Chapter 12
Building a Home Sensing Station
In This Chapter
Building custom temperature and light sensors
Building a homemade Arduino shield
Programming your sensing station
Posting your sensor data to the Internet
Lots of people have been using their Arduinos to wire things up to the Internet, so much so that folks are starting to talk about an “Internet-of-Things.” There are Internet-enabled lamps, weather stations, and even whole buildings that are wired up to post their data online. Your Arduino has a pretty powerful little microcontroller on board, and it can easily handle the tasks of collecting environmental data and sending it to the Internet.
In this chapter, you create a home sensing station that collects light and temperature data and posts it online. Your sensor station uses an Arduino Ethernet shield so that after your station is built, you don’t have to leave a computer running. It just talks directly to the Internet over your home router. You also find out how to build temperature and light sensor probes and a homemade Arduino shield to connect them to your Arduino. ...
