{"title":"Gravity: Arduino Heart Rate Monitor Sensor (ECG)","handle":"gravity-arduino-heart-rate-monitor-sensor-ecg","url":"/products/gravity-arduino-heart-rate-monitor-sensor-ecg","description":"The DFRobot Gravity Heart Rate Monitor Sensor measures the electrical activity of the heart and outputs it as an analog signal. Built around the AD8232 chip, it filters and amplifies the ECG signal to produce a clean waveform from the PR and QT intervals — viewable in real time using the Arduino IDE's Serial Plotter.\n\nThe Gravity interface allows plug-and-play connection with compatible Arduino boards and shields. Operating at 3.3–5V, it's also compatible with Raspberry Pi and other 3.3V microcontrollers.\n\nKey Features\n\n\nAD8232 Signal Conditioning – Filters noise to produce a clean ECG waveform\n\nAnalog Output – 0–3.3V output for direct ADC reading\n\nGravity Interface – PH2.0-3P connector for plug-and-play use\n\nWide Voltage Support – 3.3–6V input (5V recommended)\n\nLow Power – Less than 10mA operating current\n\nCompact Size – 35 × 22mm\n\n\nSpecifications\n\n\nInput Voltage – 3.3–6V (5V recommended)\n\nOutput Voltage – 0–3.3V\n\nInterface – Analog (PH2.0-3P)\n\nOperating Current – <10mA\n\nDimensions – 35 × 22mm\n\n\nIdeal For\n\nLearning about ECG signals and heart rate monitoring\nBiometric and health-related maker projects\nArduino and Raspberry Pi sensor experiments\nData visualisation with the Arduino Serial Plotter\n\n\nPackage Contents\n\n1× Heart Rate Monitor Sensor\n1× Sensor cable with electrode pad connector (3-pin)\n6× Biomedical sensor pads\n1× PH2.0-3P cable\n\n\n\nWarning: This product is NOT a medical device and is not intended to be used as such or as an accessory to such, nor to diagnose or treat any conditions.\n\n\nResources\n\nDFRobot Product Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":13667,"title":"Default Title","sku":"DF-SEN0213","price":33.7,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":247,"option1":"Default Title"}]}
