Interface Zigbee With PIC

Description

Zigbee devices can transmit data over long distances by passing data through a mesh network of intermediate devices to reach more distant ones. Zigbee is typically used in low data rate applications that require long battery life and secure networking.

  • The Zigbee is the name of a wireless protocol maintained by the IEEE 802.15 standard.
  • This is a protocol specified for Wireless Personal Area Network (PAN) using low powered wireless transceivers.
  • They have an approximate range of 10 to 100 meters.
  • They can communicate with other devices using the simplest serial communication protocol.
  • Zigbee uses only two Zigbee modules in which one of them transmits the data and another one receives data.
  • The Zigbee module made communication using serial communication protocol with the interfacing devices they can be connected to a microcontroller using a minimum of four pins.
  • They are
    1.Power supply.
    2. Ground.
    3. UART Data Out.
    4. UART Data.
  • Zigbee networks are secured by 128-bit symmetric encryption keys.

Application

  • Wireless light switch.
  • Electrical meter.
  • Traffic management system.
  • And other consumer and industrial equipment.
