EnvironmentReader

This IoT application connects to either or both temperature and humidity sensors, periodically reads values and writes the resulting data to Kafka.

Configuration

The Kafka endpoint, Kafka topic and read interval can be set in the appsettings.json configuration file:

{
  "Kafka": "<host>:<port>",
  "Topic": "openmts-environment-<storage_site.id>",
  "ReadIntervalInSeconds": 20,
  "Temperature": {
    "Provider": "MockTemperatureProvider",
    "Configuration": {}
  },
  "Humidity": {
    "Provider": "MockHumidityProvider",
    "Configuration": {}
  }
}

Providers

The communication with specific IoT sensors is implemented through providers, which implement the OpenMts.EnvironmentReader.IEnvironmentFactorProvider interface. The configuration allows to specify providers for one or both of the enviropnmental factors by setting it's name in the Provider field, and add provider-specific configuration options in the matching Configuration object.

Currently available providers:

Provider Factor Device
MockTemperatureProvider temperature none
MockHumidityProvider humidity none

MockTemperatureProvider

Generates mock temperature data for testing purposes.

MockHumidityProvider

Generates mock humidity data for testing purposes.
