The Wellue Bluetooth Pulse Oximeter Fingertip is a compact health monitoring device designed for accurate measurement of blood oxygen saturation and pulse rate. Its lightweight plastic casing houses reliable sensor components, with a clear LED display that shows real-time readings. The unit includes a built-in Bluetooth module for wireless data transmission, allowing users to sync measurements with a companion mobile app.

The package comes with two AAA batteries, a soft carry bag, and a lanyard, making it convenient for daily use or travel. The exterior features a smooth, matte-finish shell that resists fingerprints and minor scratches, contributing to long-term durability. The spring-loaded clip mechanism provides consistent pressure on the fingertip for stable readings without discomfort.

Internal optics utilize dual-wavelength LEDs and a photodetector to capture blood volume changes, ensuring reliable oxygen saturation (SpO2) and pulse rate data. The device operates within a standard measurement range and has been tested for basic accuracy under normal conditions. When paired with the free Wellue app, the oximeter enables users to track historical trends, set alerts for low oxygen levels, and export data for further analysis.

This wireless capability is especially useful for monitoring chronic respiratory conditions, altitude training, or postoperative recovery. The device automatically powers on when a finger is inserted and turns off after removal to conserve battery life. Each set of batteries supports extended use, and the low-power Bluetooth 4.0 module maintains stable connectivity with minimal energy consumption.

The affordability of this pulse oximeter makes it accessible for home healthcare, athletes, and individuals seeking regular wellness checks. Its included accessories—carry bag and lanyard—enhance portability, allowing users to keep it within reach during outdoor activities or clinical settings. While it is not a substitute for medical-grade equipment, it serves as a practical tool for day-to-day awareness of oxygen levels and heart rate, offering reliable performance at a reasonable price point.
