Protocols

This section describes the used protocols between the three core teams.

Sensors <-> Middleware

For the communication we use a JSON formatted string with the following format.

{
  "version":Integer,
  "sensortype":"String",
  "values":[
    {
      "id":Integer,
      "value":Integer}
  ]
}

Valid values:

• version: Integers beginning with 1 and incremented by 1 with every change.
• sensor: Several valid types [unit]:
  • pressure [gram]
  • temperature [°C]
  • accelerometer [yet not confirmed] possible:[deg/s]
  • microphone [yet not confirmed] possible:[dB]
  • distance_sensor [cm]
• values: Array of entries:
  • id: as an integer beginning with 0
  • value: as an integer

Example:

{
   "version":1,
   "sensortype":"pressure",
   "values":[
      {
         "id":0,
         "value":1000
      },
      {
         "id":1,
         "value":1000
      }
   ]
}
