Figure 15 shows the application of the ECG sensor in combination with the Assembled Core
(left), the Plugged (middle), and the Board (right). The two measuring electrodes (IN +/-) were
placed on the collar bones and the reference electrode on the iliac crest to receive the signal
of the Einthoven LeadI. Please see the ECG Sensor Datasheet for more information regarding
the ECG signal.
