    Xbee

    Xbee is a wireless communication device from digi.com that uses ZigBee protocol. “ZigBee is a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4-2003 standard for wireless personal area networks (WPANs), such as wireless headphones connecting with cell phones via short-range radio. The technology defined by the ZigBee specification is intended to be simpler and less expensive than other WPANs, such as Bluetooth. ZigBee is targeted at radio-frequency (RF) applications that require a low data rate, long battery life, and secure networking.” (from wikipedia)
     
    It operates with 3.3V and uses 50mA (series 1). Some Xbee ‘s pins can be set as Analog Input, Digital Input, Digital Output, or Analog Output (PWM). The numbers of pins are up to seven channels of analog input, nine channels of digital I/O and two channels of PWM. This means you do not need microcontroller to send sensor input to your computer. This example need two Xbee  Series 1 802.15.4 with firmware version 10A1 or later (I used 10A5), or two Xbee Seriese 2 with  ZNET 2.5 CORDINATOR API and  ZNET 2.5 ROUTER/END DEVICE API firmware. The following setup is  how to do Sensor-Xbee-Comp connection with Xbee  Series 1 802.15.4.

      Hello,
      I bought a Xbee, s1, module. I tried to make a communication between PIC microcontroller and MATLAB software on labtop. It works very well at small distance e.g. 1-3 m but if distance becomes larger the communication between them is lost whether was inside or outside . although in the datasheet of Xbee was mentioned that the distance can be 100 m.
      I read the power level, it was at the highest level. I only changed the data rate to 115200 bit/sec.
      I don’t know what I should do to reach to 100 m distance ???
      would you help me??
      Thank you.

      hi
      plz help me for create the communication between 2 xbee for S/R data to a microcontroller too.
      tnx.

      hi,
      I want to access zigbee pro using matlab plz help me for that.
      i am interested in RSSI of zigbee, i want the information of that pin using matlab.
