How Does a TVOC Sensor Actually Work? Kaiterra

What the sensor is actually measuring is the electrical resistance of this metaloxide layer. This real time measurement and output of resistance is the first step in obtaining our TVOC reading. The change in resistance across the surface of the sensor is directly proportional to the change in concentration of the target gas(es). The exact degree to which the resistance will change (that is, the ratio or equation that …

Air quality sensors in Air Purifiers. How accurate are they?

· TVOC sensors contain elements and are not designed to run continuously; they have to be switched off for intervals; otherwise, they lose accuracy and will give false readings, so TVOC readings are not continuous. They also have short service life intervals, usually a maximum of 2 years. At InovaAir, we back all of our products with a 5year warranty and will not implement a sensor with a ...
