ECPROBE

A simple EC Probe using a 555 timer, some resistors, capacitors and an Arduino Uno.

EC Probe (Electrical Conductivity & TDS Sensor)

This project measures electrical conductivity (EC) and estimates total dissolved solids (TDS) in liquids using an Arduino-compatible microcontroller.
It also includes temperature compensation and serial user feedback for real-time monitoring.

Built with PlatformIO for reproducibility and modular design.

Features

• Conductivity measurement using probe input.
• Temperature sensor support for compensation.
• User feedback via serial monitor (with ANSI escape codes for clean UI).
• Modular design for easy extension (conductanceRead, tempRead, userFeedback).

Hardware Requirements

• Arduino-compatible microcontroller (e.g., Uno, Nano, ESP32).
• EC probe (2-pin or 3-pin, analog input).
• Temperature sensor (e.g., DS18B20, NTC thermistor).
• Breadboard, jumper wires, USB cable.
• Develop your own probe architecture.

Software Setup

1. Install VS Code + PlatformIO IDE.

2. Clone this repo:

   git clone https://github.com/antonykasera/ECPROBE.git
   cd ECPROBE

3. Open the project in VS Code → PlatformIO should auto-detect platformio.ini.

4. Build & upload:

pio run --target upload

5. Open serial monitor:

   pio device monitor
