 PythonSensor
 ============
 
-Use the :class:`~airflow.sensors.python.PythonSensor` to use arbitrary 
callable for sensing. The callable
-should return True when it succeeds, False otherwise.
+A PythonSensor waits for a certain condition to be ``True``, for example to 
wait for a file to exist. The
+PythonSensor is available via ``@task.sensor`` and 
``airflow.sensors.python.PythonSensor``. The callable
+should return a boolean ``True`` or ``False``, indicating whether a condition 
is met. For example:
 
-.. exampleinclude:: /../../airflow/example_dags/example_sensors.py
-    :language: python
-    :dedent: 4
-    :start-after: [START example_python_sensors]
-    :end-before: [END example_python_sensors]
+.. code-block:: python
+
+    import datetime
+
+    from airflow.decorators import dag, task
+    from airflow.sensors.python import PythonSensor
+
+
+    @dag(start_date=datetime.datetime(2023, 1, 1), schedule=None)
+    def example():
+        @task.sensor
+        def wait_for_success():
+            return datetime.datetime.now().minute % 2 == 0
+
+        wait_for_success()
+        PythonSensor(task_id="wait_for_even_minute", 
python_callable=wait_for_success)

Review Comment:
   I tested on 2.5.1 and it just works:

   I could split this into separate functions because it does look a little odd 
to reference a taskflow-decorated function from a PythonSensor class?
