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.
Integrated Signal Conditioning - Extracts, amplifies, and filters biopotential signals in noisy conditions
Electrode Interface - Includes 3.5mm jack for connecting biomedical pads with RA/LA/RL electrodes
Supply voltage: DC 3.3V
The kit typically includes the AD8232 board, electrode cable, and 3 disposable electrode pads
This product is NOT a medical device and is not intended for diagnosis or treatment of any conditions

- Bioelectricity signal acquisition projects
Easy Arduino Integration - Connect OUTPUT to A0, 3.3V to 3.3V, and GND to GND
Versatile Use - View ECG waveform via Arduino Serial Plotter or oscilloscope
√ Includes electrode cable and disposable pads
√ Compatible with Arduino, ESP32, and Raspberry Pi
√ Widely supported with sample code and documentation
= Troubleshooting =
No waveform on serial plotter:
- Use dedicated 3.3V power source to reduce USB interference
- Check electrode connection and placement (RA, LA, RL)
Signal noise:
- Unplug laptop charger to reduce power supply interference
- Adjust highpass/lowpass filter settings for application
