Gatekeeper IoT connects ESP32-C3 microcontrollers with a zero-latency WebSocket backend, local SQLite access logging, Telegram security alert engines, and Cloudflare Tunnel infrastructure.
Gatekeeper IoT pairs low-power hardware microcontrollers with enterprise Node.js microservices.
Runs persistent C++ WebSocket firmware (Project_Gatekeeper.ino) with non-blocking auto-reconnect routines.
Dedicated isolated relay channel drives a 500ms momentary high-pulse signal directly into existing automated gate control panels.
Reads analog LDR light sensors and digital temperature/humidity probes for physical enclosure health and environmental monitoring.
Instant push notifications for late-night openings (10 PM - 5 AM) and "Gate Left Open" safety warnings (> 3 min).
Every gate activation request is recorded in local gatekeeper.db with user identity, timestamp, and hardware execution status.
Exposed via encrypted Cloudflare Tunnel (gate.microdrive-tech.com) without opening public router ports or exposing home IPs.
