The AD8232 ECG Heart Rate Monitor Module is a compact and cost-effective biosignal acquisition module designed for measuring the electrical activity of the heart. It uses the AD8232 integrated circuit to capture and condition small bioelectric signals, producing an analog ECG output that can be read by microcontrollers. The module features built-in high-pass and low-pass filtering to reduce motion artifacts and noise, ensuring stable heart signal monitoring. It supports fitness tracking, portable ECG systems, remote patient monitoring, gaming peripherals, and biomedical signal collection. The module operates within a temperature range of -40°C to 85°C and includes lead-off detection for monitoring electrode connection status. Important pins include +IN, −IN, RLD, OUT, LOD+, LOD−, GND, and +VS for power and signal interfacing.
