The JQAW-8 series sensor measures CO2 concentrations and can be utilized as an indicator of occupancy. This approach drives a ventilation control strategy based on actual occupancy while maintaining ASHRAE recommended per-person ventilation rates. Over-ventilation can be reduced, energy can be saved, and air quality can be optimized by including the CO2 Sensor in your project.

Sensor and transmitter integrated design, It's suitable for indoor environment measurement of CO2,and also can be applied to the high concentration  occasions in long time.
