Generic 2A9 GY-MAX30100 Heart Rate Click Sensor

Product description

Description The sensor is an integrated pulse oximetry and heart rate monitor sensor solution.

It combines two LED’s, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse and heart-rate signals.

It operates from 1.8V and 3.3V power supplies and can be powered down through software with negligible standby current, permitting the power supply to remain connected at all times.

Features 1. Consumes very little power (operates from 1.8V and 3.3V) 2. Ultra-Low Shutdown Current (0.7µA, type) 3. Fast Data Output Capability 4. Interface Type: I2C Displaying MAX30100 SpO2 &amp

BPM Value on LCD Display Now let us use the 16X2 LCD Display to see the value of BPM &amp

SpO2 instead of Serial Monitor.

Assemble the circuit as per the circuit diagram below.

Connect the Vin pin of MAX30100 to Arduino 5V or 3.3V pin, GND to GND.

Connect the I2C Pin, SCL &amp

SDA of MAX30100 to A5 &amp

A4 of Arduino.

Similarly connect the LCD pin 1, 5, 16 to GND of Arduino and 2, 15 to 5V VCC.

Similarly connect LCD pin 4, 6, 11, 12, 13, 14 to Arduino pin 13, 12, 11, 10, 9, 8. Use 10K Potentiometer at pin 3 of LCD to adjust the contrast of LCD.
