Oxygen Saturation (lamp.oxygen_saturation)

Records blood oxygen saturation (SpO2) percentage, typically from a smartwatch with a pulse oximeter sensor.

Configuration

• SensorSpec: lamp.oxygen_saturation
• Sampling: Continuous (events synced from health platform)
• Platform: iOS (HealthKit), Android (Health Connect)
• Typical source: Apple Watch, compatible WearOS watch
• Requirements: Wearable with pulse oximeter; health platform permissions granted

Usage

SpO2 readings are recorded by the wearable (typically during sleep or on-demand) and synced via the health platform.
