Data Center Temperature Monitoring Using Smart Passive Sensor Technology

by  ON Semiconductor  - 01-03-2018 

ON Semiconductor is enabling new sensing possibilities with the world’s first battery-free sensor tag. In this video, we will demonstrate an exciting new solution for temperature monitoring and asset tracking in a data center. ON Semiconductor’s battery-free wireless sensors are completely battery free that operate using UHF RFID protocol.

The video below demonstrates how these sensors can be used to monitor airflow temperature trends that can then be analyzed over time to detect failing equipment as well as optimize cool air flow throughout the entire data center.

Full Transcript:

Hello, my name is Walker Mitchell and I am an Applications Engineer at ON Semiconductor. Today I will be demonstrating an exciting new solution for temperature monitoring and asset tracking in a data center. Smart Passive Sensors are completely battery free, wireless sensors that operate using UHF RFID protocol. For a detailed overview of this technology, please refer to our SPS Technology and Ecosystem video. These sensors can be placed on each piece of equipment in a server rack, continuously monitoring inlet and outlet airflow temperatures. Airflow temperature trends can then be analyzed over time to detect failing equipment as well as optimize cool air flow throughout the entire data center.

The small form factor of the SPS tag allows it to be placed in non-intrusive locations, while its wireless capabilities allow it to stay with a single piece of equipment even if it needs to be moved from rack to rack. Staying with the equipment is invaluable as it enables you to track your assets using the unique RFID information on each sensor, while also linking that unique ID to the sensor’s historical temperature data.

This demo program allows us to visualize what kind of data we can collect using Smart Passive Sensors in a data center server rack. Each colored block represents an SPS tag, with the temperature and unique ID shown in each block. As we feed in some hot air from the bottom of the rack, the blocks at the bottom screen will show rising temperatures both numerically and visually through a change in color. If you would like more information about this application or SPS in general, please contact your local ON Semiconductor representative or visit onsemi.com. Thanks!
