SparkFun SEN-16474 Particle Sensor Breakout Board
SparkFun SEN-16474 MAX30101 Particle Sensor Board is a flexible, powerful sensor enabling sensing of distance, heart rate, particle detection, and even the blinking of an eye. The MAX30101 has three LEDs and a very sensitive photon detector. The idea is to pulse the LEDs and 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 MAX30101 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 MAX30101 is designed to operate at 5V and can communicate with 3.3V and 5V microcontrollers. An Arduino library for the MAX30101 Breakout takes care of all of the I2C communication, bit shifting, register writing, and sample reading.
Features
- Built-in red, IR, and green LEDs
- 5V operation (3.3V is allowed, but green LED is not guaranteed to operate)
- Onboard 1.8V regulation and I2C interface circuitry
- Down to 7.81pA sensitivity configurable
- 3200Hz maximum sample rate
- Built-in 32 sample FIFO (First In, First Out)
Applications
- Presence detection
- Distance sensing (18" max)
- Pulse oximetry
- Blood oxygen saturation level (SpO2)
- Smoke and particle detection
