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