Remote IoT Sensor Monitoring with MQTT and InfluxDB

This n8n workflow enables remote IoT sensor data collection and storage by integrating MQTT, JavaScript processing, and InfluxDB. It listens to a weather topic via MQTT from an ESP32 device with a DHT22 sensor, extracts temperature and humidity data, formats it correctly, and posts it to an InfluxDB database for analysis or visualization. The setup is ideal for IoT applications requiring continuous environmental monitoring, enabling real-time data logging and remote management.
