Description

Headline: Stop Guessing. Start Monitoring.

The Problem: Pressurized systems are the heartbeat of your operation, but analog gauges have a fatal flaw: they only work when you are looking at them. A silent pressure drop or a dangerous spike can go unnoticed for hours, leading to equipment failure, downtime, or safety hazards. You can’t be everywhere at once.

The Solution: The PressureAlarm is your always-on digital watchdog. It transforms dumb pipes into smart assets. It monitors your systems 24/7 with industrial precision and notifies you—instantly and globally—the moment something goes wrong. It comes ready to run with a 150 PSI sensor included.

🚀 PressureAlarm: Industrial IoT Monitoring System

Certified Golden Master • Revision 2026-02-10

A robust, dual-envelope pressure monitoring solution powered by the ESP32-C6. Designed for reliability, this system combines industrial-grade logic with a modern, responsive web interface.

🛡️ 1. Industrial-Grade Monitoring

• ⚖️ Dual-Envelope Protection: Simultaneously monitors for Low Pressure (leak/supply loss) and High Pressure (over-limit/danger).

• 🧠 Smart Debounce Engine: Features a 3-second stability lock to prevent false alarms caused by pump startups or hydraulic hammers.

• 🚦 Traffic Light Logic: System state automatically transitions between NORMAL (Green), WARNING (Yellow), and ALARM (Red) based on real-time sensor data.

• 🔌 Universal Sensor Support: Compatible with any 0.5V–4.5V Ratiometric Transducer.

  • Configurable Range: Swap an 80 PSI sensor for a 300 PSI sensor in seconds via the dashboard.

📈 2. Professional Data Visualization

• 📊 Integrated Charting Engine: Powered by Chart.js for buttery-smooth performance.

  • 🔴 Live Mode: Real-time streaming graph (1s updates) with zero load on the device memory.

  • 📅 History Mode: Instant trend analysis with 1H | 24H | 7D | 30D time-travel selectors.

• ❄️ Anti-Freeze Architecture: Smart file transfer logic (“breath cycle”) ensures the hardware LCD never freezes or lags, even while downloading months of data.

• 🧹 Robust Rendering: Automatically filters invalid timestamps and rebuilds charts on-the-fly to prevent axis conflicts.

💾 3. Black-Box Data Logging

• 📦 Offline-First Design: Records data to an internal binary Ring Buffer (log.bin). Works 24/7, even without WiFi.

• 🔄 Auto-Recycling: “Set and Forget” circular buffer automatically overwrites the oldest data when memory is full.

• 🎚️ Smart Capacity Slider: Interactive slider estimates storage duration (e.g., “~45 Days”) based on your chosen sample rate (30s–300s).

• 📥 Universal Export: One-click download of standard .CSV files, compatible with Excel, Google Sheets, and industrial analysis tools.

🔔 4. Smart Alerts & Notifications

• 📧 Direct Email Injection: Sends SSL/TLS encrypted alerts directly to any provider (Gmail, Outlook, Office365).

• 📱 SMS Gateway: Native integration with Twilio API for instant text message alerts.

• 📢 Rich Context Alerts: Notifications include:

  • Device Name & Unique ID

  • Specific Fault (e.g., “HIGH PRESSURE > 150 PSI”)

  • Timestamp

• ⏰ Nag Mode: Configurable “Repeat Timer” resends notifications (e.g., every 15 mins) until the alarm condition is resolved.

🖥️ 5. Modern Web Interface (UX)

• 📱 Mobile-First Design: Large touch targets (48px+) and responsive layouts optimized for smartphones and tablets.

• ⚡ Live Dashboard: Real-time AJAX updates (1000ms refresh) show current pressure, signal strength, and system status.

• 🔧 Calibration Wizard:

  • One-Touch Zero: Press “Capture Zero (0.5V)” and the system automatically aligns the sensor curve (9x Ratio). No high-pressure calibration needed.

🔒 6. Security & Connectivity

• 🔑 Role-Based Access: All dashboard controls and API endpoints are protected by Basic Authentication.

• 🌐 RESTful API: Open JSON architecture (/api/status, /api/settings) allows easy integration with SCADA or external dashboards.

• 🛡️ Tiered Reset System:

  • Physical Button (5s): Wipes WiFi credentials only (Lockout recovery).

  • Web Reset: Wipes all settings, logs, and calibration data (Factory Restore).

• 📡 WiFi 6 Ready: Optimized connection stability for ESP32-C6 RISC-V architecture.
