Formaldehyde and Total VOC (TVOC) Commercial Low-Cost ...

The scaling factor S, defined as S = S sensor /S tenax, is plotted in Figure 15, where S sensor is the TVOC concentration given by the sensor in µg/m 3 equivalent toluene and S tenax is the corresponding TVOC concentration measured via the reference method. A scaling of 1 means that the sensor has been well calibrated and that the result can be seen as an absolute value. The bigger the ...

MiCS-VZ-89T a low power air quality sensor -

A low power sensor that can measure at the same time both carbon dioxide (CO2) and Volatile Organic Compounds (tVOC) is probably too good to be true. Yet the MiCS-VZ-89 does this, among some other appealing features like supply (in the T variant), I2C communication, calibration-free high sensitivity and a small size factor. Its price is also a plus.

About TVOC and the Laser Egg+ Chemical

How the Laser Egg+ Chemical measures TVOC? A metal-oxide-semiconductor(MOS) sensor is used in the Laser Egg to measure TVOC concentration. To ensure measurements remain accurate throughout the sensor’s lifetime, the sensor is continually self-calibrating: the lowest reading is used as a baseline, and all given TVOC readings are relative to this baseline. For the first 5 minutes of powering ...
