IoT Sensor Data Processing and InfluxDB Logging Workflow

This n8n workflow automates the collection, cleaning, and storage of IoT sensor data into an InfluxDB database. It begins with a Webhook trigger that receives data via an HTTP POST from IoT sensors. The data then passes through a Function node which validates and cleans the sensor readings, ensuring they are within acceptable ranges and properly formatted. Next, a Set node configures the database connection details such as host, token, bucket, and organization. Finally, an HTTP Request node sends the processed data to InfluxDB using its API, logging temperature, humidity, voltage, and timestamps for future analysis.

This workflow is practical for IoT deployments needing real-time data validation, transformation, and seamless storage in time-series databases, enabling efficient monitoring and analysis of sensor networks.
