It combines red and infrared LEDs with a photodetector and low-noise analog processing to provide reliable SpO2 and heart rate data. Commonly used in fitness wearables, medical monitoring devices, and IoT health projects.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply Voltage\u003c\/td\u003e\n\u003ctd\u003e1.8V core \/ 3.3V or 5V module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLED Wavelengths\u003c\/td\u003e\n\u003ctd\u003e660nm (Red), 880nm (IR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication\u003c\/td\u003e\n\u003ctd\u003eI2C (address 0x57)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e15.5mm x 15.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeart Rate Range\u003c\/td\u003e\n\u003ctd\u003e30–220 bpm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpO2 Range\u003c\/td\u003e\n\u003ctd\u003e70–100%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBuild a wearable fitness tracker with OLED display\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/kit-heart-rate-and-spo2-health-monitor\"\u003eCreate a SpO2 monitor for health screening\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eDevelop a remote patient monitoring system using ESP32\u003c\/li\u003e\n\u003cli\u003eDesign a bio-feedback device for stress management\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThe MAX30102 communicates via I2C and works with any 3.3V microcontroller. Directly compatible with Arduino, ESP32, Raspberry Pi, and STM32 boards. For 5V Arduino boards, use a logic level converter to protect the sensor's I2C pins.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VIN to 3.3V (or 5V if using a module with built-in regulator), GND to ground, SDA and SCL to the I2C pins. No external pull-ups needed as the module includes them. Place the sensor tightly against the skin, avoiding ambient light interference.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
