# AWS::IoTFleetWise::Campaign SignalInformation
<a name="aws-properties-iotfleetwise-campaign-signalinformation"></a>

Information about a signal.

## Syntax
<a name="aws-properties-iotfleetwise-campaign-signalinformation-syntax"></a>

To declare this entity in your Amazon CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-iotfleetwise-campaign-signalinformation-syntax.json"></a>

```
{
  "[DataPartitionId](#cfn-iotfleetwise-campaign-signalinformation-datapartitionid)" : String,
  "[MaxSampleCount](#cfn-iotfleetwise-campaign-signalinformation-maxsamplecount)" : Number,
  "[MinimumSamplingIntervalMs](#cfn-iotfleetwise-campaign-signalinformation-minimumsamplingintervalms)" : Number,
  "[Name](#cfn-iotfleetwise-campaign-signalinformation-name)" : String
}
```

### YAML
<a name="aws-properties-iotfleetwise-campaign-signalinformation-syntax.yaml"></a>

```
  [DataPartitionId](#cfn-iotfleetwise-campaign-signalinformation-datapartitionid): String
  [MaxSampleCount](#cfn-iotfleetwise-campaign-signalinformation-maxsamplecount): Number
  [MinimumSamplingIntervalMs](#cfn-iotfleetwise-campaign-signalinformation-minimumsamplingintervalms): Number
  [Name](#cfn-iotfleetwise-campaign-signalinformation-name): String
```

## Properties
<a name="aws-properties-iotfleetwise-campaign-signalinformation-properties"></a>

`DataPartitionId`  <a name="cfn-iotfleetwise-campaign-signalinformation-datapartitionid"></a>
The ID of the data partition this signal is associated with.  
The ID must match one of the IDs provided in `dataPartitions`. This is accomplished either by specifying a particular data partition ID or by using `default` for an established default partition. You can establish a default partition in the `DataPartition` data type.  
If you upload a signal as a condition for a campaign's data partition, the same signal must be included in `signalsToCollect`.
