INTEGRATED PORTABLE WATER PURIFICATION AND COLORIMETRIC DIAGNOSTICS SYSTEM WITH PASSIVE WIRELESS READING VIA NFC

Abstract

The present invention relates to a portable, integrated water purification and colorimetric diagnostic system capable of performing passive wireless readings using NFC technology, without the need for a battery or external power source. The device combines a multi-layer filtration module with a colorimetric analysis chamber and an NFC tag with an integrated optical sensor, which allows for the digital transmission of the result when a reader or mobile phone is brought close to it. This solution provides a compact, economical, and environmentally friendly alternative to traditional purification and diagnostic systems, offering portability, precision, and complete autonomy, making it ideal for use in rural areas, emergencies, or environmental monitoring education programs.
