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.
Cellular Respiration and Carbon Cycle
In this lab, students use a carbon dioxide sensor to compare the respiration of dormant bean seeds with germinating bean seeds. Students will observe the contribution of cellular respiration to the global carbon cycle.
Metabolism of Yeast
Students use a carbon dioxide sensor to compare the metabolic rate of yeast in aerobic and anaerobic conditions.
Respiration of Germinating Seeds
Students use a carbon dioxide gas sensor to explore the energy requirements of seeds moving from dormancy to germination.
Energy Dynamics
Students set up a variety of simple detritus-based model systems to estimate energy flow and carbon cycling within an ecosystem. Students set up their ecosystem with a known detritivore, a known decomposer, or a combination of...
Plant Respiration and Photosynthesis
Students use a carbon dioxide gas sensor to measure the rates of photosynthesis and respiration in spinach leaves.
Blockly Extension: Photosynthesis and Carbon Dioxide Emissions
Students use a carbon dioxide sensor and Blockly code to estimate how many actively photosynthesizing spinach leaves it would take to offset the excess carbon dioxide they add to the air from everyday activities.
