{"title":"MAX30102 Heart Rate Sensor Module","handle":"max30102-heart-rate-sensor-module","url":"/products/max30102-heart-rate-sensor-module","description":"The MAX30102 is an integrated heart rate and pulse oximetry (SpO2) sensor module. It combines red and infrared LEDs, a photodetector, and low-noise analogue electronics in a single package, communicating over I²C. Ideal for wearable health monitors, fitness trackers, and biomedical prototyping.\n\nThe module accepts 3.3–5 V input and draws a maximum of 6 mA. A software-controlled shutdown mode reduces standby current to near zero, making it well-suited for battery-powered applications.\n\nKey Features\n\n\nHeart Rate + SpO2 – Measures pulse and blood oxygen saturation via PPG\n\nDual-Wavelength LEDs – 660 nm (red) and 880 nm (IR) for accurate readings\n\n18-Bit ADC – High-resolution analogue-to-digital conversion\n\nAdjustable Sampling Rate – 50 Hz to 3200 Hz\n\nI²C Interface – Standard two-wire connection to any microcontroller\n\nLow Power – 6 mA max; software shutdown for near-zero standby\n\nInterrupt Pin – Hardware interrupt for real-time event notification\n\n\nSpecifications\n\n\nSensor: Maxim MAX30102\n\nInput Voltage: 1.8–5 V DC\n\nCurrent Draw: 6 mA max\n\nADC Resolution: 18-bit\n\nLED Wavelengths: 660 nm / 880 nm\n\nSampling Rate: 50–3200 Hz\n\nOperating Temperature: −40 to +85 °C\n\nInterface: I²C\n\n\nPinout\n\n\nVIN – Power input (1.8–5 V DC)\n\nSCL / SDA – I²C clock and data\n\nINT – Interrupt output\n\nRD / IRD – Ground for red and IR LEDs\n\nGND – Common ground\n\n\nIdeal For\n\nWearable fitness and health monitors\nBiomedical and SpO2 prototyping\nArduino and Raspberry Pi health-sensing projects\n\n\nPackage Contents\n\n1× MAX30102 Heart Rate and Pulse Oximeter Sensor Module\n","vendor":"Little Bird","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":1230,"title":"Default Title","sku":"LB-LS5540","price":10.35,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":41,"option1":"Default Title"}]}
