Module13.2 ECG is a heart rate measurement module capable of being used for human heart rate statistics and ECG waveform generation. Electrocardiography (ECG) is a technique that uses an electrocardiograph to record the electrical activity of the heart during each cardiac cycle from the body surface. On the signal acquisition side, the Module13.2 ECG integrates the AD8232 single-lead heart rate monitoring front end. The collected ECG signal is processed through the AD8603 low-pass filter, then fed into a 10-bit ADC (AD7476) for analog-to-digital conversion and input into an STM32 (which has a built-in heart rate statistics algorithm) for signal analysis. Finally, the processing results are output in serial communication format, making it easy for the host device to acquire and display the data. In terms of signal output, it adopts a full isolation design between the front-end and the digital part to enhance stability and safety.
Note
Power Supply Note
This product only supports 5V power input. Please strictly follow this power input standard when using the product to avoid damage to the device or potential injury.
Features
ADI integrated front-end (High signal gain G=100, with DC blocking capability)
Serial data output
Built-in heart rate statistics algorithm
Full isolation between front-end and digital section
When using the PC heart rate reading tool, the device needs to be flashed with the serial port transparent transmission firmware (before uploading, please change the serial port initialization pins to the actual connection pins), and the data will be forwarded to the PC.
