Generic مستشعر نبضات القلب 2A2 MAX30102 RCWL0531

Small size, Low power consumption, I2C interface, Green board PCB, Ambient light rejection, Integrated heart rate and SpO2 algorithms

Instructions for Use: 1. Wiring: Connect I2C (SDA, SCL) to microcontroller (e.g., A4, A5), INT to a digital pin (e.g., D2), VCC to 3.3V, and GND to GND. Ensure I2C lines are pulled up to 3.3V with a resistor. 2. Software: Install 'SparkFun MAX3010X Pulse and Proximity Sensor Library' via Arduino Library Manager. Include necessary libraries in your code. 3. Operation: Place your index finger on the sensor with steady pressure. 4. Troubleshooting/Warnings: If 'MAX30105 was not found', check wiring/power. If IR value is low (<50000), it may indicate 'No finger?'.
