HUMAN MEASUREMENT

The PPG Measurement, ECG
and EDA Measurement sections provide a brief guide on using the
EVAL-ADPD7000Z for human measurement. The example wave-
forms in these sections are for reference only and do not illustrate
the performance of the system. The detailed characteristics relate
to the configuration and measurement environment.

PPG MEASUREMENT

The user can place a finger on the light insulation cushion on the
LED and PD pair of the EVAL-ADPD7000Z to get the detailed
PPG signal with the heart rate (see
cushion avoids the light that passes from the LED to the PD.

The user can also place the EVAL-ADPD7000Z on the wrist (PD
and LED side against the skin) to simulate the watch type measure-
ment (see Figure 46).

ECG MEASUREMENT

The EVAL-ADPD7000Z has an integrated electrode board, and
Table 1 explains the connection relationships (see
Figure 55).

For ECG measurement, use the electrode board as shown in
Figure 48 and Figure 49. To obtain the ECG waveform of a human,
use the electrode board on the EVAL-ADPD7000Z. Press the
electrode board placed on the left arm by using the fingers on the
right hand. The right hand fingers are on one side (the side without
the photodiodes and LED pairs) and the left arm is on the other side
(the side with the photodiode and LED pairs).
