Sensor installation

Q: My sensor shows no light.
A: Check if the power adapter and USB-cable are working properly.

Q: There is no power adapter for my sensor.
A: You need to use your own power adapter – that probably is meant for indoor use. There is a slight risk that the adapter will stop working, depending on exposure to wind and weather. We are working on a better solution, one that is designed for outdoor use and that does not cost a small fortune. (Any smart tips will be appreciated!)

Wifi connection

Q: I get my neighbour’s address and house number when I connect to wifi.
A: While connecting to your home wifi, your neighbour’s address may show up for your sensor. This is a general challenge with such connections and we are working on improvements to let you register the correct address. With the current solution it is still your data from your sensor that are registered and that you see in the app.

Q: What happens during and after a power break on the wifi network?
A: With a power break on the wifi network, the sensor will stop sending data and you’ll get an alert in the app. When the power is restored, the sensor will return to its last connected wifi network and will continue to send sensor data as normal.

Q: Can I change the wifi network connected to the sensor after the first onboarding?
A: If you want to change the wifi network for your sensor, you’ll need to repeat the onboarding procedure.

Q: Can I move the sensor between different locations?
A: If the sensor is moved between different locations, you’ll need to reconnect to a wifi network. Please also let us know, so that we can update the location in our systems and register data to the correct place.

Sensor onboarding

Q: How do I install and start using my airminer 2.0?
A: Please follow our installation guide. If you still need help, do not hesitate to contact us on support@airmine.ai.

Q: The sensor data I see in the app are from before I connected my sensor and they are not updated.
A: If you during installation of the sensor go directly to scanning the QR-code on the backside of the sensor, your sensor will not be properly connected. (If you do this, you’ll just see testdata, not your measurements.) You need to first connect to your home wifi network, then you can scan the QR-code on the back of the sensor.

Mounting the sensor

Q: Can the sensor be installed indoors?
A: airminer 2.0 is designed for outdoor use. If you want to set up your sensor indoors, please let us know so that we can provide you with correct data from your sensor.

Q: How protected does the sensor need to be outdoors?
A: The sensor should be protected from rain/snow and wind. 

Q: How do I tell if the sensor is oriented correctly?
A: The rounded part of the sensor is the top. The flat part, where there is an air intake for the fan and a small LED light is at the bottom. It is very important that the sensor is mounted correctly

Q: What happens if I unplug the power for my sensor?
A: Your sensor will go offline and you’ll get an alert in the app. When you plug the sensor back to power again, your sensor should come online, you don’t have to do anything.

More app users per sensor

Q: Can more people in my family see the sensor data?
A: Yes, you can invite friends or family members to see your sensor data. You press the “Add a family member”-button in the sensor screen in the Airmine app, and let your friend or family member scan the QR-code that is displayed in your app. Your friend/family member needs to first have downloaded the Airmine app on their phone.

Access to my own sensor data

Q: Can I download my own sensor data?
A: It is on our to-do list!

What is displayed in the pm2.5 graph?

The histogram for pm2.5 shows the concentration of pm2.5 particles in the air around your sensor.

Sensor -pm2.5 graph in app

What do the colours in the pm2.5 graph mean?

Level PM2.5
μg/m3, 24 hour average
What does it mean to you?
Good 0-12 Safe and healthy air. Open windows, enjoy outdoor activities.
Moderate 13-35 Moderate pollution.  Can affect sensitive people. Sensitive people should consider reducing hard physical activities outside
Unhealthy for sensitive 36-55 Unhealthy air for sensitive people. Sensitive pople (asthmatic, children, elderly, people with heart diseases and respiratory diseases) should limit physical activities.
Unhealthy 56-150 Unhealthy air!  Sensitive people should avoid physical activities. Everyone else should limit physical activities. 
Very unhealthy 151-250 Very unhealthy air!  Sensitive people should avoid outdoors, everyone else should limit outdoor time.
Hazardous 251- 500 Dangerous air!  Remain indoors.

We are using the US Index for pm2.5 levels. There are quite a few indices around, for an overview, please see Wikipedia – Air Quality Index.

What is displayed in the Total Pollen graph?

The histogram for Total Pollen shows the concentration of all pollen particles in the air in the area where the sensor is located. The values for pollen are calculated from sensor measurements using machine learning (we measure particles, including pollen, but we need to use mathematical models and satellite data to estimate how much of the particles that actually are pollen.)

Coming up

We are regularly improving our pollen models to improve precision per sensor. We are also estimating levels per pollen type, grass pollen is on top of our list.

WHO tightens air quality guidelines

WHO releases stricter air quality guidelines to protect human health. The new standard for fine particles (PM2.5) is halved, stressing that exposure to PM2.5 is a major health risk.

The accidental badger detector

PM2.5 levels peaked late at night and early mornings at our sensor test site and we struggled to find out why. Turns out the answer had fur and four legs.

We’re measuring pollen!

We are running our airminer 2.0 sensors to calculate local pollen levels. As expected, pollen levels vary with temperature and precipitation, but we also see significant variations through the day.

When to expect birch pollen in Norway?

Hazel and alder is flowering in Southern Norway, but the key allergen to many of us is birch. When can we expect the birch pollen season to start?

Spring in Europe – alder, hazel and birch pollen

We are heading into warmer and lighter days in Europe, lockdowns or not. And no surprise, the pollen is faithfully here.
