The AirGradient DIY Air Quality Monitor Kits

You can either buy the components yourself and build it on your own, or purchase one of our kits from our online shop. We also have a pre-soldered kit available that is very easy to assemble and get running.

BASIC

Compact air quality monitor with industry grade sensors but without enclosure.

  • AirGradient PCB (Basic)
  • D1 Mini v2/v3 (Micro USB)
  • Senseair S8 CO2 sensor (NDIR)
  • Plantower PMS5003 PM sensor (incl. cable)
  • SHT30 temperature/humidity Sensor
  • OLED display 0.66"
  • Extra female pin headers (20x)
  • 6 months AirGradient data platform (or connect it to your own server, e.g. home assistant)
  • Fully open-source code so you can easily make adjustments

USD 67.00

PRO

The PRO kit includes a professional plastic enclosure especially designed for accurate air quality measurements. It offers a lot of extensability for additional sensors or other things you might want to add.

  • AirGradient Enclosure with Display Window Bottom Right
  • AirGradient PCB (Pro)
  • D1 Mini v4 (USB C)
  • Senseair S8 CO2 sensor (NDIR)
  • Plantower PMS5003 PM sensor (incl. cable)
  • SHT31 temperature/humidity Sensor
  • OLED display 1.3"
  • USB-C cable (2m, 90 degree)
  • Extra female pin headers
  • Screws for PCB, Enclosure and PMS sensor
  • USB-C and JST connector (for PM sensor)
  • PCB has slots for TVOC, pressure or other sensors (sensors not included)
  • 12 months AirGradient data platform (or connect it to your own server, e.g. home assistant)
  • Fully open-source code so you can easily make adjustments

USD 96.00

PRO Pre-Soldered

Identical to the PRO kit but all components pre-soldered, the MCU pre-flashed and can be assembled in five minutes. We do also test all components before shipping to ensure you get an accurate and reliable device.

  • AirGradient Enclosure with Display Window Top Left
  • All components pre-soldered and tested
  • AirGradient PCB (Pro)
  • D1 Mini v4 (USB C)
  • Senseair S8 CO2 sensor (NDIR)
  • Plantower PMS5003 PM sensor (incl. cable)
  • SHT31 temperature/humidity Sensor
  • OLED display 1.3"
  • USB-C cable (2m, 90 degree)
  • Screws for PCB, Enclosure and PMS sensor
  • Pin headers, USB-C and JST connector (for PM sensor) already soldered on
  • PCB has slots for TVOC, pressure or other sensors (sensors not included)
  • 24 months AirGradient data platform (or connect it to your own server, e.g. home assistant)
  • Fully open-source code so you can easily make adjustments

USD 128.00

All kits are open-source and you can easily make adjustments in the code and integrate them into your own systems, e.g. Home Assistant.

The AirGradient Dashboard

Since the AirGradient DIY Pro Kits are fully open-cource you can send the data to any server, i.e. Home Assistant. In case you do not have your own data platform we include access to the AirGradient dashboard - a data platform specifically made for air quality monitoring - for up to two years.

Real-Time Dashboard

The powerful dashboard lets you immediately see the air quality and environmental status of multiple locations. Built for speed and scale.

Alerts

You can set up specific alerts and are notified automatically if air quality is exceeds your defined ranges.

Historical Data

The air quality data is saved in 5 minute intervals and all data can be easily exported for further analysis.

Reports

Get powerful daily and weekly reports detailing the air quality of each location, providing you with a clear, concise summaries at a glance.

“We put all our experience and knoweldge from developing our high quality air quality monitors into this open source DIY Kit. It is also available as pre-soldered version that you can literally built in minutes.”

Feedback from Kit Users

We built 20 DIY sensors to monitor the air quality and particularly CO2 in our nursery. The system works extremely well and the alerts from the AirGradient dashboard platform are very helpful.

Tim Davis

Achim from AirGradient was extremely helpful to sort out a small issue I had during the building of the sensor. I compared the data of the AirGradient DIY sensor with two other air quality monitors that cost much more and the data from the Airgradient seems to be very accurate.

Ethan Flick

I was part of the pilot. The build was very easy and the plastic enclosure of the Pro version very nice. I first connected it to Home Assistant on my Pi but then found the dedicated data platform from AirGradient a much better fit.

John Wagen

My son has asthma. And I am trying to pass on my love of DYI electronics to him. So I thought we’d build it together to help him track if conditions might be of concern to his health. I’m not sure if Luxembourg’s air is bad, but I wouldn’t call Central Europe exactly good. And with our own sensor we can also track traffic influences etc.

Indoor levels of carbon dioxide could be clouding our thinking and may even pose a wider danger to human health, researchers say.

Why we care about Air Quality

AirGradient started as a volunteer project to help a school in Northern Thailand monitor the air quality in classrooms during the highly polluted burning season. From the beginning, we have worked with students and educators to building hardware to increase awareness in the area of air quality, to understand the health impacts of pollutants, and to empower the positive changes that can be made to reduce air pollution.

The experience and expertise that we gained designing and manufacturing our professional AirGradient ONE RESET Air Accredited Monitor has been put into our open-source / open-hardware air quality build instructions and kits.

The industry-grade sensor modules used in the DIY Kits are the same modules found in pre-built monitors costing hundreds of dollars. As a result, you get highly accurate data quality, essential to having a reliable understanding of the air around you.

Advantages ordering from us

Trusted Components

We buy large quantities from trusted suppliers that we work with for quite some time and do quality check on the incoming components. Especially for the PM2.5 sensor, there are often sensors online available that are less accurate than they should be. We test all PM2,5 sensors of the kits in-house and only send them in the kits if they pass our own quality criterias.

All in One Package

When you order parts from different suppliers from China, often some parts take very long to arrive (sometimes even months). With the kits you can ensure you get them delivered all at the same time. Our shipment times to Europe and North America are typically 2-3 weeks.

Kit includes Data Platform

Our kits come with a special DIY Premium Plan for our data platform. So in case you do not want to hook it up to your own data platform, you can use ours for a certain time for free.

Special webinars for large groups and schools

If you have a group of people wanting to build the sensor, e.g. a group of students or a maker space, we are available for a dedicated webinar to explain the build and answer any potential questions. Please contact us for details.
