Blood oxygen saturation is an important physiological parameter reflecting whether the respiratory function and oxygen content of human body are normal, and whether the tissues of our body are healthy. In recent years, with the outbreak of COVID-19 pandemic and the popularization of medical knowledge, the growing emphasis on monitoring blood oxygen brings about an increasing demand for pulse oximeter in both medical care and household.

The UM32G130 series of Unicmicro is a low-power 32-bit MCU developed based on ARM Cortex-M0+. This IoTP processor features low pin count, wide voltage range and rich peripherals, meeting customer’s needs for solution implementation.
