AD8232 Analog Heart Rate Pulse Sensor (ECG) Kit
SingleLead ECG Monitoring FrontEnd for Arduino
This AD8232 ECG kit enables non-invasive heart activity monitoring by capturing electrical signals from the body and outputting them as analog readings. It's designed for educational projects, fitness monitoring, and biopotential signal acquisition. [citation:1][citation:12]
Integrated Signal Conditioning - Extracts, amplifies, and filters biopotential signals in noisy conditions [citation:11]
Electrode Interface - Includes 3.5mm jack for connecting biomedical pads with RA/LA/RL electrodes [citation:2]
Supply voltage: DC 3.3V [citation:1][citation:2]
The kit typically includes the AD8232 board, electrode cable, and 3 disposable electrode pads [citation:12]
This product is NOT a medical device and is not intended for diagnosis or treatment of any conditions [citation:1][citation:2]

Troubleshooting
No waveform on serial plotter:
- Use dedicated 3.3V power source to reduce USB interference [citation:1]
- Check electrode connection and placement (RA, LA, RL) [citation:2]
Signal noise:
- Unplug laptop charger to reduce power supply interference [citation:1]
- Adjust highpass/lowpass filter settings for application [citation:11]
