Type: Mote

The CM5000-SMA mote is IEEE 802.15.4 compliant wireless sensor node based on the original open-source "TelosB" platform design developed and published by the University of California, Berkeley (“UC Berkeley”). These modified series of the CM5000 motes makes use of an external 5dBi SMA antenna, which makes it a powerful platform for applications where an extended range is needed. The mote has the following general characteristics:

  • IEEE 802.15.4 WSN platform
  • TI MSP430F1611 Microcontroller
  • TI CC2420 Radio Transceiver
  • TinyOS 2.x & ContikiOS Compatible
  • Temperature, Humidity, Light sensors
  • User & Reset Buttons
  • 3xLeds
  • USB Interface
  • 2xAA Battery Holder
  • External 5dBi SMA antenna

This product is specially suitable not only as cots environmental wireless sensor node, but also as a very useful research platform for developers, as it includes in the same hardware module all the needed functionalities: sensor readings, processor power and wireless communication potential.

Warning: To avoid damage to this device, make sure to remove batteries before plugging it to the host computer's USB port.
