Anyone know a place in Canada or USA where I can get wind sensors like this (ultrasonic anemometer) ?

🕷️ One of my outdoor air quality monitors read way too low today…
A spider web was the culprit! 🫣
A quick blast of air fixed it.
The Model X2 has removable mesh to block bugs & make cleaning easy—without hurting airflow.

Followers, need your help. I'm attending a trade show in September to promote @VisiblAir products and need to make a banner that will be in front of the booth table and on the backdrop. This is pretty much the best I can do 😂
Any comments, suggestions, which one do you prefer ?

😮 Huge spike in particulate matter detected earlier today in the Montréal South Shore area!

Our Dev Model X2 sensor showed a dramatic rise in PM1.0, PM2.5, and PM10 starting around 3PM — classic signature of smoke-laden air. 🌫️

😮 Grosse montée des particules fines détectée aujourd’hui sur la Rive-Sud de Montréal!

Notre capteur Dev Model X2 a enregistré une hausse fulgurante des PM1.0, PM2.5 et PM10 vers 15h — typique d’un air enfumé. 🌫️

🚨 Model X2 Update! 🚨
The SEN66 sensor was a bit too chill about wildfire smoke. 😬
We ran tests. We saw the issue.
The new Model X2 will use SEN55 + SCD30 for better outdoor PM.
