**To get information about a detector model**
The following ``describe-detector-model`` example displays details for the specified detector model. Because the ``version`` parameter is not specified, information about the latest version is returned. ::
aws iotevents describe-detector-model \
--detector-model-name motorDetectorModel
Output::
