Powercast's Battery-Free RFID Sensor Condition Monitoring System is Best of Sensors Finalist

Powercast Corporation, the go-to source for the entire spectrum of wireless charging solutions, announced that its RFID-powered, wire-and-battery-free sensor condition monitoring system recently customized for data centers was named a finalist in the Best of Sensors Awards 2025 in the Power & Sustainability category. Powercast's technology will be displayed in booth #835 at Sensors Converge, June 24 – 26 in Santa Clara, CA, where award winners will be announced June 25.

Powercast collaborated with Asset Vue to customize its RFID sensing technology – known for maintenance-free monitoring because it can power itself perpetually from RAIN RFID inventory readers instead of wires and batteries – to monitor the temperature and humidity of mission-critical equipment stored on metal server racks without adding to the complexity of a data center.

Asset Vue wanted an affordable, maintenance-free monitoring system that didn't require hardwiring sensors or battery maintenance," said Charles Greene, Ph.D., COO/CTO Powercast. "They knew our technology did that, so they asked us to customize our RFID sensor tags to meet the needs of a data center.

Customizations included: 1) halving the size of Powercast's existing RFID sensors to fit into server racks and facilitate airflow to keep equipment cool, and 2) redesigning the RF receiving antenna to avoid interference from the metal racks while still providing long range wireless power to the sensors. The system is currently in beta testing at Asset Vue's data center, and Powercast plans to roll it out to other data centers later this year.
