Generate & Insert Sensor Data into Postgres DB
Automates periodic generation of fake sensor data (e.g., humidity) and inserts it into a Postgres database for testing or monitoring.
This n8n workflow simulates sensor data ingestion by running every minute via a Cron node, generating randomized humidity readings with timestamps using a Function node, and inserting them into a Postgres table. It requires a Postgres database with a predefined table (n8n: id SERIAL, sensor_id VARCHAR, value INT, time_stamp TIMESTAMP, notification BOOLEAN). Ideal for blog tutorials on database monitoring.
Benefits include easy setup for testing data pipelines, alerting systems, or time-series d
