A buzz-phrase that you may be hearing recently is "The Internet of Things". This phrase summarizes a movement that has been happening for several years – connecting and monitoring things via the web – things like sensors and controllers. The Internet of Things will become very useful when this patched together network operates on your behalf – presenting data to you via the web as necessary and controlling systems in the background.
The data that you would receive from a sensor are strings. Perl's powerful string operations allow Perl to be a perfect language to process sensor feedback and distribute to data stores. The host of CPAN drop-in modules will allow you to connect hardware to web services enabling rapid idea prototyping for projects that link the real world to the virtual world. Imagine this application without Perl: You can track your cell phone via Google Latitude then automatically turn on your air conditioner when you get close to your home.
The object of this talk is to discuss Perl's role in the emergence of the Internet of Things and how you can get started creating applications.
