About POSTS

Powered Overflow Sensing and Tracking System — a solar-powered flood monitoring and GIS route mapping solution for San Simon, Pampanga.

What is POSTS?

POSTS (Powered Overflow Sensing and Tracking System) is a solar-powered LED flood indicator and GIS-based route mapping system designed to monitor real-time water levels and communicate flood road conditions to the public and local government of San Simon, Pampanga.

How It Works

An ESP32 microcontroller connected to an ultrasonic sensor measures water depth continuously. Data is transmitted via Wi-Fi to a local PHP API, stored in a MySQL database, and displayed on this dashboard. LED indicators on the physical unit reflect current flood levels.

Coverage Area

The system monitors flood-prone roads and waterways in San Simon, Pampanga — an area historically affected by seasonal flooding due to proximity to Pampanga River tributaries. GIS mapping provides evacuation route guidance during high-water events.
