Tmote Sky & TinyOS
Tmote Sky:
Tmote sky is the next generation mote platform for extremely low power high data rate, sensor network applications designed with the dual goal of fault tolerance and development ease. Tmote sky boasts the largest on-chip RAM size of any mote, the first IEE 802.15.5 radio, and an integrated on board antenna peripherals including a 12 bit ADC and DAC, timer, 12C SPI and UART bus protocols and a performance boosting DMA controller. Tmote sky buy offers a robust solution with hardware protected external flash, applications may be wirelessly programmed to the Tmote sky module. In the event of a malfunctioning program, the module loads a protected image from flash. Toward development ease, Tmote sky provides an easy to use USB protocol programming, debugging and data collection.
Tmote Sky Specifications:
The features include 250kbps 2.4GHz IEEE 802.15.4. It has an integrated onboard antenna with 125m range integrated humidity and temperature sensor ultra low current consumption.
Tiny OS:
It was designed by the University of California, Berkeley by TinyOS developers. The Tmote Sky platform offers seamless vertical integration between the hardware and the TinyOS operating system. TinyOS is a small open source component based operating system also developed at UC Berkeley. TinyOS was specifically designed to support the networked sensor regime. TinyOS was in fact the first event driven operating system specifically made for wireless sensor networks. It was written in a variant of the C programming language named NesC. It is considered to as a component based operating system. The components are connected to each other by means of interfaces. It is possible to quickly program new applications using connected components with their interfaces. These are components of the highest level that implement protocols, hardware abstractions, data structures, services, etc. TinyOS is open source hence the programmes can combine and adapt the basic components that are really needed in the application and include it in the final executable file. Thus this reduces the amount of the mote memory required.

Wireless Sensor Mote Platform
A wireless sensor network consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a main location. The development of wireless sensor networks was motivated by military applications like battlefield surveillance; today such networks are being used in many industrial and consumer applications. This includes industrial process monitoring and control, machine health monitoring and so on. The wireless sensor network is build of nodes, from several hundreds to even thousands where each node is connected to one sensor.
Each such sensor network node has typically several parts; a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source in the form of a battery or an embedded from of energy harvesting. A sensor node might vary in size from that of a shoebox down to the size of a grain. The mote function within the network and typically full-fill one of the two purposes. Either data-logging, processing sensor information from the environment or acting as a gateway in the adhoc wireless network formed by all the sensors to pass data back to a collection point.
The IEEE 802.15.4 protocol has been adopted as a communication standard for the low data rate, low power consumption and low cost Wireless Sensor Networks. This protocol is quite flexible for a wide range of applications if appropriate tuning of its parameters is carried out. Most of the mote platforms use this standard for communication between the motes. TelosB mote is IEEE 802.15.4 compliant and use 2405 to 2480 Mhz band for communication. TelosB mote boards are typically powered from an external battery pack containing two AA batteries.
Advanticsys has been in this field since 2009 and is quite the solution provider. They in fact specialize at Wireless Sensor Networks.

Connect with New Age Wireless Device – Telosb Sensors
Summary: Wireless sensor devices are remarkable technological developments to catch up with the pace of growth of mankind.
Connect and share, are two words which have intertwined with human life so well that when added with legendry human race, become inseparable. The phenomenon of constant growth depends on this perfectly blend trio of the three. This undying spirit of humans led to the invention of number of such devices which can facilitate connecting and sharing for them. The latest in this crew are small sensor devices. These are miniature wireless sensor devices, connecting people anywhere on the earth. TelosB sensor and telosB mote are examples of such devices. The device named telosB sensor is designed with 8 sensor channels for optimum performance and can be safely used for different applications. While, telosB mote is a high power wireless transmission device, also known as smart-dust. A low-power computer is attached to this device as the base, which is connected to another set of sensors and a radio transmitter forming an ad-hoc network.
Tip: Update your co-worker with minute details, sitting in any part of the world, with no gap of time.
Advantages of shifting your network sharing on TelosB sensors
While listing the various benefits that can be derived from these devices, minimal energy consumption tops the list. Today, conserving energy is the prime motto for entire world, so introduction of such high powered yet energy efficient devices are a boon of entire mankind. They rather save huge amounts spent on energy costs. Moreover, these wireless sensors can monitor the positions and accelerations in units of light, sound, vibrations, humidity and pressure etc. Another striking feature of telosB sensors is that performance of the device remains unaffected by weather conditions, facilitating a flexible user interface and makes them more reliable. Also if you browse the costs incurred on installing these devices then you will find that telosB sensor and telosB mote price is quite meagre as compared to the advance functions that it can perform.
