Crowdfunding for Airgeek M1 starts summer 2025!

Airgeek is almost ready to go, with the final round of improvements now in progress.
We're crowdfunding soon, and we'd love for you to join us.

Thanks for your interest! You've been subscribed.

We're very sorry, but we couldn't subscribe you:

  • Please double-check that there are no typos in the e-mail address you entered.
  • Please check that the domain has a correctly configured MX record.

You'll receive a single email from us when the crowdfunding campaign starts.
We will then remove your address from our system unless you opt in explicitly.

The Hardware

The sensor set, radio and control logic of Airgeek M1 is exactly the same as Airgeek A1. Even the board is the same—we just omitted the batteries and used a smaller NFC antenna. This makes the module extremely small and lightweight, making it easy to incorporate it into your own design.

Airgeek M1

  1. Matter over Thread + Zigbee radio module by STMicro.

  2. PM1, PM2.5 and PM10 sensor made in Germany.

  3. Low-power CO2 sensor made in Sweden.

  4. Atmospheric pressure sensor made in Germany. It allows for precise pressure compensation of all readings.

  5. NO2 and CO sensors made in the USA.

    Note: The prototype shown uses a CO sensor made in Japan. The NO2 sensor is stacked above and is not shown.

  6. Temperature/relative humidity sensor made in Switzerland. We're using one of the most accurate sensors for temperature and humidity available.

  7. Single high-quality AA battery (optional 2nd battery).

  8. NFC chip and antenna used with the Airgeek app.

Breathe Better with the Airgeek App

Airgeek M1 uses the same Android and iOS app as Airgeek A1 and the same NFC interface. With a suitable power supply, the M1 can be used as a data logger out of the box. The Airgeek app, which is completely and forever free, is here to help you improve your indoor air quality. It works like this:

  1. Collect data. Airgeek measures all of the aforementioned air quality parameters in regular intervals. It stores data in memory and produces long-term statistics.

  2. Analyze. The Airgeek app downloads and analyzes the data via NFC. If any parameter falls outside of the healthy range, it suggests how to keep it in line.

  3. Change your behavior. Follow the app's advice. Often, a small change is all that's needed to make a big improvement.

  4. Did it work? In a week or two, the effect should be clearly visible. Validation is an important step in every scientific experiment.

  5. Keep at it. Check your device every now and then to understand how the quality of your air changes with time and to keep it in check.

Connectivity & smart home integration

Airgeek M1 supports the two most popular[1] IoT connectivity standards for home use: Matter over Thread, and Zigbee[2]. It will work with Apple Home, Google Home, HomeAssistant and other Smart Home apps and hubs. This allows you to use precise measurements to control your Heating, Ventilation and Air Conditioning (HVAC) equipment.

  1. Based on the results of a survey we did among the participants of embedded world 25 (n = 81). The connectivity preferences were: Matter over Thread (25 %), Zigbee (23 %), NFC (21 %), data display only (12 %), other (19 %).

  2. Work on Zigbee and Matter is now in progress. Our devices will be certified for Matter over Thread and Zigbee by the CSA.

Extremely power efficient platform

Airgeek A1, our complete air quality monitor for home and work use, is a battery-operated device. A lot of effort went into making it as power efficient as possible.

Since the M1 shares the electronics of the A1, it too is extremely power efficient, consuming just 180 μA at 3.3 V on average in the default configuration. This means it can be used in both battery-powered and mains-powered applications easily.

The built-in boost converter is able to start from 0.8 V, making it possible to run the module on a single AA or AAA battery of virtually any chemistry.

Revolutionary design with no moving parts

Airgeek is the world's first complete air quality monitor with no moving parts. All other devices currently on the market utilize a fan-based PMX sensor.

Airgeek A1 integration of the BMV080 sensor

Airgeek instead relies on the BMV080, a revolutionary sensor developed by Bosch Sensortec which counts particles flowing freely in the ambient air—basically a tiny dust radar. It uses a safe, invisible infrared laser and collects laser backscatter from the particles as they fly by.

Our philosophy

We took the business practices we don't like and decided against them:

  1. No subscriptions. We make money by building and selling hardware. We won't force-feed you yet another subscription you don't need. The device and the data it collects are yours and yours only.

  2. We don't compromise on the hardware. We take no joy in building products that are cheap and subpar. We wanted to build the best air quality monitor possible and we think we did.

  3. You have the right to remain offline. All online features and integrations are completely optional. NFC is used for communication with the Airgeek app, allowing the radio to be disabled permanently.

  4. We don't sell you out. If anything gets stored on our servers, it's encrypted so that even we can't read it. Our apps have no telemetry. We don't track you and we don't sell your data.

  5. We aim to remain a small and efficient company. That way, we don't have to squeeze every last bit of revenue from our customers, and our interests can remain aligned with yours.
