IoT data collection involves mass equipment and data, EMQX + ClickHouse is fully capable of IoT data access, storage, analysis and processing.
Taking the common scenarios of Internet of things as an example, this article introduces how to use the EMQX message middleware and the open source data visualization solution of InfluxDB + Grafana to conveniently display a large amount of time-series data of IoT devices.
This example will demonstrate how to report the temperature and humidity data collected by the DHT11 sensor to the MQTT service in the cloud through the MQTT protocol and the NodeMCU based on ESP8266 , and show how the application subscribes to and processes the data.
