Story

AI Food Analyzer (Smart Health Food Scanner) is an AI-powered and sensor-based device designed for home healthcare applications. The device scans food and analyzes nutritional components such as sugar, carbohydrates, protein, fat, calories, and other essential nutrients. Users enter patient information into a mobile app, including age, weight, height, medical conditions (such as diabetes, high blood pressure, or kidney disease), allergies, and dietary requirements. The system uses components such as a camera, NIR (Near Infrared) sensor, spectrometer, ESP32 or Raspberry Pi microcontroller, and an AI-based analysis engine. When food is scanned, the sensors and camera collect data, which is processed by the AI model and compared with the patient's health profile. The device then displays recommendations on the screen or mobile app, indicating whether the food is safe to eat, should be consumed in moderation, or should be avoided. This technology can help people with diabetes, heart disease, obesity, and other health conditions make informed dietary choices and improve their overall health management.
