Indoor Air Quality Sensors. Historically, three variables have been used to define indoor air quality; temperature, humidity and CO 2. It is becoming more widely accepted that volatile organic compounds (VOCs) such as smoke, cooking odours and outdoor pollutants impact the air quality. VOCs can also be emitted from building materials, furnishing and operational equipment such as photocopiers ...
Model : N-V0100 Navter's VOC Monitor is a portable desktop and wall mountable instrument that measures VOC concentration in air. The instrument displays the real-time value of VOC concentration in ppm, temperature and relative humidity. It has built-in storage for continuous data logging and Wi-Fi connectivity for easy access of data log.
One candidate sensor principle for direct monitoring of even sub-ppb level VOC concentrations are metal oxide semiconductor (MOS) gas sensors [13,14], but gas-sensitive field effect transistors (GasFETs), , based on silicon carbide (SiC-FET), have also proven their suitability for this task . For simplification, we will concentrate on MOS sensors in the following discussion, but many ...

VOC sensors can be used to detect high pollution that might occur when special equipment is being used or when potent chemicals from cleaners are released into the air. CO 2 sensors would specifically reduce ventilation during unoccupied periods, but VOC sensors might maintain ventilation rates during unoccupied periods if a significant pollutant level in the building is detected.
The sensor will be sensitive to a wide variety of VOCs, rather than to one specific individual VOC. How does the change in resistance become a TVOC reading in ppb? Although similar, different VOCs will have slightly different reactions - the same increase in formaldehyde and in ethanol might not lead to the exact same change in resistance on the sensor.
Indoor Air Quality in Classrooms and COVID19. April 12, 2021. The effect of poor indoor air quality in classrooms has been known for years. Chronic illnesses, reduced cognitive abilities, sleepiness, and increased absenteeism have all been attributed to poor IAQ - specifically elevated CO2 levels. What's more concerning today is the effect ...
