TechREQ

Description In order to send sensor data over TTN, a binary format has to be defined for the serialization.

The binary serialized data shall be handled by protobuf environment. The following protobuf format description shall apply:

syntax = "proto2";

message dustSensorMeasurement {
    required float particularMatter2_5um  = 1;
    required float particularMatter10um   = 2;
    required float temperature            = 3;
    required float humidity               = 4;
}

Rationale

format has to be binary because the bandwidth of the LoRaWan channel is too restricted to do a serialization using JSON or XML formats
an overal definition has to be available so the receiving system can de-serialize the data
