Using cost-effective Zigbee

What is a sensor?
A device that receives and responds to a stimulus or signal. Sensors measure real-world conditions, such as heat or light, and then convert this condition into an analogue or digital representation.

What is ZigBee?
A wireless network that can be used for home, building and industrial control with a maximum speed of 250Kbps at 2.4GHz. It is designed for low power so that batteries can last for months, even years. The typical transmission range is around 50m.

What is wireless communication?
Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires." The distances involved may be short (a few metres as in television remote control using infrared light) or long (thousands or millions of kilometres for radio communications).
