Postgres Data Ingestion
This workflow automates the generation and storage of sensor data. Every minute, it generates data that includes the sensor ID, a random humidity value, and a timestamp, and writes this information into a PostgreSQL database. It effectively addresses the need for real-time data collection and storage, eliminates the need for manual intervention, and enhances the automation and accuracy of data processing. This workflow is widely applicable in monitoring systems and smart home applications within the Internet of Things (IoT) environment.
