Make: Getting Started with Sensors - PDF
To build electronic projects that can interpret and react to the physical world, you need to build circuits based on sensors
Make: Getting Started with Sensors: Measure the World with Electronics, Arduino, and Raspberry Pi. To build electronic projects that can sense the physical world, you need to build circuits based around sensors: electronic components that react to physical phenomena by sending an electrical signal. Even with only basic electronic components, you can build useful and educational sensor projects.
Incorporating an Arduino or Raspberry Pi into your project allows you to build sophisticated projects that can react in interesting ways with their surroundings and even connect to the Internet. This book starts by teaching you the basic electronic circuits to read and react to a sensor. It goes on to show how to use Arduino to develop sensor systems, and wraps up by teaching you how to build sensor projects with the Linux-powered Raspberry Pi.
