This Arduino sketch reads and monitors an ECG (Electrocardiogram) signal using an analog input pin (GPIO34) of an ESP32. It also checks for lead-off conditions (whether the ECG electrodes are properly ...

This Arduino sketch reads and monitors an ECG (Electrocardiogram) signal using an analog input pin (GPIO34) of an ESP32. It also checks for lead-off conditions (whether the ECG electrodes are properly ...

In this paper, such a system is proposed by using AD8232 single lead heart beat sensor to extract the ECG signal and pulse sensor to get the BPM. The obtained sensor data are transmitted to the cloud ...

This research introduces a monitoring system for Electrocardiogram (ECG) using a smartphone. The system uti-lizes an ESP32 microcontroller and an AD8232 sensor to acquire ECG signals and transmit them ...
