MQTT Simulator

The technical documentation of the iotsensorsmqtt microservice, which simulates sensors sending data to the MQTT broker.

This microservice is a community contribution and is not part of the main stack of the United Manufacturing Hub, but is enabled by default.

The IoTSensors MQTT Simulator is a microservice that simulates sensors sending data to the MQTT broker. You can read the full documentation on the

GitHub repository.

How it works

The microservice publishes messages on the topic ia/raw/development/ioTSensors/, creating a subtopic for each simulation. The subtopics are the names of the simulations, which are Temperature, Humidity, and Pressure. The values are calculated using a normal distribution with a mean and standard deviation that can be configured.

Kubernetes resources

  • Deployment: united-manufacturing-hub-iotsensorsmqtt
  • ConfigMap: united-manufacturing-hub-iotsensors-mqtt


You can change the configuration of the microservice by updating the config.json file in the ConfigMap.
