AD8232 ECG Monitor Sensor Module
Description:
AD8232 ECG Monitor Sensor Module is a cost-effective and easy-to-use sensor board designed to measure the electrical activity of the heart (ECG or Electrocardiogram). It is based on the Analog Devices AD8232 IC, which is a highly integrated signal conditioning block for ECG and other biopotential measurement applications.
Features:
1. Based on Analog Devices AD8232 IC for ECG and bio-potential signal processing
2. Capable of measuring heart rate and electrical activity of the heart (ECG)
3. Provides clean, amplified, and filtered analog ECG signal output
4. Integrated operational amplifier for signal conditioning
5. Fast recovery from motion artifacts and signal disruptions
6. Low power consumption suitable for wearable and portable devices
7. Onboard LED indicator for heartbeat detection visualization
8. 3-point ECG connection (RA, LA, RL) for accurate signal capture
9. Easy to interface with Arduino, Raspberry Pi, ESP32, and other microcontrollers
10. Compact and lightweight design for easy integration
11. Built-in right leg drive circuit for improved common-mode rejection
12. High signal quality with reduced noise and motion interference
