Added to your shopping cart

Maxim Integrated MAX30101 Pulse Oximeter and Heart-Rate Sensor is an integrated pulse oximetry and heart rate monitor module for fitness and healthcare. This device includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30101 provides a complete system solution to ease the design-in process for mobile and wearable devices. The MAX30101 operates from a single 1.8V power supply and a separate 5.0V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.
