Industrial Automation using Node-RED Dashboard and Raspberry pi
As Node-RED is an IoT tool and Raspberry pi can be used as a controller and processor, we can deploy Node-RED and Raspberry pi to collect data from sensors. Based on the sensor data and user-defined data from the Node-RED dashboard, we can control the dryer fan, heater, spray, and flap to dehumidify.
Components used:
- Raspberry Pi
- Arduino Uno
- Arduino ethernet shield
- Temperature sensor
- Humidity sensor
- Wifi router
- Relay module
- 7'' Raspberry Pi touch screen display
I have used the Arduino Ethernet shield to collect sensor data. After collecting data, Arduino will send data to Raspberry Pi through the MQTT protocol.
Video documentation of the project:
You can get an idea of how the system implemented by watching the video.
Node-RED Flows:
- Admin
- Pi Operations
- Input Data
- Fan Control
- User input DB
Node-RED Node used:
You can download and install the flows from the Node-RED plotter or from the official pages of the individual node.
- Node-RED default dashboard
- MSSQL
- GPIO etc.
You have to customize the database information and edit table info.
Communication Protocol:
The Pi Operations flow is given below:
