Empowering educators worldwide, from schools and libraries to renowned institutes.

The future of education is here, and it fits right in the palm of your hand. Give your students the gift of engaging, interactive, and collaborative learning experiences with our SmartSchool Systems Microscope solutions. 

This sensor can be used to investigate the amount of CO2 in the air and how it changes over time.


Here are just a few example practical ideas you can achieve by using the Wireless Carbon Dioxide Sensor.

  • CO2 levels around a photosynthesising plant
  • Demonstrating the density of CO2
  • Respiration in small animals (e.g. insect larvae) at different temperatures
  • Monitoring CO2 in the local environment as a measure of ventilation or quality
  • CO2 level of expired and inspired air
  • Emissions from vehicle exhausts
  • Elevated CO2 in exercising and post exercise individuals
  • 0 to 100,000 ppm



  • Variances in classroom CO2 levels


  • Plant photosynthesis and respiration
  • Respiration of small organisms e.g. microbes, maggots
  • Measuring human CO2 production


  • Candle in Bell Jar (measuring CO2 emissions)

Works with the following Dataloggers:

VHub4 and VHub8
