Automate Your Sensor Data Ingestion with PostgreSQL
detail.loadingPreview
Streamline the process of collecting and storing sensor data directly into your PostgreSQL database. This workflow automatically generates sample sensor readings and ingests them every minute, ensuring your data is always up-to-date.
About This Workflow
This n8n workflow provides an elegant solution for automatically ingesting sensor data into a PostgreSQL database. It leverages a cron trigger to initiate the process every minute, simulating the generation of sensor readings. A function node then dynamically creates sample data, including a sensor ID, a random humidity value, a precise timestamp, and a notification flag. Finally, the Postgres node efficiently inserts this generated data into a designated table, making it readily available for analysis and monitoring. This workflow is ideal for scenarios where real-time data capture and storage are crucial.
Key Features
- Automated Data Generation: Simulates sensor readings on a schedule.
- Real-time Ingestion: Inserts data into PostgreSQL every minute.
- Dynamic Data Creation: Generates sensor IDs, values, and timestamps.
- Flexible Configuration: Easily adaptable for different sensor types and databases.
How To Use
- Configure the Cron Node: Set the
triggerTimestoeveryMinuteto initiate the workflow at regular intervals. - Customize the Function Node: Modify the
functionCodeto define your specific sensor logic, including howsensor_id,value, andtime_stampare generated. You can also adjust thenotificationflag as needed. - Set up the PostgreSQL Node: Provide your PostgreSQL connection details in the
credentialssection. Specify the targettableand thecolumnswhere the data should be inserted. Ensure your PostgreSQL database and table are set up to receive this data.
