**the battery will usually last for 6+ months before it needs to be recharged with the following USB-C cable.

That’s it. You’re all good to go

That’s kind of all you need to know about Birdie. It’s as simple as it looks.

Still hungry for more details?

You really don’t have to keep on reading, but we won’t stop you from geeking out on technical information:

How does it work?

Birdie® is detecting the CO2-level in your room every 10 min. If the CO2-level exceeds 1000ppm, Birdie® will drop down.

When Birdie® is hanging down it detects the CO2-level every 5 min. the first 30 min. and then every 10 min. after that.

If the CO2-level is above 1000ppm Birdie will stay down, until next detection.If the CO2-level goes below 800ppm, Birdie® will automatically pop-up into upright position. 

After Birdie® repositions to upright it will enter a cool-down period of 2 hours, in order to save power and because it’s rare that the CO2-level will exceed 1000ppm within 2 hours after ventilation.

If you wish to get an exact detection of the current CO2-level, simply just lift and replace Birdie® on the wall-mount. - this will reset Birdie® and detect the CO2-level immediately.

How do I charge it?

Birdie® is battery-driven and will last +6 months on a full charge. If you don’t want to think about charging it, you can install it with the USB-C plugged-in permanently.

The LED-lamp on the backside of the bird is only an indicator for battery-status. Red = Charging. Green = Fully charged.

Where should I place the bird?

As a rule of thumb one Birdie® should be able to cover a room up to 150m². We typically recommend to install the bird in the room of your home where you spend most of your time. We recommend you to install the bird in a height of 1,5-2,5m.
