Intelligent Flow Monitoring System with Predictive Analytics

We have developed a comprehensive solution that democratizes access to advanced water monitoring technology by combining:

Affordable hardware: Using ESP32 XIAO, inexpensive flow sensors, and standard components with an approximate cost of 350, 000 pesos per system

A capacitor

A 5V power supply

Resistors

Intelligent backend: Automatic analysis platform that detects anomalous patterns and predicts potential leaks before they become apparent

The Python backend used a database with the following initial schema

The frontend allows for a pleasant understanding of the

##code
