Aidlab’s sensors measure your heart’s ECG, respiration rate, attitude and skin temperature every time you use it. The sampling rate and resolution is presented as follow:
| Signal Source | Sampling Rate | Sampling Resolution |
|---|---|---|
| ECG Sensor | 500 Hz | 24-bit |
| Respiration Sensor | 30 Hz | 24-bit |
| 9-Axis Motion Sensor | 30 Hz per axis | 10-bit |
| Skin Temperature Sensor | 0.1 Hz | 10-bit |
Aidlab’s ECG and respiration monitor tracks the electric work of the heart and lungs. These precise measurements can be influenced by several external conditions that you should consider when starting a measurement:
Dry skin. Aidlab was made to fight this obstacle, but there can be some unreadable signals if your skin is too dry and will not conduct electricity. Air is not as good conductor as water.
Other devices. Holding other electronic devices connected to electricity or being close to the source of a magnetic field will strongly influence Aidlab’s readings. Remember that your heart signal is weak compared to the signal collected from a hairdryer.
No skin contact. To collect proper readings, electrodes should touch the chest. Aidlab will have problems measuring ECG or respiration rate if there is something - like hairs - between the sensor and the chest. Any dirt or mud will also influence the measurement.
