## Overview

This ESP32 TPMS reads tire pressure through a load cell and HX711, evaluates the reading against a configurable threshold, displays pressure, and activates alerts when pressure is high. The README documents these capabilities, but no source excerpts were provided; wiring and implementation details beyond those documented relationships are therefore omitted. The tree identifies the sketch as `sketch.ino`, although the README refers to `tpms.ino`.

Main entry points: [`sketch.ino`](https://github.com/ahmetygtozay/tire-pressure-monitoring-system-with-esp32/blob/main/sketch.ino) (TPMS Sketch)

## Connections

- Tire Pressure → Load Cell + HX711: applies pressure
- Load Cell + HX711 → TPMS Sketch: provides reading
- TPMS Sketch → Threshold Check: checks reading
- TPMS Sketch → OLED Display: displays pressure
- Threshold Check → LED Alert: high pressure
- Threshold Check → Buzzer Alert: high pressure
