I am playing with a CCS811 gas sensor (cjmcu-811) and can’t seem to find a capability for VOCs? Are there any other alternatives for registration? ---

Hi Marlon, Your post has been moved to ‘developers’ as this is the most likely place you will get an answer about adding device capabilities. You can see the full list of capabilities here : [https://developer.athom.com/docs/apps/tutorial-Drivers-Reference.html](https://developer.athom.com/docs/apps/tutorial-Drivers-Reference.html) Or you can checkout creating your own capabilities here : [https://developer.athom.com/docs/apps/tutorial-Drivers-Capabilities.html](https://developer.athom.com/docs/apps/tutorial-Drivers-Capabilities.html) ---

It did take a while but I found it. The capability is called **PM2.5** “Atmosperic particulate matter” and can be set using “measure\_pm25” ---

Those aren’t the same, though: PM2.5 applies to very fine dust(-ish) particles, whereas VOC applies to organic chemicals (things like solvents). ---

Ok thanks for the info. ---

There’s this new sensor that has Air pollution detector (TVOC, CO2) Perhaps someone would write an app to support it. > **[MicroBot Alert](https://shop.microbot.is/products/568cf1d6-908b-4b1c-aee9-a173c51632b8)** > > Sense is the portable smart sensor that measures atmospheric variables including temperature, moisture, air pressure, light intensity, noise level, CO2 level, VOCs, movements.

Does anyone have the microbot? Any experience? The website states it supports google, alexa and ifttt. So homey should be able to get the data ---

But their shop is closed, it is sold out on Amazon and the reviews says they cannot get in touch with the company? If you want to measure VOC and don’t want to build your own sensor ([Homeyduino BME 680 BSEC library](https://community.homey.app/t/homeyduino-bme-680-bsec-library/25078)) at least awair and airthings have sensors which are supported in Homey. However they’re not as small as the microbot, and they don’t measure lux and sound. ---

A friend of mine bought the microbot, but it was not any good, most of the measurements were off. Just look for another one.
