# NMEA
[NMEA (National Marine Electronics Association) 0183](https://en.wikipedia.org/wiki/NMEA_0183) is a standard for parsing sensor data for many marine electronics like echo sounders, sonars, anemometers, gyrocompasses, autopilots and GPS receivers.
Example GPS data looks like this:
```bash
cat /dev/ttyACM0
```
```

Every line starts with a dollar sign. The next 2 characters is the "talker", followed by 3 characters for the "type" of record. It is followed by a CSV and then a "*" followed by a checksum.
Tested with a [ublox series 6 GPS receiver](https://www.u-blox.com/en/product/neo-6-series).
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `nmea` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:nmea, "~> 0.1.0"}
]
end
```
Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
be found at [https://hexdocs.pm/nmea](https://hexdocs.pm/nmea).
