The AD8232 Single-Lead ECG Sensor Module Kit is a cost-effective, fully integrated electrocardiogram (ECG) front-end solution designed for makers, students, and electronics enthusiasts. This professional-grade heart rate monitoring module extracts, amplifies, and filters biopotential signals to deliver clear, accurate cardiac waveform readings for Arduino, Raspberry Pi, and microcontroller projects.

Key Features & Benefits

Superior Signal Quality

  • Advanced Noise Filtering: Integrated two-pole high-pass filter eliminates motion artifacts and electrode half-cell potential interference
  • Clean Analog Output: Three-pole low-pass filter removes high-frequency electrical noise for research-grade signal clarity
  • 80dB Common-Mode Rejection Ratio: Professional-level noise suppression from DC to 60Hz

Easy Integration & Compatibility

  • Universal Microcontroller Support: Works seamlessly with Arduino UNO, Raspberry Pi, ESP32, and 3.3V/5V development boards
  • Plug-and-Play Design: Pre-wired 3.5mm biomedical electrode jack - no soldering required for basic setup
  • Visual Feedback: Onboard LED indicator pulses in rhythm with detected heartbeats

Complete Monitoring Solution

  • Comprehensive Pin Breakout: Access to SDN (shutdown), LO+/LO- (leads-off detection), analog OUTPUT, and power pins
  • Flexible Electrode Configuration: Supports both two-electrode and three-electrode setups via RA (Right Arm), LA (Left Arm), and RL (Right Leg) connections
  • Fast Restore Function: Automatically recovers from signal saturation when reconnecting electrodes
