Module13.2 ECG is a heart rate measurement module that can be used for human heart rate statistics and the generation of electrocardiogram curves. An electrocardiogram (ECG) is a technology that uses an electrocardiograph to record the electrical activity changes generated by the heart during each cardiac cycle from the body surface. At the signal acquisition end, this Module13.2 ECG module integrates the AD8232 single-lead heart rate monitoring front end. The collected electrocardiogram signal is processed by the AD8603 low-pass filter, and the analog/digital signal is input by the 10-bit ADC (AD7476) to the STM32 (with a built-in heart rate statistical algorithm) for signal analysis. Finally, the processed results are output externally in the form of serial communication, facilitating the acquisition and display by the master control device. In terms of signal output, a front-end/digital full isolation design is adopted to enhance the stability and safety of the device.
Note
Power Precautions
This product only allows 5V power input. Please strictly adhere to this power input standard when using the product to avoid damaging the device or causing harm to the human body.
Features
ADI integrated front-end (high signal gain G=100, with DC blocking capability)
When using the PC heart rate reading tool, the device needs to be flashed with a serial passthrough firmware (before uploading, please change the serial initialization pins to the actual connected pins) to forward the data to the PC.
