Product Summary
Measure changes in carbon dioxide (CO2) gas levels quickly and easily with the Wireless CO2 Sensor. The sensor is temperature compensated and can operate in high humidity environments. It employs live data to make core labs, such as photosynthesis, cellular respiration, and metabolism experiments engaging and impactful. With the ability to store more than 55,000 data points, this sensor enables studies to run overnight or throughout an entire weekend, making it ideal for long-term, carbon cycling investigations. The included 250-ml sample bottle supports analyses with multiple gas sensors.

Experiment Library
Perform the following experiments and more with the Wireless CO₂ Sensor.
Visit PASCO's Experiment Library to view more activities.
Decomposition
In this lab, students will investigate the rate of decomposition in different soil and substrate samples.
Photosynthesis and Cell Respiration in a Terrarium
In this lab, students will use an oxygen sensor, 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...
Plant Respiration and Photosynthesis
Students use a carbon dioxide sensor to measure the rates of photosynthesis and respiration in spinach leaves.
Plant Respiration and Photosynthesis
In this lab, students will monitor a plant's carbon exchange within a closed system in both light and dark conditions to determine the dominant metabolic pathway.
Determining Soil Quality
In this lab, students use carbon dioxide, conductivity, and pH sensors to determine the quality of different soil samples.
Photosynthesis
Guide students to measure the change in carbon dioxide (in a closed system) with a carbon dioxide sensor to facilitate an understanding of the relationship between carbon dioxide, respiration, and photosynthesis in plants.
