AirGradient: DIY Air Quality Monitoring with Open-Source Hardware & Firmware
Hi, founder of AirGradient here. Great to see that somebody submitted our open source DIY sensor instructions here!As last time I am more than happy to send free PCBs to anybody who wants to build this sensor. It makes the build much easier as you don't have a lot of cables to handle. You just need to paypal me the postage fees.If you like to get some, please press the orange button on the website and send me a message.
