# DIY SCADA / smart home

> A DIY smart home system the SCADA way...

Original author: stefan.schnitzer (source: https://hackaday.io/project/14862-diy-scada-smart-home)

## Components

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

## Article

## **ESCRIPTION**

It controls lights, heating, ventilation, a robot vacuum cleaner, and even an automated cat feeder. Its Levels referring to the diagram Functional levels of a manufacturing control operation (see 2. in details) are:

Level 0: field devices
Sensors: DHT11, DHT22, BH1750, HC-SR501, DS18B20
Actors: stepper and DC motors, solenoid valves, radio-controlled plugs and relays (433Mhz), IR-remote controlled devices

Level 1: I/O modules
Remote input/output (RIO) modules made from Arduino's which sends the sensor data to the CodeSys software PLC and directly controls critical functions (as feeding the cats, positioning roller blinds).
Additionally a Pixtend I/O Board is connected to a Raspberry PI.

Level 2: supervisory
A Raspberry PI with CodeSys software PLC and graphical HMI which controls

Level 3/4: coordinating
A Raspberry PI With Node-RED and Grafana to collect and store all my data. And Alexa voice control.
