Bluetooth Oximeter is used in hospitals, clinics and the Bluetooth low-power fingertip pulse Oximeter is home-based. They can accurately measure the patient's blood oxygen saturation (SpO2), pulse rate (PR) and blood perfusion index (PI). The blood oxygen saturation index is an important physiological parameter that reflects the respiratory cycle, and the blood perfusion index is the measurement data of the blood flow volume flowing through the small blood vessels of the limbs.

The Bluetooth oximeter is based on MindMotion’s MM32W0130 microcontroller:

- Cortex-M0 operating at a frequency of up to 72MHz, allows blood oxygen saturation signal acquisition, algorithm operation and OLED display operation

- Provide low-latency and low-power Bluetooth function and connect to personal smartphones or tablets with Bluetooth 4.0 (or above)

- The fingertip oximeter uses two AAA alkaline batteries and can support up to 36 hours of continuous working time which is attributed to the ultra-lower power consumption of BLE5.0

- Support the automatic switch on/off function when inserting and removing the fingertip oximeter
