Klimerko measurement device

What is a Klimerko device

Klimerko is an open-source DIY air quality monitoring device designed to measure outdoor air pollution. Every 15 minutes, it records the concentration of PM2.5, PM10, and PM1 suspended particles, classified as air pollutants, while also measuring temperature, air humidity, and air pressure.

Join the largest citizen initiative for monitoring air pollution in Southeast Europe. Klimerko's open-source hardware and software make it accessible to anyone. You can easily assemble and install it on your terrace, contributing to the growing network.

Klimerko: Measure air quality in your community

Klimerko is an open standalone device for monitoring air quality, designed to measure outdoor air pollution. Every 15 minutes, it sends data on the concentration levels of PM2.5, PM10, and PM1 particulate matter (air pollutants), as well as air temperature, humidity, and pressure.

Join the largest citizen initiative for monitoring air pollution in the Western Balkans. Klimerko is accessible to everyone thanks to its open hardware and software. You can easily assemble it and set it up on your balcony or window, contributing to the growing network of data.

Monitoring air quality in your community can help you protect your health and the health of your loved ones. It can also help you identify sources of pollution and advocate for change.

Get your own Klimerko

Klimerko is a small-batch, made-to-order air quality monitoring device, passionately crafted by a team on a mission to democratise air pollution data.

Here is how you can get your own Klimerko:

  1. Build your own Klimerko. If you're a tech enthusiast, detailed instructions and technical support are available on our GitHub page. to help you build your own Klimerko.
  2. Buy a pre-built Klimerko device. If you're not tech-savvy but still want your own Klimerko, you can buy a pre-built device that's ready for use. Pre-built devices are shipped from Belgrade, Serbia and are typically available within 7 to 21 days.
  3. Arrange a workshop with us. Learn how to build your own Klimerko in a workshop, typically on weekends and for around 3 hours. The fee includes all necessary materials and components.
  4. Apply for a Klimerko initiative. Occasionally, we create projects and announce open invitations for interested citizens to apply and receive a Klimerko device for their use.

Order your Klimerko device today and join the movement to track and improve air quality in your community.

Klimerko Pro: Integrated solution for your projects

Klimersko Pro is the next generation of our measuring devices designed for legal entities that want to measure air quality on a larger scale.

The Pro device, in addition to measuring PM1, PM2.5, and PM10 concentrations, also measures sulfur dioxide (SO₂) and nitrogen dioxide (NO₂). The calibration of this device's sensors was performed by the Institute of Nuclear Sciences "Vinča".

Unlike the regular Klimersko designated for individuals, Klimersko Pro is a complete solution, tailored for easy setup across multiple locations, making it more suitable for projects requiring over 30 stations. It comes prebuilt, with a customized PCB board for easy assembly without soldering, a USB-C connector, and a redesigned casing for easier maintenance. For detailed technical specifications, visit our Klimersko Pro GitHub page, and if you are interested in deploying a project using Klimersko Pro measuring devices, contact us via email.

Reach out for collaboration

In 2021, 135 Klimerko Pro devices were installed in 45 schools, contributing to STEM learning initiatives. Learn more about the project (in Serbian) at decazavazduh.rs.
