Online, high quality CO2 monitoring

Carbon Dioxide (CO2) levels are a good indication of whether a room has sufficient ventilation. Good air quality is important for productive learning and working environments and reduces the risk of virus transmission. Unfortunately most NZ buildings currently have no consistent monitoring of CO2 levels

co2mon.nz provides a complete package consisting of a physical CO2 monitor to provide immediate in-room feedback on CO2 levels to occupants, combined with an online dashboard offering historical records and trends of CO2 levels for each CO2 monitor, enabling a centralised view across an entire building, campus or facility.

co2mon.nz also runs a sponsorship program to help NZ schools to quickly and simply deploy high-quality CO2 monitoring to their classrooms at no cost to the school*.

co2mon.nz CO2 monitors are based on an open source design published by Oliver Seiler of Wellington which uses the highly accurate Sensirion SCD30/SCD40 CO2 sensor.
