The SparkFun MAX30105 Particle Sensor is a flexible, powerful sensor enabling sensing of distance, heart rate, particle detection and even the blinking of an eye. The MAX30105 has been equipped with three LEDs as well as a very sensitive photon detector. The idea is to pulse the different LEDs, then detect what shines back. Based on the reflected signature it’s possible to detect different types of particles or materials (such as oxygenated blood or smoke from a fire).
The MAX30105 utilizes a red LED, a green LED, and an IR (Infrared) LED for presence sensing, heart-beat plotting and heart-rate monitoring among its multitude of uses, including Pulse Oximetry. The MAX30105 is designed to operate at 5V and can communicate with both 3.3V and 5V microcontrollers. We’ve also written an Arduino library for the MAX30105 Breakout which takes care of all of the I2C communication, bit shifting, register writing and sample reading.

在SparkFun MAX30105顆粒傳感器的距離，心臟率，粒子探測和眼睛甚至閃爍的靈活，功能強大的傳感器使傳感。該MAX30105已經配備了三個LED，以及一個非常靈敏的光子探測器。我們的想法是脈衝的不同的LED，則檢測什麼閃耀回來。基於該信號簽名返回時，你能告訴不同類型的顆粒或材料（如從火災氧合血或煙霧）的存在下進行。
該MAX30105採用紅色LED，綠色LED，和IR（紅外）LED的存在感，溫度檢測，心臟搏動繪圖和心臟率監測其用途眾人中間，包括脈搏血氧飽和度。該MAX30105可在3.3V運行5V，可與3.3V和5V兩種微控制器進行通信。我們也寫了一個Arduino庫為MAX30105突圍，這需要所有的I 2 C通信的照顧，移位，註冊文字和樣品讀數。
特徵：
- 內置紅，IR和綠色發光二極管
- 5V工作電壓（3.3V是允許的，但綠色LED指示燈不保證經營）
- 板載1.8V調節和I 2 C接口電路
- 感光度可配置到7.81pA
- 3200Hz最大採樣率
- 內置32樣品FIFO（先入先出）
- 應用包括存在檢測，距離傳感（18“最大），脈搏血氧飽和度，血液氧飽和度（SpO2的），煙和顆粒探測
