Non-Invasive Glucometer with TFT Screen monitoring with Audio and vibration Alerts https://www.hvstechnologies.in/product/hvs-4763-non-invasive-glucometer-with-tft-screen-monitoring-with-audio-and-vibration-alerts/ https://www.hvstechnologies.in/product/hvs-4763-non-invasive-glucometer-with-tft-screen-monitoring-with-audio-and-vibration-alerts/#respond Sat, 16 May 2026 13:18:21 +0000 https://www.hvstechnologies.in/?post_type=product&p=21685 This project presents a real-time, non-invasive glucose monitoring system using an Arduino microcontroller, a TFT display, a DF Player Mini audio module, and a vibration motor to provide multimodal feedback. A non-invasive glucose sensor measures glucose levels, which are displayed on a TFT screen with color-coded indications: blue for low, green for normal, and red for high glucose levels. Additionally, a speaker announces the glucose measurement aloud, enhancing accessibility. A vibration motor provides haptic feedback—intermittent vibrations for low glucose, no vibration for normal, and a long vibration for high glucose. This system enhances user awareness through visual, auditory, and tactile cues, making glucose monitoring more intuitive, user-friendly, and comfortable without the need for finger pricking.

 

 

Objectives:

  1. Display Glucose Levels Clearly –Show glucose readings on a TFT screen with color codes:
  • Blue for low
  • Green for normal
  • Red for high
  1. Read Glucose Aloud –Use a speaker (DFPlayer Mini) to announce the glucose level.
  2. Provide Vibration Alerts –Use a vibration motor for alerts:
  • Intermittent vibrations for low glucose
  • No vibration for normal
  • Long vibration for high glucose
  1. Make It Easy to Use –Replace the LCD with a TFT screen for better visibility.
  2. Ensure Portability –Use Arduino and compact components for an efficient and portable design.
