ADS1293 3 Channel Heart ECG Monitoring Sensor Module [2.7V-5.5V]

Description:
Electrocardiography is the process of producing an electrocardiogram (ECG), a recording, a graph of voltage versus time, of the electrical activity of the heart using electrodes placed on the skin.
This allows us to understand the level of physiological arousal that someone is experiencing. Medical uses for this information are varied and often need to be combined with knowledge of the structure of the heart and physical examination signs to be interpreted.
The ADS1293 includes all the features typically required in portable, low medical consumption, sports and fitness ECG applications.
This module includes 3 high-resolution digital electrocardiograms (ECG) channels with synchronized output stimulation. 
Each channel can be set for a specific sampling frequency and bandwidth, allowing users to optimize their configuration for performance and power consumption. All input pins contain electromagnetic interference (EMI) filter and the input channel can be selected via a flexible routing switch.
The ADS1293 enables the creation of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. While ECG/PPG are ideal measures to track emotional arousal, they are not able to reveal emotional valence, the direction of emotion. The true power of ECG/PPG techniques unfolds as these sensors are combined with other data sources such as facial expression analysis, EEG, and eye-tracking.
The ADS1293 incorporates a self-diagnostics alarm system to detect when the system is out of the 2 applications operating conditions range. Such events are reported to error flags.
