Internet of Things sandpit

This is a sandpit for playing with the Internet of Things. It is used to help me play with and understand the IoT by writing and playing with simple applications. I am familiar with the entry level Arduino and will be exploring the uses of this and similar devices over the next year, as well as the more powerful ARM-based devices. I am starting with simple gadgets such as remote temperature and gas concentration monitoring. I shall probably use a small part of this page for non-commercial experimental data collection, communication and control. In particular, I expect to create a small device which monitors temperature and humidity and occasionally uploads this via WiFi to this site, thereby enabling me to access the data it has acquired.
