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 …

How does Atmotube VOC sensor work?

Calibration of Atmotube TVOC Sensor. The Sensirion SGP is a broadband VOC detector, which is capable of detecting various VOCs and therefore TVOC. Sensirion’s SGP gas sensors are calibrated using ethanol since ethanol serves as a stable, reliable and economical proxy for TVOC. This is verified by linking the SGP sensor response to ethanol with the response to the ISO normed two kinds of …

VOC Sensors and Monitors - Volatile Organic Compounds

Both sensor types are non-selective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors are more resilient and can detect a wider variety of …
