Altos CO2 sensor

SpecificationsCO2 sensor (measurement range: 400-5000 ppm) Humidity sensor (optional) Powering: rechargeable battery Battery life: ~6 months on a single charge Recommended operating temperature: 0…50 Connection type: Bluetooth Indication: LCDUser guideTurn on your AltosPress and hold the button until all display segments turn on and blink once. After that, the display starts indicating the current Brain Fuel level.Trouble turning on?If your Altos doesn’t turn on, make sure it is charged: connect it to the power outlet by the USB Type-C cable and retry (see Charge Altos for details).Using AltosAltos’ display shows how much Brain Fuel* is in the air around you. The fewer of nine display segments are on, the less Brain Fuel is in the air.* Brain Fuel index shows how much helpful for your productivity air is in your environment. Brain Fuel level changes in the reverse proportion to the CO2 concentration: as CO2 rises, the Brain Fuel index falls.

When all nine segments are lit, you’re all set to get your work done ­ the air composition is ideal for intellectual work. If the display shows only one segment, the CO2 concentration in the air around you is critically high.To get precise info about how the air helps your productivity, provide that nothing obstructs the air inlet to the Altos air intake.Here’s a correlation of Brain Fuel index and CO2 concentration level:

CO2, ppm

Less than 449


450 – 499


500 – 599



Air composition optimal for productive work. Keep it up!

Connect to the appTo track how the Brain Fuel index has been changing over time and get notified of changes in air composition, get the Altos app and connect it to your Altos.You will need an Internet connection to install the Altos app and Bluetooth to connect your Altos with your mobile device.Install the Altos app on your mobile device. Search for Altos in Google Play or App Store or scan the QR code.Open the app and follow its guidance to connect your Altos.Trouble pairing?If Altos doesn’t pair with your phone or tablet:make sure the Bluetooth is enabled for the Altos app, hold the Altos button for three seconds and try pairing one more time, try restarting Altos.Enable push notificationsPush notifications warn you when the air around you lacks Brain Fuel and give a timely prompt to let some air in. When the air composition goes back to normal, you will also be notified on your phone.To get notified of significant changes in air composition, give the Altos app permission to send you push notifications. Once you pair your Altos and the phone, you will be prompted to enable notifications and location services.

If you skip these steps on Altos set up, you can change notifications and location services preferences later in the app settings.

Usage recommendationsOn a single battery charge, Altos works for approximately six months. Charge Altos timely to stay informed of the air composition changes.Recommended operating temperature range is 0…50. At lower temperatures, the device’s sensors might perform incorrectly. It might take some time to get back to normal work if the device stays in the cold for a while and then is brought to a warm place.To ensure a stable Bluetooth connection, the distance between your phone and your Altos should be less than 10 meters.Troubleshooting
