# Get one Sensor

> Retrieve a single Sensor record by its Id.

A **Sensor** represents a physical IoT sensor deployed in a location for monitoring environmental conditions or occupancy. Sensors can detect presence, count people, measure temperature, humidity, noise, CO2 levels, and other metrics.

## Authentication

<Note>
  This endpoint requires OAuth2 authentication. Include a valid bearer token in the `Authorization` header.
  The authenticated user must be a full unrestricted administrator or have the **`Sensor-Read`** role.
</Note>

## Path Parameters

<ParamField path="id" type="integer" required>
  The Id of the Sensor record to retrieve.
</ParamField>

## Code Examples

<CodeGroup>
  ```bash cURL theme={null}
  curl -X GET \
    "https://spaces.nexudus.com/api/sys/sensors/87654321" \
    -H "Authorization: Bearer YOUR_TOKEN"
  ```

  ```javascript JavaScript theme={null}
  const response = await fetch(
    'https://spaces.nexudus.com/api/sys/sensors/87654321',
    {
      headers: {
        'Authorization': 'Bearer YOUR_TOKEN'
      }
    }
  );

  const record = await response.json();
  ```

  ```python Python theme={null}
  import requests

  response = requests.get(
      'https://spaces.nexudus.com/api/sys/sensors/87654321',
      headers={
