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!)
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. 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.
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.
More app users per sensor
Q: Can more people in my family see the sensor data?
A: No, right now we only support a single user connecting to a sensor and viewing data from it. We plan to improve this and let more people see sensor data.
Access to my own sensor data
Q: Can I download my own sensor data?
Q: Can I see data from other sensors?
Q: Can I see sensor data in a map?
A: All of these are on our to-do list!
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
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.
What do the colours in the pm2.5 graph mean?
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.|

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.)
We are now calibrating our pollen calculations and will soon add colour coding in the graph, to indicate levels from low to very high.
We are also 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.
