Wireless Spirometer

Overview

A spirometer is a device designed to measure the volume of air inhaled and exhaled by the lungs. It is essential for assessing and improving lung health, especially for individuals with COPD, asthma, allergies, or other respiratory conditions. These measurements are crucial for the early detection of health anomalies and for training the lungs to overcome breathing challenges.

This wireless spirometer tracks key lung health indicators, including FEV1, peak flow (L/min), total lung capacity, and detailed inhalation/exhalation patterns over time. With seamless connectivity to a user-friendly GUI via Bluetooth® or Wi-Fi, it enables real-time monitoring and easy data sharing with medical professionals. NFC charging ensures a fully wireless and hassle-free experience.

System Benefits:

  • Bluetooth and Wi-Fi support for secure data transfer, storage, and remote evaluation, ensuring accessibility for both users and healthcare providers.
  • Flexible charging options for the integrated Li-ion battery via USB or NFC Wireless Charging (WLC).
