Today we published the first in a two part wireless sensor project series, wireless temperature sensor:

Next week's project will be a wireless door contact.
RF communications can be complex so we've chosen to preconfigure our wireless devices and sell them through our store ready to be used with no configuration and any need for programming or end-user configuration. When I say plug them in and go I mean it, they transfer serial data transparently without requiring any initial config.
The RF units operate in the ISM bands (868 to 915 MHz) and that means it has a greater range than Bluetooth, WiFi or Zigbee sytle 2.4 GHz units that sport the same footprint. That means it goes through more walls and reaches further. The devices have been tested to send data over more than 3 KM using the standard supplied whip antennas out side.
Makes use of Texas Instruments’ CC1110, a low-power System-on-Chip, which sports a micro-controller unit (MCU), memory, a sub-1GHz transceiver, and an encryption engine.
Another useful feature is their ability to sleep while there is no activity and conserve battery power.
