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 …

Indoor TVOC Monitor with Raspberry PI Makerfabs

· For getting the TVOC reading, the SGP30 sensor was connected with raspberry Pi via I2C. For controlling and computing, I used the Raspberry platform instead of the singlechip that Raspberry has more strong computing ability. Besides, I had to prepare the speak and the audio coding part for voice reminder. The Raspberry Pi has to convert the text to audio what the speaker play. I also had to ...

How Does a TVOC Sensor Actually Work? Kaiterra

While labbased measurements may be highly accurate, they are unable to provide a continuous measurement of TVOC, which is incredibly important and, some may even argue, more important than having a perfectly accurate value for a specific gas. What Is an MOS Sensor? For the continuous monitoring of TVOC, MOS sensors are generally used. This is a broad category, and sensors across …
