Moving sensors for dynamic air quality measurement

‘[…] To put in context the indoor living spaces, […] users need to look at the two sides of the coin in order to take the right action. What’s the point in opening the windows if the outdoor air is also polluted right?‘ – BreezoMeter With this blog post, I want to look with you…

Conveniently keep track of your exercises

Fitness and exercising is more important than ever. Phones and fitness tracker are supporting the user in monitoring their health – and some are even counting the push-ups or sit-ups. Apps are using the proximity sensor in your phone to count your push-ups – some require you to touch the screen with your nose, which…

When your fitness tracker is not honest with you…

Summary: Fitness trackers can be up to 30% off in distance and calorie estimation In both fields, mainly GPS causes this inaccuracy Barometric pressure sensors are able to compensate GPS measurement errors A fusion of accelerometer, barometric pressure sensor & GPS would be highly beneficial Ever wondered, how accurate your fitness tracker really is? How…

GPS vs Barometric Pressure Sensor altitude tracking

Summary: GPS signals cannot always be obtained (especially indoors) Altitude can therefore not be measured, which results in inaccurate calorie expenditure estimations Barometric Pressure Sensors measure atmospheric air pressure to determine the current vertical position Accelerometer could compensate measurement errors within pressure sensor readings A combination of GPS, pressure sensors & accelerometer would be ideal…

InCar Air Quality – PM2.5 & VOCs

Long posts need short summaries: Indoor air can be up to 5x more polluted than outdoor air (EPA, 2017) Filtration systems are a great solution to prevent outdoor pollutants from entering the car InCar Air Quality can still be bad due to VOCs developing inside the car MEMS & air purifiers can be a solution…

Solutions for IAQ monitoring – don’t you worry ’bout a thing

…although, I am not sure if Stevie Wonder was thinking of indoor air quality, when he wrote that song. I found some consumer products, which take care of your indoor environment. Now, most of the devices on the market are passive – meaning, those are basically monitoring your indoor air quality, and tell you the…

Solutions for IAQ monitoring – observe and take action

Recently, I talked a lot about the importance of indoor air quality and why it is so important to keep an eye on it. If you didn’t read it yet, feel free to take a look at them (IAQ & VOC vs CO2). Today, I want to show you, what you can actually do about…

Our buildings are making us sick

Recently, a report on buildings and their effect on our health was published by the Health and Environment Alliance, short ‘HEAL’. In this blog post I summarized some important facts researched by HEAL to give you a short overview. The report is very interesting and contains a lot more information than I included here. If…

Take action – Take care of your health

We started counting our steps & floors, calculating our daily burned calories, measuring our heart rate constantly. Some devices even allow us to measure our blood pressure – all to monitor and take care of our health. But what about breathing? According to EPA, we are inhaling up to 23,000 times a day and as…

Use Cases – Barometric Pressure Sensor

This blog posts bundles all the use cases already stressed in a previous blog post. If you want to know more about the barometric pressure sensor in general, then check out this post. Instead, if you want to take a short-cut to the use cases, below you’ll find the links to several useful applications a…
