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, but I’m not sure it helps when you have a heap of sensors throughout the home. This is not …

Finding the Best TVOC Sensor: BME680 vs CCS811 vs SGP30

· Rather, it uses the gas sensor readings to calculate the IAQ (Indoor Air Quality). This scale is from the German Federal Environmental Agency’s guidelines on VOCs. (According to the BME680 data sheet) The gas sensor measurements, worst case, draw 18 mA from your power supply. All the other measurements are < 1mA. Not bad. Cost/Availably

How Does a TVOC Sensor Actually Work? Kaiterra

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. This means that for a change in resistance to be mapped to a change in VOC levels in ppb, either the exact gas in the air must be known, or an …

Understanding TVOC: What You Need To Know About Volatile ...

If you have an air quality monitor with volatile organic compound detection capabilities, you will see your readings in terms of TVOC. Unfortunately, TVOC isn’t uniformly defined. Many standards include different VOCs in their TVOC grouping, or assign different weights when calculating TVOC. This can make the definition of TVOC difficult to parse, as we can’t say definitively what VOCs are in TVOC.
