Great Start with an excellent starter kit
For Wireless Sensor Starter Kit
This kit has everything you need to get started in the area of wireless sensors. The boards are very professional, and the cases finish it off perfectly. With this kit, it's really easy to learn about wireless communication using 433mhz, maximizing battery life, and combining sensor elements. Example sketches are also available, so it is possible to go into the finer details of how it all works.
I'd recommend it for both the experimenter wanting to learn, or the home automation enthusiast wanting a cool product!
