# IoT Node Setup - Universal Sensor Logger

**IoT Node Setup** is a robust, industrial-grade data acquisition and logging system based on the ESP32 microcontroller. It is designed to interface with various sensors (Analog, Digital, Modbus RTU/TCP) and transmit data to central servers via MQTT or HTTP, with support for both WiFi and Ethernet (W5500) connectivity.

This project was developed during an internship program at ** PT Medion Farma Jaya**.
