Aqara TVOC Sensor (review) – Homekit News and Reviews

· The TVOC sensor is, for what you get, quite reasonably priced (it’s currently on for just under €50) and can be found in a few online stores in Sweden. By contrast, the Eve Room (v2), is selling for practically double the price, and as of the time of writing, still uses Bluetooth. Putting that topic to one side, the version I have here today is the Chinese version, hence the packaging sporting most …

How Does a TVOC Sensor Actually Work?

What the sensor is actually measuring is the electrical resistance of this metal-oxide 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 …

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 tVOC-equivalent estimation based on the sensor's outputs history, but as such these 'equivalent estimations' may slightly vary between use-cases and …
