ZIGBEE

 

ZigBee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks. The standard takes full advantage of the IEEE 802.15.4 physical radio specification and operates in unlicensed bands worldwide at the following frequencies: 2.400–2.484 GHz, 902-928 MHz and 868.0–868.6 MHz.

The power levels (down from 5v to 3.3v) to power the zigbee module.

The communication lines (TX, RX, DIN and DOUT) to the appropriate voltages.

The Zigbee module acts as both transmitter and receiver. The Rx and Tx pins of ZIGBEE are connected to Tx and Rx of 8051 microcontroller respectively. The data’s from microcontroller is serially transmitted to Zigbee module via UART port. Then Zigbee transmits the data to another Zigbee. The data’s from Zigbee transmitted from Dout pin. The Zigbee from other side receives the data via Din pin.
