# SRPhotoplethysmogramOpticalSample.Condition

The conditions that may occur when recording photoplethysmogram optical data.

```
struct Condition
```

## Topics

### Getting the condition

[`static let signalSaturation: SRPhotoplethysmogramOpticalSample.Condition`](/documentation/SensorKit/SRPhotoplethysmogramOpticalSample/Condition/signalSaturation)

The signal exceeds the measurement capacity of the sensor.

[`static let unreliableNoise: SRPhotoplethysmogramOpticalSample.Condition`](/documentation/SensorKit/SRPhotoplethysmogramOpticalSample/Condition/unreliableNoise)

The signal noise is unreliable.

### Initializing a condition

[`init(rawValue: String)`](/documentation/SensorKit/SRPhotoplethysmogramOpticalSample/Condition/init(rawValue:))

Initializes a condition structure.
