MAX30102 Heart Rate and Pulse Oximeter Sensor Module (Black)

The MAX30102 Heart Rate and Pulse Oximeter sensor module (black board) is built around the MAX30102 optical sensor, which combines red and infrared LEDs, a photodetector and signal processing in one chip. Place a fingertip on the sensor and it measures the light reflected back with each heartbeat, which a microcontroller turns into heart rate and blood-oxygen (SpO2) estimates. It connects over I2C to Arduino, ESP32 and Raspberry Pi boards.

• 1 × MAX30102 heart rate and pulse oximeter sensor module (black)

Tip: Start with a ready-made library such as the SparkFun MAX3010x library for Arduino. Rest your finger lightly and keep it still, because pressure and movement change the readings. This module is for learning and prototyping, not for medical diagnosis.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
