Measurement ranges and accuracy
Updated onSeptember 8, 2026
Aidlab 2 records physiological signals from the chest and adds location and electrodermal activity to the measurements available with Aidlab.
Signals and calculated values
| Source | What it measures |
|---|---|
| ECG electrodes | Single-lead ECG; heart rate and beat intervals are derived from the signal |
| Respiration sensor | Changes associated with chest respiration |
| Motion sensors | Movement and body position |
| Skin temperature sensor | Temperature at the sensor's contact with the skin |
| EDA sensor | Skin conductance |
| GNSS receiver | Location |
The app can calculate additional values from supported signals. A value displayed in the app is not necessarily a separate measurement made by a sensor.
Sampling and availability
The signals you receive depend on your device configuration, firmware and software. For integration settings and supported callbacks, use Data types and events and Configuration.
Getting a usable signal
Wear Aidlab 2 correctly and check contact before recording. Movement, loose electrodes and the environment can affect the result. See Low signal quality.
