. The voltage produced is proportional
to the concentration of oxygen present.
