<a name="iot-moisture-policy"></a>

Buat AWS IoT kebijakan yang memungkinkan Raspberry Pi Anda terhubung dan mengirim pesan AWS IoT.

1. Di [AWS IoT konsol](https://console.aws.amazon.com/iot), jika tombol **Mulai** muncul, pilih. Jika tidak, di panel navigasi, perluas **Keamanan**, lalu pilih **Kebijakan**.

1. Jika kotak dialog **Anda belum memiliki kebijakan apa pun** muncul, pilih **Buat kebijakan**. Jika tidak, pilih **Buat**.

1. Masukkan nama untuk AWS IoT kebijakan (misalnya,**MoistureSensorPolicy**).

1. Di bagian **Tambah pernyataan**, ganti kebijakan yang ada dengan JSON berikut. Ganti {{region}} dan {{account}} dengan Akun AWS nomor AWS Region dan Anda.
