Architecture: ZC - ZR - ZED● �The ZigBee coordinator (ZC) initiates a personal area network,

allow other devices to join and control the information with security keys.

● �The ZigBee Router (ZR) transfers the messages between components.

● �The ZigBee End Devices (ZED) communicates info (here temperature) to router or coordinator and can receive instructions.
