Fermion: MAX30102 Heart Rate and Oximeter Sensor

Q: <h3>"Cannot read or The analog reading is always 0"</h3>

1. Check whether the code wiring is correct; 2. Whether the use method is correct, pay attention to use the strap to tie the module to the finger, and do not press the back of the sensor with your hand; 3. Check whether the plastic film on the sensor is in good condition, without plastic film SEN0203 can not work (it can be replaced by transparent tape)Note:It is recommended to fix the probe on the finger pulp when using the test<figure class="image"><img src="https://dfimg.dfrobot.com/628da052aa9508d63a41e164/makelog/a10a15810e876a86a3b6482e808da6b0_0x0.png.webp"></figure>

1. Example Code for Arduino - Get Heart Rate and Blood Oxygen Data

In this sample, the heart rate and blood oxygen data is obtained through interrupts, and the heart rate is measured when the sensor's red light is on. If the interrupts is shielded, the data can still be obtained, but during the update the data obtained does not change.
