Pulse Oximeter and Heart-Rate Sensor IC 14-Pin OLGA
Hi, fellas. Welcome back to the new post today. MAX30100 is a Pulse Oximeter and Heart-Rate Sensor IC which is used to check the health of a person with any condition that affects blood oxygen levels. This article mainly introduces specification, pinout, datasheet, and other detailed information about Maxim Integrated MAX30100.
MAX30100EFD
MAX30100 is a Pulse Oximeter and Heart-Rate Sensor IC which is used to check the health of a person with any condition that affects blood oxygen levels, such as Heart Attack, Heart failure, Lungs Cancer Asthma, etc.
The MAX30100 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.
The sensor comprises two Light Emitting Diodes, a photodetector, and a series of low noise signal processing devices to detect heart rate and to perform pulse oximetry.

Interfacing Max30100 Pulse Oximeter Sensor with Arduino Circuit Diagram
First, let's start with a very basic circuit diagram. As you can see the VIN and GND pins of the Max30100 sensor are connected with the Arduino’s 3.3v and GND pins. The SCL pin is connected with the Analog pin A5, SDA pin is connected with the Analog pin A4. While the INT pin is not connected.
Interfacing Max30100 Pulse Oximeter Sensor and 16×2 LCD with Arduino Circuit Diagram
This is the modified circuit diagram. The max30100 pulse Oximeter sensor connection with the Arduino remains the same. This time I added a 16×2 LCD. As you can see, pin number 1 and pin number 16 are connected with the Arduino’s ground. Pin number 2 and pin number 15 are connected with the Arduino’s 5 volts. Pin number 3 is the contrast pin and is connected with the middle leg of the potentiometer this is used for the LCD contrast adjustment.
The RS pin of the LCD is connected with the Arduino’s pin number 9, the R/W pin is connected with the ground, Enable pin is connected with the Arduino’s pin number 8. Pins D4 to D7 of the 16X2 LCD is connected with the Arduino’s pins 7, 6, 5, and 4.
