The Wireless Oxygen Gas Sensor measures gaseous O2 concentration as well as humidity and air temperature for a range of biology, environmental science, and physiology activities.

Accurate and easy to use, making it the perfect sensor to study photosynthesis, respiration, and oxygen cycling in the environment. With remote logging, experiments can go beyond the lab period and easily give students hours or days of data for analysis. The Wireless Oxygen Gas Sensor also contains sensors to measure ambient temperature and humidity as well as oxygen gas levels.


  • Bluetooth® and USB connectivity
  • 0-100% Oxygen Gas Concentration
  • ±1% Oxygen at constant temperature and pressure
  • Also reports ambient temperature and humidity
  • 2-3 year operating life with replaceable sensing element

No need for an interface.

All PASCO Wireless Sensors connect to computers, Chromebooks, and tablets, through Bluetooth 4. No other equipment required! Our software (SPARKvue or PASCO Capstone) allows students to see and analyze data in real-time.

Long-lasting, rechargeable battery

The Wireless Oxygen Gas Sensor draws as little current as possible. This provides you with a long battery life for lab activities. Our software also displays the battery level at all times. If it dips too low, connect the USB cable to charge while you collect data.

Battery and Logging

Stored Data Points Memory (Logging) 1 >25,000
Battery – Connected (Data Collection Mode) 2 NA
Battery – Logging (Data Logging Mode) 3 10 days

1 Minimum # of data points with all measurements enabled, actual results depend on enabled measurements.

2 Continuous use in a connected state until battery failure, actual results will depend on sample rate, active measurements, and battery condition.

3 Logging until battery failure, actual results will depend on sample rate, active measurements, and battery condition.

* Normal classroom use is the sensor in active use for 20min/lab for 120 lab periods/yr.

Visit PASCO’s Experiment Library to view all activities for this product.

Photosynthesis and Cell Respiration in a Terrarium

In this lab, students will use an oxygen sensor, a carbon dioxide sensor, and a temperature sensor to monitor a closed system (terrarium). After conducting their first study, students will be tasked with designing additional investigations…

Modeling an Ecosystem

In this lab, students will design and study three, small ecosystems. Students will manipulate system interactions while monitoring gas exchange, environmental conditions, and subject health.

Modeling an Ecosystem

In this lab, students use a variety of sensors to explore the use of terrariums as a closed system for environmental studies and design methods for exploring the interrelationships of biotic and abiotic variables within ecosystems.

Enzyme Activity (Oxygen)

Students will use an oxygen gas sensor to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
