The MAX30102 is a heart rate and pulse oximeter sensor module for Arduino, used for detecting pulse and blood oxygen saturation. This module is among the best pulse oximeters in Pakistan for DIY projects and health monitoring applications. Check the price for pulse oximeter online to get it delivered in Pakistan.

Parameters

• LED peak wavelength: 660nm / 880nm
• LED supply voltage: 3.3-5V
• Detection signal type: Optical reflection signal (PPG)
• Output signal interface: I2C interface
• Communication interface voltage: 1.8V / 3.3V / 5V (optional)

Working Principle

The pulse oximeter works using the photolysis method. It measures pulse and blood oxygen saturation by detecting light transmittance changes in human tissue caused by blood vessel pulsation. Specific wavelength LEDs illuminate oxyhemoglobin (HbO2) and hemoglobin (Hb) in arterial blood, and the transmitted light is converted into electrical signals. These signals are amplified and output for monitoring.
