# Step 1: Create the AWS IoT policy


Create an AWS IoT policy that allows your Raspberry Pi to connect and send messages to AWS IoT.

1. In the [AWS IoT console](https://console.aws.amazon.com/iot), if a **Get started** button appears, choose it. Otherwise, in the navigation pane, expand ** Security**, and then choose **Policies**.

1. If a **You don't have any policies yet** dialog box appears, choose **Create a policy**. Otherwise, choose **Create**.

1. Enter a name for the AWS IoT policy (for example, **MoistureSensorPolicy**).

1. In the **Add statements** section, replace the existing policy with the following JSON. Replace *region* and *account* with your AWS Region and AWS account number.
