Spinwave Systems expands line of wireless Data Center Sensors

Spinwave has recently introduced a new sensor line with significantly more range than earlier models. The new sensor has an open field range of 1,000 Ft. (300 m), which is a 60% increase over the 600 feet in earlier models.

The redesign provides increased configuration flexibility, enabling the introduction of several new sensors, designed for monitoring of server racks in data centers. A single sensor can now monitor temperatures at the top, middle and bottom of a rack. Additionally, sensors that monitor both temperature and relative humidity and analog input sensors are available.

A single receiver/gateway now supports up to 50 wireless sensors/transceivers and 200 measurement points.

Growth in the data center market is exceeding the overall growth in other markets by a wide margin. A recent survey by Datacenter Dynamics Research reports investment of about $30 billion during 2010-2011 and is projected to rise by over 16% to $35 billion in the coming 12 months.

This growth is fueled by escalating connectivity requirements, explosion of cloud computing, and an increasing emphasis on data mining, which is driving a major expansion of data center capacity. The result is a demand for more computing power, server density and a corresponding increase in heat loads, resulting in rapidly escalating energy costs.

Data center operators are faced with two major and seemingly contradictory challenges:

Uptime: Customers demand connectivity! Maintaining uninterrupted operations isPriority 1.

Energy Management: 50% of energy costs in data centers are to power servers. The other 50% ia spent to cool them. Given the escalating cost of energy, energy management has rapidly risen to Priority 1A.

Sensor-based Environmental Monitoring Systems help to achieve these seemingly contradictory objectives!

Environmental monitoring, based upon data provided by sensors deployed throughout a facility, provide a real-time picture of the state of a data center. This enables operators to detect existing problems and potential problems, allowing timely corrective actions to ensure uninterrupted operations.

The data provided enables operators to develop energy management strategies such as running the data center at higher temperatures or running air conditioning units based on actual cooling demand.

Data centers are a dynamic and changing environment, characterized by frequent server upgrades, infrastructure changes and rack re-configurations. Wireless sensor networks are ideal in this environment, due to installation flexibility and ease of deployment.

Spinwave is enjoying increasing market share in data centers due to its highly reliable sensor networks and products.

Spinwave Products Feature:

High Reliability: A Spinwave network utilizes a mesh architecture and a wireless protocol which allows multiple routes for data to reach its destination. It utilizes a frequency hopping scheme (A3) that avoids RF interference by continuously and seamlessly scanning all 16 channels in the 2.4 GHz spectrum for interference and automatically selecting the best channels to ensure maxiumum transmission reliability.

Low Installation Cost: Wireless – no conduit, wiring trays, or other construction related activities.

Easy Deployment: A complete temperature, humidity, and air pressure monitoring network can be installed rapidly with no disruption to data center operations.

Multiple Data Gateways: Integration with data center monitoring systems can be quickly and easily accomplished using common industry protocols – BACnet, LON, Modbus and SNMP.

Flexibility and Scalability: Spinwave’s system can be used to monitor servers in a closet or scale to a major data center. Since the sensors are wireless, they can be easily moved as configurations change or can be used on a temporary basis to monitor a specific zone, aisle, or rack.

Proven: Spinwave products are field tested with thousands installed in data centers, commercial buildings, industrial plants, hospitals, warehouses and educational facilities.

Spinwave releases new Modbus RTU, BACnet MS/TP and N2 Receiver/Gateway

The latest version of Spinwave Systems’ SWRF-MODBUS-RTU and SWRF-BACNET-MSTP receiver/gateway now allows changing communication parameters, like baud rate and Node ID, via DIP switch settings.

Additionally, three protocols are supported by the same module and the user can field-select between:

  • BACnet-MSTP
  • Johnson Controls N2
The new product release reduces stock part numbers and allows to easily change protocol settings in the field, without the need of additional software tools.

Spinwave Systems enables Energy Efficiency Case Studies

An ongoing case-study on residential energy-efficiency is being conducted by  students in the Energy Services Program at the Lakes Region Community College (Laconia, NH) and data is being published on Energy Matters – New Hampshire.

The goal is to provide non-biased information to consumers about how to save energy and replace fossil fuels with renewable energy.

Three different New Hampshire residences have been selected and are monitored using Spinwave Systems’ wireless sensor networks. Data is continuously pushed to the “Cloud” and can be accesses via an ECO-Dashboard, based on Google’s Visualization API.

All three homes were built in 2009:
1. A home built to code, (IECC 2006).
2. An energy efficient home (triple pane windows, foam insulation, ICF’s, geothermal heating and cooling).
3. A Passive solar home which is well insulated and has a PV system.

Spinwave wireless sensors monitor energy efficiencyTemperatures, relative humidity, HVAC run-times and energy consumption are logged in a relational database (mySQL) and real-time and historical data can be accessed and analyzed via the Eco-Dashboard.

Wireless sensors are positioned at strategic outdoor and indoor locations to monitor comfort levels, weather influence and energy consumption.

The goal of the case study is to help consumers to identify the best energy-efficiency investment for their particular situation.

Spinwave Systems releases wireless RTD sensor for extreme temperature applications

Wireless freezer monitoring, heat trace monitoring and oven temperature sensing are just a few applications requiring sensors supporting an extreme temperature range (-200°C to +850°C), high resolution (0.05°C / 0.1°F) and high accuracy.

Spinwave Systems’ new wireless RTD transceiver (SWS-2PT100)  supports 2 PT100 sensors in 2-wire and/or 3-wire configuration.
The product features a high-power radio for open field ranges up to 3,500 feet (1 km) and can be battery-powered or powered by a 9VDC  supply.
The SWS-2PT100 is part of Spinwave’s A3 product line, known for its ultra high reliability in harsh RF environments. Based on the IEEE  802.15.4 standard, the system outsmarts changing RF interferences with self-adapting frequency agility.

The product is available pre-mounted inside a NEMA4X fiberglass enclosure with either battery power or integrated 120VAC/9VDC power supply.
The power supply version also functions as a wireless mesh repeater.
