Kafka Temperature Monitor: Send SMS Alerts on High Temp
Listens to Kafka topic for temperature data and sends SMS alert via Vonage if temp exceeds 50. Ideal for real-time IoT or sensor monitoring.
This n8n workflow automates real-time monitoring of a Kafka topic named 'topic_test'. It triggers on incoming messages, parses JSON data, and evaluates if the 'temp' value surpasses 50 using an IF node. If true, it dispatches an SMS notification via Vonage with details like 'Alert! The value of temp is [value]'. Otherwise, it executes a NoOp node.
Benefits include instant alerts without custom coding, reducing response times for critical thresholds in IoT setups, server farms, or environmental sensors. It saves hours of development for Kafka-Vonage integrations and scales effortlessly with n8n's no-code interface.
Use cases: IoT device monitoring (e.g., fridge temps), industrial sensors, data pipeline anomaly detection, or DevOps alerts for metrics exceeding limits. Customize topic, threshold, and message for broader applications like stock price surges or website traffic spikes.
