Wireless CO2 Sensor

The Wireless CO2 Sensor is a combination wireless and USB sensor that connects to a computing device through Bluetooth , and can also connect to a computer with a USB cable (included). The sensor measures carbon dioxide concentration in the range between 0 parts per million (ppm) and 100,000 ppm.


Use this wireless sensor to measure the concentration of Carbon Dioxide gas in a closed system or open environment. Study core topics (including photosynthesis, respiration, and carbon cycling) with this versatile probe. CO2 data can be logged directly on the device for long term life science and environmental science studies. New Accessory:  The Dissolved Water Proof CO2 Sleeve (PS-3545) shields the sensor from water, but is permeable to CO2 allowing for measurements of dissolved carbon dioxide levels.

Typical Applications

This PASCO SCIENTIFIC opens up new applications for this carbon dioxide sensor.

  • Measure CO2 uptake during photosynthesis in a terrarium
  • Compare indoor vs. outdoor CO2 levels
  • Study cellular respiration of yeast
  • Conduct chemical reaction studies


  • Sensor
  • 250-mL sampling bottle
  • USB charging cable

Investigate the relationship between exhaled carbon dioxide concentration and breath hold duration.

The Wireless CO2 Sensor allows you to gather evidence of a plant undergoing photosynthesis and respiration within minutes.
