# get

### iot.get

Returns a specified IoT measurement value.

### Input Parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| **name** | Text | Yes | Target measurement name |
| **[default]** | Any | No | Default value to use if value doesn't exist |
| **[deviceId]** | Text | No | Source IoT device identifier |

### Returns

Type: **Any**

Returns the specified measurement value or **null** if it does not exist or is empty.

If a **default** value is specified and the measurement doesn't exist, then the default value is returned as the value. This offers a simple way to avoid checking if a measurement exists before retrieving it.

          Note

          

The underlying data type of the returned value is determined when a measurement is captured from a source IoT device.

### Examples

```
// get bpm measurement value
// returns null if doesn't exist
var bpm = iot.get("bpm");
```

```
// get bpm measurement value
// returns a default value of 80 if doesn't exist
var bpm = iot.get("bpm", 80);
```

### Remarks

For object types that support it, multiple values are separated using the pipe '|' character between each value.
