Wireless Sensor Networks for Green Data Centers
The ability to reduce energy consumption is critical in data centers, which are among the largest consumers of energy in the world. In fact, data centers collectively represent the fifth largest use of electricity in the US. One-third to one-half of the electricity consumed by the data center comes from air conditioners, fans, dehumidifiers, and pumps.
Benefits of wireless sensor networks, (WSN) for data center energy management:
- Lowers data center operating costs by reducing energy consumption up to $9 per square foot
- Delivers improved availability by reducing data center downtime
- Eliminates installation of cable or conduit and reduces costs association with rewiring and reconfiguration
- Simplifies data center reconfiguration and retrofits
SmartMesh-enabled WSNs are uniquely able to be deployed in a data center without requiring any cable or conduit—an entire temperature, pressure and humidity sensing network can be deployed without a moments disruption to data center operations, and with no construction required. The ability to get better information about the thermal condition of the data center is critical to manage this environment, and allows IT managers to operate the data center at lower overall cost and higher availability than ever before.
For example, a SmartMesh-enabled sensing and control system developed by Vigilent measures temperatures at critical locations throughout the data center, and can automatically adjust the amount of cold air produced by cooling units, directing that cold air to the proper locations through variable speed fans and remote vent controls. Read the case study.
Only wire-free solutions based on SmartMesh allow sensors to be placed in exactly the right location to optimize energy performance and ensure reliability of the thermal environment while preserving the flexibility required for IT equipment upgrades.
Adding an intelligent sensing system to the data center can reduce the energy consumption in an average data center by hundreds of thousands of kilowatt-hours annually. With data centers expected to increase by 40 to 50 percent nationally in the next four years, the imperative to change is upon us.

- Improves process safety by automating activities previously unmanageable with a wired solution
The rock-solid reliability and simple installation and management of SmartMesh WirelessHART-enabled solutions lets engineers get the measurements they need, when they need them to improve productivity. And, by leveraging field devices based on the WirelessHART (IEC62591) standard, device commissioning is just as simple as in the wired world—no need for new skills, tools, or consultants. Real-world installations have demonstrated that self-organizing WirelessHART networks provide a 90% reduction in installation cost compared to wired sensors, knocking down the barrier to widespread deployment of sensors in the industrial environment.
For example, the GlaxoSmithKline plant in Cork, Ireland, is a strategic operation, manufacturing many of the active ingredients used in the formulation of prescription drugs. To increase productivity, they added two new water storage tanks. Wanting to measure water levels and usage, GlaxoSmithKline selected Emerson Process Management’s Rosemount® Smart Wireless flow and pressure transmitters because of the reduced installation costs and because it would be easy to expand the network without disrupting operations or data collection. Using Dust Networks® SmartMesh® technology, the Rosemount Smart Wireless product family created a resilient, reliable and secure wireless mesh sensor network over which to transmit sensor data without digging trenches and laying cable, reducing installation costs significantly. The SmartMesh intelligent network also allowed secure, non-disruptive expansion of the network as needed. Click here for case study.
Machine Health Monitoring
As plant infrastructure ages, equipment failures cause more and more unplanned downtime. The ARC Advisory Group estimates that 5% of production in North America is lost due to unplanned downtime. Wireless makes it economically feasible to monitor many more pieces of plant infrastructure - not just the few deemed critical.
While leading manufacturers fully understand the value of predictive maintenance, until now the challenge has been the sheer impracticality of installing sensors on every piece of aging infrastructure.
Aging pipelines and tanks have become a major problem in the oil and gas industry. Monitoring corrosion using manual processes is extremely costly, time consuming, and unreliable. A network of wireless corrosion sensors can be economically deployed to reliably identify issues before they become catastrophic failures.
Rohrback Cosasco Systems, the market leader in corrosion monitoring products and services for process industries, addresses the needs of today's critical infrastructure with the SmartMesh WirelessHART-enabled RCS Microcor Wireless Transmitter, which enables rapid communication of corrosion rate data, extending overall asset life and providing peace of mind with respect to potential environmental mishaps caused by corrosion.
When the world leader in biological specimen management wanted to reduce the use of manual logs in its facility, the company had two objectives in mind: increase productivity and continue to ensure that validation results of each test met stringent FDA requirements.
A SmartMesh-enabled wireless sensor network was selected over a hard-wired solution because it eliminated sterility concerns of hard-to-clean wiring conduit, and provided ease-of-installation when measuring conditions in incubators, refrigeration units, ductwork, and rotating equipment. The system allows technicians to remotely view real-time data and compile historical sensor data, providing considerable savings in time and labor.

In the case of CITRIS (Center for Information Technology Research in the Interests of Society) in collaboration with Roger C. Bales, UC Merced, and Steven D. Glaser, UC Berkeley, they needed to measure and report on conditions of the snow pack in the Sierra Nevada Mountains. Snow information is used to anticipate droughts and floods, to equably allocate water resources between the public and private sectors of the economy, and is key to agricultural planning. In addition to snow depth, they also needed to measure solar radiation, relative humidity, soil moisture, matric potential, and temperature. Read the case study here.
The SmartMesh products underpinning this water management solution provide long battery life, intelligent networking features and detailed network statistics for optimizing sensor placement that allow CITRIS to efficiently gather real-time water content data from the snow pack, using hundreds of sensors distributed throughout a remote, mountainous and environmentally harsh region.
