CO2 Sensors vs. VOC Sensors for IAQ - What's the ...

Unlike a CO2 sensor, a VOC sensor cannot indicate the rate of ventilation needed, only the level of VOCs in the air. It also cannot necessarily indicate whether safe or harmful concentrations of VOC contaminants are present. It can indicate a general change in the concentration of contaminants. This makes air quality sensors a better solution in applications where unusual, non-occupant-related ...

Adafruit SGP30 TVOC/eCO2 Gas Sensor

07/12/2020· eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use. Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values. Nice sensor right? So we made it easy for you to get right ...

VOC Sensor Capabilities and Limitations - Application Note ...

The BAPI VOC sensor provides a CO2 equivalent ppm output so that Ashrae’s popular CO2-based VRP procedure can be used for DCV; however, CO2 is not one of the VOCs that the sensor monitors. If your application needs to directly measure CO2, choose a CO2 sensor. Commissioning and Testing. BAPI’s VOC sensor is easily tested for proper operation. Many applications need to demonstrate sensor ...
