MAX30100 Pulse Oximeter Heart Rate Sensor Module

the max30100 pulse oximeter heart rate sensor module is a biomedical sensing device designed to measure heart rate (pulse) and blood oxygen saturation (spo2) using optical sensing technology. it is widely used in health monitoring systems, wearable devices, fitness trackers, and iot-based healthcare projects.

this module works using a combination of red and infrared leds along with a photodetector. when a finger is placed on the sensor, the leds emit light into the skin, and the reflected light is measured by the photodetector. based on the variation in light absorption caused by blood flow, the module calculates heart rate and oxygen saturation levels.

the sensor communicates using the i2c protocol, which allows easy connection with microcontroller platforms such as arduino, esp32, nodemcu, raspberry pi, and other embedded systems using only a few pins.

the max30100 is designed for low power consumption, making it suitable for battery-powered and portable applications. its compact size allows easy integration into wearable and embedded health monitoring devices.

key features of the max30100 pulse oximeter module include:

• measures heart rate (pulse) and spo2 levels
