About Birdie ®
Birdie® is the cutest, best-reviewed and most iconic air quality monitor in the world.
Now upgraded with more sensors:
- CO2
- Temperature
- Humidity
- Pollen (Google API)
- AQI — Outside Air Quality (Google API)
- Native app + Smart Home Connectivity (Homey + Home Assistant)
How It Works
The analog part:
When air quality drops, Birdie drops. It stays "dead" until you open a window and let some fresh air in. Once the air is clean, Birdie pops back up. Voila!
The Sensors:
Inside hides a suite of Swiss-made Sensirion™ sensors (the "Apple" of sensors) measuring CO2, Humidity, and Temperature with medical-grade precision.
The App:
Birdie Pro now pairs with an intuitive app that makes the invisible even more visible. Track the CO2, temperature, humidity, mold risk, local pollen levels and outside air quality with integrated Google APIs. View graphs with historical data and dive into educational content on indoor climate + customize CO2-threshold.
Smart Home Integrations:
Birdie Pro works with Home Assistant and Homey.

Frequently asked questions
What is Birdie Pro?
Birdie Pro is a smart indoor air-quality monitor shaped like a little yellow bird. It physically "faints" when the air quality in a room deteriorates and stands back up once the room is properly ventilated. It's the upgraded successor to the original Birdie / Canairi monitor.
How does it actually work?
Instead of beeping or flashing, Birdie communicates through movement. When air quality drops, Birdie drops. It stays "dead" until you open a window and let some fresh air in. Once the air is clean, Birdie pops back up. It's a calm, glanceable cue rather than another notification competing for your attention.
Differences between Birdie Pro & Birdie?
The analog "fainting" magic is the same, but the Pro adds far more sensing and a companion app. Birdie Pro now measures CO2, humidity, temperature, mold risk, pollen, and outside air quality, where the predecessor was purely a hardware device.
Do I need the app? Does it work on its own?
No app required for the core experience. Birdie Pro can still monitor CO2 without the app, the fainting behavior works on its own. The app is there if you want deeper insight, detailed metrics, and historical data. That means you need the app if you'd like to track temperature, humidity, calculate mold-risk, check pollen numbers, and outdoor air-quality (AQI) data.
Does it connect to my smart home?
Yes. It supports smart home ecosystems like Home Assistant and Homey, with more integrations planned.
Will Birdie Pro need a subscription?
No. Birdie Pro doesn't require any subscription. The app and all of its features are included with your device at no extra cost. You buy it once and everything works, with no recurring fees or paywalled features. Your history is kept on the device for 30 days and synced to the cloud for free. We simply don't store cloud data for longer than one year.
What does Birdie Pro measure?
CO2, temperature, and humidity onboard, plus calculates mold-risk, pollen, and outdoor air-quality (AQI) data surfaced through the app. Inside is a suite of Swiss-made Sensirion sensors measuring CO2, humidity, and temperature with uncompromising Swiss precision.
Where should I hang my bird?
As a rule of thumb; 1 Birdie should be enough to cover a room up to 100m². We typically recommend to install the bird in the room of your home where you spend most of your time. If you have multiple floors or closed-off rooms (a bedroom) we suggest 1 Birdie each floor/closed-off room. We recommend you to install the bird in a height of 1,5-2,5m.
How do I hang Birdie® on the wall?
Birdie comes with a wall mount that you can put up with either the included screw or the included 3M tape.
What is the expected battery time of Birdie®?
Battery time is up to 1 year with regular usage.
How is it powered? How long does the battery last?
It's fully wireless. It has a rechargeable battery that lasts up to 1 year on a single charge via a standard USB C (included with the product). Charging time is approximately 8 hours.
Lights and sounds?
None — Unlike other air quality monitors, Birdie® will let you know when to ventilate your home without the use of annoying light or sound. Birdie® stands out by using storytelling and intuitive design as nudging mechanisms to encourage the user to take action on their indoor climate.

This is amazing!
"I discovered the product via Kickstarter and have been a fan since day one! I use it in my office and have to say that I used to get Bret regularly in the office and since day one I have been ventilating much mure and it has a huge added value for my health and well-being!!!! Best regards from Germany and keep up the good work!"

Best bird in town
"This little guy actually works. Its sense any change in the air. Love it."
Andrea from CH
Functional meets form.
"You wouldn't think to really care about such a thing, but I noticed that even after months of using it... if we see the bird upside-down... we just open a window. It's something I didn't think we would care about after this amount of time... but we just kind of do it, and I love that."
Pam, US
What a cute and functional concept!!
"We love our canary in a coal mine apparatus! Its one of those cute yet insanely important functional items one very occasionally finds for the home- and must have! Simply opening my window revives my little buddy and often makes me smile in the process."
Viktor, US
Art that works
"Super easy to set up and it works! We set our up and after charging it and mounting it the bird fell down. We opened windows and about 10 minutes later the bird went upright. People have commented how cool it look, going to buy as a gift for a family member as well."

Why a Bird?
Back in the days, mine workers would bring a canary with them in the coal mine, to detect toxic gasses. When the bird fainted, it was time to get out. With a built-in CO2-sensor, Birdie®works exactly the same way - but in your home, office or classroom.
When the air quality is poor the bird will drop, until you open your windows and bring it back to life.

The Indoor Climate Crisis
Did you know that 90% of your life is spent indoors? — Very often in poor air quality, which increases the risk of asthma, headache, allergies and sleep disorders. (Just in the EU, 80 million homes are estimated to have a poor indoor climate.)
So what to do about it? Experts suggest that one of the best solutions is to simply open the windows. Health Authorities worldwide even recommend you to do it 2-3 times a day. Birdie®is a friendly reminder to a keep healthy indoor climate.
