Max30100 Heart Rate Sensor Pulse Sensor

MAX30100 Heart Rate and SpO2 Sensor – Pulse and Oxygen Monitoring for IoT and Health Projects

The MAX30100 is a compact and low-power sensor module that combines two essential health parameters: heart rate (pulse) and blood oxygen saturation (SpO2). It uses infrared (IR) and red LEDs with a photodetector to measure changes in blood volume, making it ideal for wearable devices, health monitoring systems, and IoT-based medical projects.

This sensor communicates via the I2C protocol, making it easy to interface with Arduino, ESP32, ESP8266, and other microcontrollers. It’s widely used in student projects and prototype health devices across Bangladesh.

Key Features:

• Measures: Heart rate (BPM) and SpO2 (blood oxygen level)

• Interface: I2C (SCL, SDA)

• Operating Voltage: 1.8V to 5V (with onboard regulator)

• Onboard IR and red LEDs

• Low power consumption for wearable use

• Compact size for easy integration

• Compatible with Arduino, ESP32, Raspberry Pi, etc.

Applications:

• Health monitoring systems

• Smartwatches and wearable fitness devices

• IoT-based patient monitoring

• Biomedical research projects

• Academic electronics projects in Bangladesh (EEE/CSE)

The MAX30100 sensor is a cost-effective and reliable solution for building real-time health tracking systems in both hobby and professional applications.
