THE PRESIGNAL EM SENTINEL: A Camera-Free Long-Duration Electromagnetic Monitoring Node for Geological Plasma Discharge Research

Authors/Creators

  • 1. Presignal Inc.

Description

We describe the Presignal EM Sentinel, a camera-free, solar-powered, continuously operating electromagnetic monitoring node designed for long-duration deployment at geological plasma discharge candidate sites. The instrument integrates ten independent sensor channels covering the ULF magnetic, atmospheric electric field, ground conductivity, and optical emission spectrum domains. All data is GPS-timestamped and uploads via WiFi to the Presignal anomaly intelligence dashboard at ufosworldwide.com. This integration facilitates real-time correlation between local electromagnetic anomalies and global reporting trends, providing the multi-year site-specific baseline required for statistically meaningful analysis of observed discharge events.
