Environmental agencies
Continuous outdoor air monitoring for municipalities, researchers, and public health teams.
Patented Particle Intelligence
Real-time portable particle identification for pollen, smoke, dust, and more.
Pollen Sense combines AI, optics, and environmental science to deliver physical measurements instead of rough guesses, powering sensors, licensed datasets, and the Pollen Wise app.
Meet the APS400
From sensing hardware to AI-enabled identification.
The APS400 images and identifies over 98% of collected airborne particles, recognizes particles as small as 0.3 microns and up to 158 microns in real time, and adapts collection based on particle load.

ExploreWhat Better Data Enables
From real-world hotspots to better public-facing products.
The homepage closes by reinforcing the practical outcomes of better sensing infrastructure.
Story 01
What is actually in the air?
From pollen to mold, smoke, and dust, Pollen Sense shifts teams from rough estimates to real physical measurements.
Story 02
How do local conditions change hour to hour?
Pollen Wise and partner products can surface sharper peaks, cleaner lows, and neighborhood-scale signal changes.
Story 03
Why does better infrastructure matter?
Reliable sensing, automated classification, and dense monitoring unlock better forecasting and better decisions.
Story 04
Deep tech, built for real-world use
The APS400 is designed for field deployment, long monitoring windows, and scaling across networks.
Deep Tech, Real World
From estimated forecasts to actual on-the-ground measurements.
Pollen Sense implements technology from aerospace, AI, robotics, and computer vision in a space that was long overlooked by innovation: airborne environmental monitoring.
The APS400 and its downstream data products are built to solve operational problems for allergy care, research, public health, and consumer decision-making.

Incoming: Branches, Revisions, and Layers
Pollen Sense has grown a lot over the last few years! As we approach our 100 millionth frame, wrangling all of the frames and tags has evolved (stay tuned for exciting updates on that 100 millionth frame!). This project has been months in the process, codenamed LIMB.

LLMs vs CNNs: Why Physical AI Starts With Data Infrastructure
When we say “AI” at Pollen Sense, most people assume we mean LLMs. We don’t. When people hear that Pollen Sense is building AI data infrastructure, the default assumption is usually large language models, chatbots, text generation, or conversational AI. That’s understandable given the moment we’re in. But it’s not what we mean when we say AI. At Pollen Sense, AI data infrastructure means Physical AI, machine learning systems that directly observe the real world, classify physical signals in real time, and convert them into structured, trustworthy data that other systems can reason on.

Winter is Here and Pollen is Not!
As temperatures drop, many of our users wonder why the app seems unusually calm. You might scroll and see a few 0’s listed under each category. Don’t worry: seeing low or zero pollen levels during the late fall and through the winter months is completely normal. Winter is the quietest part of the pollen year, and most plants simply are not releasing pollen this time of year.

Five Things to do NOW to Own Your Seasonal Allergies
When the plants of the world have ganged up against you and you are attacked by pollen and mold, it's nice to know that fighting -or retreating- can reduce the severity your allergy symptoms. Allergen load (the number of allergenic particles you're exposed to in a certain amount of time) can be reduced by trying these five tips:
