Sensor Selection for Wireless Sensor Networks

May, 2009
By Dick Alderman, VP Sensor Engineering
Wireless sensor networks are being deployed to monitor a wide range of environments. Site facility Power Use Effectiveness (PUE) is critical in these deployments. Sensor parameters require a careful study for performance, energy use, calibration, footprint, interface, intrusiveness, standards and ease of deployment. Many of these requirements are assisted by selecting best in class MEMS technology from tier 1 suppliers. Download now

SynapSense Sensor Technology Cuts Yahoo's Cooling Bills

August 14, 2008
Analysts: Jeff Paschke, Andy Lawrence
In the drive to make datacenters more energy efficient, many operators have been assessing the use of intelligent or dynamic cooling. The goal is to make more extensive use of variable frequency drives, with the optimal amount of cooling targeted at exactly where it is needed, in real-time and under automated control. In this way, overprovisioning of cooling can be reduced dramatically. Download now

Co-existence and Security White Paper

July 2008
By Dr. Raju Pandey, CTO, SynapSense Corporation
SynapSense wireless sensor network (WSN) solutions extend the enterprise IT infrastructure to key equipments, products, and facilities. They can monitor everything from specific equipments (such as power, vibration and utilization) to global environmental conditions (such as ambient temperature, humidity and air pressure). In addition, they provide application intelligence to characterize the state of the equipments or the environment, and to effectively adapt their behavior. Download now
