MAX30100 Pulse Oximeter and Heart Rate Sensor Module (SpO₂/BPM)

Overview: High-Precision Biometric Monitoring

The MAX30100 Pulse Oximeter and Heart Rate Sensor Module is a fully integrated biosensor solution designed specifically for wearable health applications. It combines two internal LEDs (Red and Infrared), a photodetector, and a low-noise analog signal processing unit to accurately detect heart rate and blood oxygen saturation (SpO₂).

For advanced projects in the Bangladeshi tech sector—such as smartwatches, fitness trackers, and remote patient monitoring—the MAX30100 offers trusted, clinical-grade accuracy. It uses a non-invasive optical method, shining light through the fingertip to measure the absorbance of pulsing blood. Its advanced features, including Ambient Light Cancellation (ALC) and high Signal-to-Noise Ratio (SNR), ensure stable and accurate readings even with movement.

Crucially, the module features ultra-low power operation (with negligible standby current), making it the optimal choice for battery-powered, long-duration wearable devices.
