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.

Internet and Intranet of Things - IoT

WSN - Wireless Sensor Networks and M2M - Machine to Machine Data Communication;

M2M and WSN is a closed private Intranet network that is used in Manufacturing and Industrial Automation. Here we could use data sync to Interface it with the Web or Internet. This enables passive controls and monitoring of SCADA or Machine Status, yet very Secure.

COR - Collaborative Online Robotics - This is like team work for bots. Big tasks can be accomplished by very small and weak robots. Example - Observe Ants and Bees.

All these only mean Wireless Networked Intelligent Embedded Systems. They could be machines, appliance, robot or gadget. The brain is both on the device and in the Clouds.

Modbus Communication Protocol Suite

Group of individuals and firms supporting and helping the implementation of Modbus communication protocol suite and the evolution to address architectures for distributed automation systems.

Modbus Communication Protocol Suite

Some Activities of the Modbus Organization are ...to Encourage, support and evolve ...
  • Participation in standards activities worldwide.
  • Leading the evolution of the Modbus protocol and its variants.
  • Modbus across a broad spectrum of physical layers and transmission media.
  • Conformance testing program to insure greater interoperability of Modbus devices.
Some Facts -

Modbus Protocol is a messaging structure developed by Modicon (Schneider Electric) in 1979. It is used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment.

The semiconductor industry has implemented a Network Communication Standard and an Object Messaging Protocol using Modbus TCP/IP. This allows SEMI Sensor Bus compatible sensors to communicate with each other using Modbus TCP/IP.

Spinwave Systems’ Wireless Thermostat Controller is a drop-in replacement for almost any existing conventional non-communicating thermostat, re-using the existing equipment wiring. Thermostat functions and values are accessible remotely through an embedded web page of the Modbus Mesh Gateway or via Modbus communication.



Wireless Thermostat Controller, SWC-TSTAT-1

The wireless thermostat controller is a full function wireless mesh device with integrated radio that can be configured to control heat pump systems, (with auxiliary or emergency heating if necessary), gas/oil heating systems with add on cooling, control high and low balance points as well as the number of heating and cooling stages needing precise control. It can even adapt to manage the number of fan speeds it must control.
