Monitoring and controlling CO2 levels is an important factor in building system optimization for both energy efficiency, building performance and occupant health and comfort. The COZIR CO2 sensor module can be operated with SMT’s wireless and wired data logger systems. Results can be graphed and analyzed alongside other critical building performance metrics such as temperature, RH, moisture content, air flow, differential pressure and heat flux.


Typical applications include HVAC and HRV system validation and optimization, as well as indoor/outdoor environmental CO2 validation monitoring.
