IoT Dashboard & Supplies (Gas + Water)
Objective
Monitor critical supply levels (LP Gas and Water) in real time to automate restocking and prevent operational shutdowns.
Proposed Architecture
1. LP Gas (Stationary Tank)
- Challenge: Safe measurement in pressurized/explosive environment.
- Solutions:
- Option A (Magnetic/Hall): Sensor compatible with Rochester gauges (TwinSite). Magnetically attaches and reads the needle position. (e.g., industrial brands or DIY with ESP32 + Hall).
- Option B (Computer Vision): ESP32-CAM pointing at the analog gauge. Takes periodic photo → OCR/AI → Digital data. (Cheaper, less invasive).
2. Water (Cistern)
- Solutions:
- Ultrasonic (JSN-SR04T): Waterproof sensor on the lid. Measures distance to the surface.
- Hydrostatic Pressure: Submersible sensor at the bottom (4-20mA). Greater precision, unaffected by condensation.
3. Technology Stack
- Edge: ESP32 (WiFi Microcontroller) at each branch collecting data.
- Protocol: MQTT or HTTP POST to central server.
- Backend: Node.js/Python processing readings.
- Alert Logic:
IF level < 15% THEN Trigger Alert (WhatsApp/Telegram).- Consumption prediction (“Runs out in 3 days”).
- Frontend: Integration into the
v0-lcx-pwaPWA (Historical graphs and current gauge).
