## Under the hood
```
typedef struct __attribute__((packed)) DataReading {
float d;
uint16_t id;
uint8_t t;
} DataReading;
```
Each sensor in the system sends its data over ESP-NOW or LoRa as a float 'd' inside of a structure called a DataReading. Its global sensor address is represented by an integer 'id', and each type of reading is represented by a single byte 't'. If a sensor or gateway needs to send multiple DataReadings, then they are sent in an array. A single DataReading.id may have readings of multiple types ('t') associated with it.
