Volatile organic compounds (VOC’s) are organic chemicals that have a high vapour pressure at ordinary room temperature. Their high vapour pressure results from a low boiling point, which causes large numbers of molecules to evaporate from the liquid or solid form of the compound and enter the surrounding air. This is why it is important to monitor for VOC using a range of voc gas detector. We …

Today, metal oxide semiconductor sensors are almost exclusively used as VOC sensors in heating, ventilation and airconditioning technology. This sensor element measures the conductivity of the nanocrystalline metal oxide that is applied to a substrate. These sensors only permit the measurement of a relative gas concentration. As a result, it is not possible to specify a measuring range or

· Working with the sensor, I noticed that its VOC values are significantly higher than other similar sensors (for example, SGP30). Our company is now producing units with an SGP30 sensor inside, but for some reason we are looking for a replacement and paid attention to the BME680. The estimated values of CO2 and VOC equivalents are important to us.

Their sensors are developed to create a full 360 degree field of vision environmental view for use in autonomous vehicles, industrial equipment, 3D mapping and surveillance.
Most importantly, the VOC data is what leads me to believe something is actually wrong with the TP07 sensors. If all contamination levels are good and I open the window, the TP07 levels stay green/good (which is strange in itself). However, when I close the windows after being open a while, the VOCs will rise to yellow, without fail, leading the fan to kick on to about 56, and those levels ...
The main takeaways and perspectives for MOS VOC sensors in ventilation systems are summarised in the conclusion section. 2.

Aeroqual VOC Sensors. Aeroqual offers two types of VOC measurement sensors; Photoionization Detector (PID), and Gas Sensitive Semiconductor (GSS). Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors …
