Birdie: Indoor air quality made simple

November 6, 2023

Birdie® is an intuitive indoor air quality monitor using a CO2-Sensor to help you keep a healthy indoor climate. Back in the day, mine workers used to bring a canary with them in the coal mine, to detect toxic air. 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 air quality is poor, Birdie® will drop down until you open your windows and bring it back to life. Simple as that.

Indoor air quality made simple


90% of our life is spent indoors - often in poor air quality increasing the risk of asthma, headaches, fatigue, and sleep disorders. Ventilating regularly will improve your well-being, sleep, and overall health. Birdie stands out by using storytelling and gamification as nudging mechanisms to encourage the user to ventilate their home/school/office in order to improve health and well-being.


Birdie is the world's first and only indoor air monitor not using light, sound, display,or notifications to activate the user to take action on the problem. This might seem like a simple innovation, but it’s a breakthrough in the way that we communicate with the products/services in our everyday life. The company believes that this design approach is innovative in its core and can lead the industry forward towards more engaging, efficient, and inspiring solutions.
