Summary
This article proposes a novel passive and semi-passive sensing system for ultra-high voltage
Read more Read less(UHV) equipment monitoring based on the Passive Internet of Things(P-IoT). By utilizing electromagnetic and solar energy harvesting, it completely eliminates battery dependence.
The system integrates Micro-Electro-Mechanical Systems (MEMS) temperature sensors with dual-mode communication—passive On-Off Keying (OOK) backscatter and semi-passive
Binary Phase Shift Keying(BPSK)—via a custom Radio Frequency RF front-end and robust triple Field Programmable Gate Array (FPGA) baseband, successfully mitigating electromagnetic interference. Field tests validate its extreme resilience, achieving stable communication over 150 meters and ±0.5 °C tracking accuracy under 1450 kV lightning impulses and 630 kV industrial frequencies. Ultimately, this maintenance-free solution significantly reduces costs and enhances smart grid deployment scalability.
