It is based on the Xbee module from MaxStream. The module can communicate up to 100 feet indoors or 300 feet outdoors (with line-of-sight). It can be used as a serial\/USB replacement or you can put it into a command mode and configure it for a variety of broadcast and mesh networking options. The shields break out each of the Xbee's pins to a through-hole solder pad. It also provides female pin headers for use of digital pins 2 to 7 and the analog inputs, which are covered by the shield (digital pins 8 to 13 are not obstructed by the shield, so you can use the headers on the board itself). The Xbee shield was created in collaboration with Libelium, who developed it for use in their SquidBee motes (used for creating sensor networks).\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eNetworking:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Arduino \u003cspan class=\"wikiword\"\u003eXBee\u003c\/span\u003e shield can be used with different \u003cspan class=\"wikiword\"\u003eXBee\u003c\/span\u003e modules.

Show your card within the reading distance and the card number is thrown at the output. This is a great little RFID Reader Module from Innovations, simillar to the ID models. If you need an inexpensive way to get started with RFID, this is a great little module. Just power the module, and it will read any RFID card within range.

Handy for when you need to measure something far away, or in wet conditions. While the sensor is good up to 125°C the cable is jacketed in PVC so we suggest keeping it under 100°C. Because they are digital, you don't get any signal degradation even over long distances! These 1-wire digital temperature sensors are fairly precise (±0.5°C over much of the range) and can give up to 12 bits of precision from the onboard digital-to-analogue converter. They work great with any microcontroller using a single digital pin, and you can even connect multiple ones to the same pin, each one has a unique 64-bit ID burned in at the factory to differentiate them.
