Meter data in Laravel framework

I have problems with Laravel framework.

My problem is that for some reason, when I try to put data in a way, they are not sent and send a 404 "page not found" error.

This is the code I have.

web (In the routes folder):

<?php

Route::get('/', function () {
return view('welcome');
 });

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');
Route::post('/home/sendData', 'HomeController@sendData')->name('home/sendData');

HomeController (In the controllers folder):

public function index()
{
    return view('home');
}
public function sendData(Request $request){
    $this->validate($request, [
        'nombre'    =>  'required',
        'precio'     =>  'required',
        'empresa'     =>  'required'
    ]);

    $product = new product([
        'nombre'    =>  $request->get('nombre'),
        'precio'     =>  $request->get('precio'),
        'empresa'     =>  $request->get('empresa')
    ]);
    $product->save();
    return redirect()->route('home')->with('success', 'Data Added');
}

home.blade (In the views folder):

@extends('layouts.app')

@section('content')
<div class="container">
<div class="row justify-content-center">
    <div class="col-md-8">
        <div class="card">
            <div class="card-header">Dashboard</div>

            <div class="card-body">
                @if (session('status'))
                    <div class="alert alert-success" role="alert">
                        {{ session('status') }}
                    </div>
                @endif

                Has iniciado sesion
             </div>
         </div>
     </div>
   </div>
 </div>

<div class="row">
<div class="col-md-12">
<br />
<h3>Meter datos del producto</h3>
<br />
<form method="post" action="{{url('home')}}">
{{csrf_field()}}
<div class="form-group" align="center">
<input type="text" name="nombre" class="form-control" placeholder="Coloque el nombre del producto" />
</div>
<div class="form-group" align="center">

</div>
<div class="form-group" align="center">

</div>
<div class="form-group" align="center">

</div>
</form>
</div>
</div>
