Clean and Log IoT Sensor Data to InfluxDB via Webhook

This n8n workflow streamlines IoT data processing by accepting JSON-formatted sensor readings via an HTTP POST webhook. It uses a Function node to validate data, filter out-of-range or noisy values, round measurements, and format timestamps for consistency. A Set node handles configurable parameters like InfluxDB host, credentials, and measurement names, ensuring flexibility across environments.

The cleaned data is then inserted into InfluxDB via the dedicated node, enabling efficient time-series storage optimized for high-volume sensor inputs. This setup supports real-time dashboards in tools like Grafana or Chronograf, providing actionable insights without manual intervention.

Perfect for renewable energy sites tracking solar/wind metrics, smart farms monitoring soil/humidity, and environmental stations logging air quality. Benefits include reduced data errors, automated scalability, time savings for developers (setup in minutes), and robust integration for production IoT deployments.
