Module13.2 ECG is a heart rate measurement module that can be used for human heart rate statistics and electrocardiogram (ECG) curve generation. The ECG is a technique that uses an electrocardiograph to record the electrical activity changes of the heart during each cardiac cycle from the body surface. On the signal acquisition side, this Module13.2 ECG module integrates the AD8232 single-lead heart rate monitoring front-end. The collected ECG signals are processed by the AD8603 low-pass filter, and the analog/digital signal is input to the STM32 (with built-in heart rate calculation algorithm) via a 10-bit ADC (AD7476) for signal analysis. Finally, the processed results are output in the form of serial communication, making it easy for the main control device to acquire and display the data. The signal output adopts a front-end/digital full-isolation design, enhancing 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.
