Then the two switch and the VOCs track slightly above the CO2 during the community meeting period when it is mostly adults in the room. That’s because adults use more perfumes and colognes than kids, and therefore generate more VOCs than kids. Whether it’s kids or adults in the room, and whether they’re studying or eating, the chart shows that the VOC sensor output directly correlates to ...

BAPI’s VOC sensor offers the best of both worlds. It allows for ventilation based on occupancy as well as air contaminants. The BAPI unit does this because it has been optimized for DCV. Using a calibration algorithm, the sensor value is converted to an output with a high correlation to a CO2 level. This lets you use Ashrae’s more popular and straight forward occupany-based VRP schedule ...
The SGP40 VOC Sensor is a digital VOC (Volatile Organic Compounds) sensor module which incorporates SGP40, designed for air quality monitoring. It can be used to measure fire coal, natural gas emissions, cigarette/cooking smoke, and emissions from constructing activity, decoration material, furnitures, home appliances, then generate digital signals for triggering air treatment devices.
VOC concentrations in Air (Units of Measurement) Concentrations of chemicals in air are typically measured in units of the mass of chemical (milligrams, micrograms, nanograms, or picograms) per volume of air (cubic meter or cubic feet). However, concentrations may also be expressed as parts per million (ppm) or parts per billion (ppb) by using ...
