MQTT Simulator

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.
