LCD successfully displays heart rate (BMP), water level (%), and water quality (PPM) in real-time. Also, it can remind you if the water is suitable to drink or you have not drink for long time.
Supporting Evidence: Real-time LCD screenshots showing accurate updates of heart rate, water level, and water quality.
