Makers around the globe are building low-cost devices to monitor the
environment, and with this hands-on guide, so can you. Through succinct
tutorials, illustrations, and clear step-by-step instructions, you’ll
learn how to create gadgets for examining the quality of our atmosphere,
using Arduino and several inexpensive sensors. Detect
harmful gases, dust particles such as smoke and smog, and upper
atmospheric haze—substances and conditions that are often invisible to
your senses. You’ll also discover how to use the scientific method to
help you learn even more from your atmospheric tests. - Get up to speed on Arduino with a quick electronics primer
- Build a tropospheric gas sensor to detect carbon monoxide, LPG, butane, methane, benzene, and many other gases
- Create an LED Photometer to measure how much of the sun’s blue, green, and red light waves are penetrating the atmosphere
- Build an LED sensitivity detector—and discover which light wavelengths each LED in your Photometer is receptive to
- Learn
how measuring light wavelengths lets you determine the amount of water
vapor, ozone, and other substances in the atmosphere
- Upload your data to Cosm and share it with others via the Internet
