Sensor Reference
Detailed documentation for each sensor available in mindLAMP. Every page covers data fields and JSON schema, platform support, sampling behavior, Cortex features, and configuration options.
Every sensor has a unique SensorSpec identifier used in the API and data events. For the general event structure shared by all sensors, see Sensor Data Format.
Device Sensors
| Sensor | SensorSpec | Platform | Sampling | Cortex |

Health Platform Sensors
These sensors read from Apple HealthKit (iOS) or Google Health Connect (Android) and typically require a connected wearable device.
| Sensor | SensorSpec | Cortex |

| Sleep | lamp.sleep | Yes |
| Heart Rate | lamp.heart_rate | — |
| Heart Rate Variability | lamp.heartratevariability_sdnn | — |
| Respiratory Rate | lamp.respiratory_rate | — |
| Blood Pressure | lamp.blood_pressure | — |
| Blood Glucose | lamp.blood_glucose | — |
| Oxygen Saturation | lamp.oxygen_saturation | — |
| Body Temperature | lamp.body_temperature | — |
| Workouts | lamp.segment | — |
| Nutrition | lamp.nutrition | — |
iOS SensorKit
On enrolled iOS research devices, Apple's SensorKit framework provides additional data streams — including app usage, phone call metadata, text message metadata, and location visit categories. These are not standard mindLAMP sensors (they have no lamp.* SensorSpec) but are consumed by Cortex as raw features and feed into several secondary features (e.g., screen_unlocks, app_time, text_number, visit_time). SensorKit requires explicit enrollment approval from Apple.
