    FireFly WSN Platform

    The main Firefly board uses an Atmel ATmega1281 8-bit micro-controller with 8KB of RAM and 128KB of ROM along with Chipcon’s CC2420 IEEE 802.15.4 standard-compliant radio transceiver for communication. The maximum packet size supported by 802.15.4 is 128 bytes and the maximum raw data rate is 250Kbps.

    FireFly WSN Platform

    FireFly Power Monitoring and Control Board  - In this project, we design and implement a remote switch control and power measurement system by using CMU Firefly wireless sensor board. The basic function for the system is that one central node can remotely switch on or off electronic devices and get the information, e.g. power, back from the switches. The basic design includes three parts: switch module, power measurement module and CMU Firefly board.

    FireFly Power Monitoring and Control Board

    The demonstration shows that central node can wirelessly control the four lamps individually and the accurate power from each of the node is transmitted back instantaneously. The functions such as power-save and autoswitch pattern are also implemented. The power measurement ranges from 10W to 1000W, which is suitable for most industrial electrical system.

    Internet and Intranet of Things - IoT

    When Intelligent Devices (embedded systems) are privately and securely networked, it is called the Intranet of Things. This is like a Home-Office-Business private closed Cloud. This is ideal for Home and Infrastructure Automation and even Big Business or SMB Automation.

    The Internet of Things - IoT is the Superset. It could be Secure and Private but still vulnerable to security lapses and breakdowns. This could send devices, robots and machines Berserk.

    In all Networked Environments we have to have fallback arrangements when network fails or is compromised or even slow due to peak hour internet traffic.

    By using channel cascading, we can configure this board with 2048 bins for each channel at the expense of a lower analog bandwidth of about 500 MHz. The on-board comparators enables the board to do a self-triggering on a programmed level of any of the input channels or logical combination of channels, much like an oscilloscope.

    Highlights of Board with One DRS4 chip
    • Four 50-Ohm terminated input channels with SMA connectors
    • Active input buffers which result in an analog bandwidth of 700 MHz (-3dB).
    • One AD9245 ADC to digitize signals from the DRS4 chip

    Instant Embedded client - Tuxgraphics

    An embedded client that works almost everywhere and all you have to do is: connect it to the network and power it on.

    Instant Embedded client - Tuxgraphics

    "The idea for a network client that reports data to a server was born a while ago when a marketing company contacted me. They wanted to display water and air temperatures live on their homepage."

    Instant Embedded client - Tuxgraphics

    The embedded client system uses a DHCP client to obtain an IP address and other network parameters such as gateway address and the netmask from your DSL-router or Cable-router. This process is totally automatic and happens as soon as board is powered on.

    The board uploads then periodically measurements to a server in the internet (aka server in the cloud). When you purchase an embedded client board pre-loaded with software then the access to the data receiving server is included.
