Good morning from the 633 train going to Ottawa.

Wi-Fi. Ethernet. Now optional LTE. 📶 Model O can send indoor air quality readings to the cloud where a local network isn't the right fit. See how it works (Cat-M1 SIM + data plan required): visiblair.com/products/model…

In business class today going to Toronto and the air quality is pretty good! Also helps that the wagon is not full.

Le Modèle O devient l'un de nos moniteurs fixes les plus populaires. Cette commande part chez un client qui utilisera plusieurs appareils pour surveiller la qualité de l'air dans tout un bâtiment.

Model O is becoming one of our most popular fixed air quality monitors. This single order is heading to a customer who will use several units to monitor air quality across an entire building.

Can a VOC Index sensor spot a change in the air? 👀
I cleaned my 3D printer bed with 95% isopropyl alcohol this morning. My Model O’s VOC Index jumped from ~100 to nearly 500.
It’s a relative signal, not a VOC concentration in ppm.

Est-ce qu’un indice de COV réagit aux vapeurs d’alcool? 👀
J’ai nettoyé le plateau de mon imprimante 3D avec de l’alcool isopropylique à 95 %. Résultat : l’indice de mon Model O est passé d’environ 100 à près de 500!
#QualitéDeLAir #COV #Impression3D
So got the Wifi7 Access point, provisioned it, and connected a @Visiblair Model O to it. All works as expected.

1/3 Some IAQ monitor testing is coming soon 🙂
I'm still preparing the ground: setting up monitors, getting everything connected and working out the protocols before the actual testing begins.
I have 15 monitors and sensor evaluation kits in total. Here are some of the monitors I currently have set up and running at home. 🧵

Thanks for asking. ;-) I just posted yesterday a comparison of the Model O and the AirGradient One: visiblair.com/articles/model…
