A project log for DIY SCADA / smart home
A DIY smart home system the SCADA way...
Level 0: field devicesSensors: DHT11, DHT22, BH1750, HC-SR501, DS18B20Actors: stepper and DC motors, solenoid valves, radio controlled plugs and relays (433Mhz), IR-remote controlled devices
Level 1: I/O modulesRemote 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: coordinatingA Raspberry PI With Node-RED and Grafana to collect and store all my data. And Alexa voice control.
