AD5940 Bio-Electric Shield User Guide
Introduction
The EVAL-AD5940BIOZ shield was designed specifically for carrying out bio-electric measurements. These include:
- Electrodermal Activity (EDA)
- Body Impedance Analysis (4-wire) (BIA)
- Electrocardiogram (ECG)
- Body Impedance Analysis (2-wire) (BIOZ-2Wire)
The platform is an Arduino UNO form factorbase board. This section describes the key features of the board and how to set it up to take measurements.
