# DIY SCADA / wireless and wired remote I/O

> a multi-purpose remote I/O (RIO) module for my DIY SCADA

Original author: stefan.schnitzer (source: https://hackaday.io/project/167904-diy-scada-wireless-and-wired-remote-io)

## Components

- **Arduino Ethernet Rev. 3** x 1 ([docs](https://docs.arduino.cc/retired/boards/arduino-ethernet-rev3-without-poe))

## Article

It is built to work within my DIY SCADA: <https://hackaday.io/project/14862-diy-scada-smart-homeIts> purpose is to connect any sensor or actor wireless to my smart home system.This is achieved with an Arduino and an ESP8266 (ESP-01) as a WiFi module.The Arduino (Level 1) transmits data via Modbus TCP/IP Protocol to the Level 2 (A Raspberry PI with CodeSys software PLC). Small functions are processed directly on the Arduino. ( for example the dosing on my cat-feeder <https://hackaday.io/project/167848-diy-scada-cat-feeder>)

## **DETAILS**

The example on my pictures shows a unit that has a motion sensor, a light sensor, and a 433Mhz transmitter ( to communicate to Smartwares <https://www.smartwares.eu/en-gb/smartwares>) packet in a 3D printed case. That case is designed to fit the wired variant of the remote I/O (with the Arduino ethernet shield) as well.
