View AllClose
- Working Principle: Based on the PPG principle, it emits 660nm red light and 880nm infrared light to illuminate human tissue, detects the change in light signal intensity after reflection or transmission, calculates blood oxygen saturation by analyzing the change in light signal, and calculates heart rate by periodic changes in pulse wave
- High Integration: Integrates LED emitter, photodiode, AFE analog front end and DSP digital processing circuit, built-in 1.8V and 3.3V LDO voltage regulator circuit, can be directly powered by 5V without additional power management
- High Precision: 18-bit ADC converter, red light (660nm) and infrared light (880nm) dual wavelength design, programmable sampling rate (up to 3.2kHz), providing high-precision heart rate and blood oxygen data
- Easy to Use: Standard I2C interface (400kHz), compatible with mainstream microcontrollers, built-in 32-depth FIFO cache, reducing the master control resource usage
- Usage Scenarios: Wearable devices such as smart watches and fitness bracelets; pulse oximetry monitoring for home use; real-time monitoring of heart rate and blood oxygen during training; PPG pulse wave research, biosignal collection experiments, etc
