Airgradient builds equipment for monitoring air quality indoors and outdoors, with the aim of giving people accurate readings they can rely on. The monitors are developed along open-source and open-hardware lines, so users are free to build, customize and maintain their own devices. Transparency and affordability guide the company, which offers both kits for people who assemble a monitor themselves and pre-built units that arrive ready to use.
The range covers key pollutants including PM2.5, CO2 and volatile organic compounds. Monitors like these help owners see how ventilation and daily activity change the air in a room, and how conditions differ from one location to another. Airgradient also works with educational institutions to sharpen accuracy and encourage environmental awareness, which makes the products a good fit for schools and community projects. The company is based in Chiang Mai, Thailand.
