About TVOC and the Laser Egg+ Chemical

How the Laser Egg+ Chemical measures TVOC? A metaloxidesemiconductor(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 selfcalibrating: 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 ...

Adafruit SGP30 TVOC/eCO2 Gas Sensor

· The sensor to sensor variation of SGP30 in terms of sensitivity is very good as each of them is calibrated. But the baseline has to be determined for each sensor individually during the first Operation. To make that easy, SGP lets you query the ''baseline calibration readings'' from the sensor with code like this: uint16_t TVOC_base, eCO2_base;

Aqara TVOC Sensor (review) – Homekit News and Reviews

· The TVOC sensor in HomeKit is much like most other sensors in that with the arrival of iOS14, practically all sensors were removed from the tile section of the Home app, and placed above and collated into sections. This unfortunately means seeing the readings involves going into the relevant ‘circle’ and tracking down the appropriate sensor to check its readings. I can still see the logic ...

BME680 TVOC output does not seem correct

· The BME680 is a great sensor to track tVOC levels, but is not selective to specific compounds, and as other sensors working on a similar MOX sensing technology, such devices cannot output an absolute tVOC level. One could derive a tVOCequivalent estimation based on the sensor''s outputs history, but as such these ''equivalent estimations'' may slightly vary between usecases and …
