# Buoys & Sensors

## Buoys

There are two types of Nemo Pi Buoys - **Mooring Buoys** and **Smart Buoys**.

* **Mooring Buoys** are buoys you can anchor rather than damaging the reefs below.
* **Smart Buoys** are not for anchoring, but instead come with sensors that can perform a variety of data collection and monitoring tasks.

Both types of buoys will show up on your organization dashboard and can be monitored.

## Sensors

{% hint style="success" %}
**Applies to Nemo Pi Smart Buoys**

Sensors are only available on Nemo Pi Smart Buoys, not Mooring Buoys.
{% endhint %}

Sensors only apply to smart buoys and are what enable data collection. Customise sensors to change what sort of data you are collecting. See our growing list of [supported sensors](/fundamentals/buoys-and-sensors/supported-sensors.md).
