Book Description

Around the globe, DIYers are building an infrastructure out of low cost sensors, cheap computers, and cloud-based data sharing. One of the most important environmental conditions to monitor is the quality of the atmosphere. Atmospheric Monitoring With Arduino shows you how to create your own gadgets to measure what's inside every breath you take; the kind and size of dust particles from smoke to smog, how much haze is in the upper atmosphere, the transparency of the night sky, and more!

You'll also learn how to share your data with people across your community, your nation, and the world, and how to build rugged enclosures to protect your gadgets in the field.
