Monitoring Temperature Sensor Data with an Arduino based PLC, MQTT, Node-RED, GridDB and Grafana

Project description

Overview This article provides a guide on how to create a system for monitoring temperature sensor data using an Arduino-based PLC, an MQTT broker, Node-RED, GridDB, and Grafana. The system involves connecting the Arduino-based PLC to a temperature sensor, configuring the Arduino-based PLC to publish temperature readings to an MQTT broker, using Node-RED to subscribe to the MQTT broker and store the temperature readings in GridDB, creating a dashboard in Grafana with a chart of the temperature readings stored in GridDB, and setting up notifications in Grafana to alert when the temperature…
