Temperature Alert System Using Kafka and Vonage

This n8n workflow listens to a Kafka topic for incoming messages and triggers an SMS alert if a temperature value exceeds 50. The workflow begins with a Kafka trigger node that subscribes to ‘topic_test’. When a message arrives, it checks if the ‘temp’ value in the message exceeds 50. If so, it sends an SMS notification via Vonage, alerting the user about the high temperature. If the condition isn’t met, it proceeds with a no-operation node, effectively doing nothing further. This automation is useful for real-time monitoring of temperature data, enabling immediate alerts for temperature anomalies or critical conditions.
