Sensor Systems for the Monitoring of Personal Health and Lifestyle
Management
Project Goals
• Survey of commercial sensors and sensor systems. • Sensor system on Windows Mobile OS.
• Design• Implement • Demonstrate
Overview
Asthma – One of The Most Common Lung Diseases
150,000,000 Asthma patients around the world!!!
10% of them needs to use peak flow meter to help treatment
Traditional Peak Flow Meter – Very Limited Functions
Usually just the measurement values and the streetlight system.
• Streetlight system.
• Green – Good• Yellow – Caution!• Red – Emergency
SMPL System
Our System
• Requirements.• Wear-ability.• Non-obtrusiveness.• Ease of use (preferably).• Wireless communication.• Power consumption / lifetime.• Applicable for monitoring on a mobile phone.
PeakSoft
• Goals• User friendly.• Overview of personal health.
• Advantage in the commercial market• Utilizes the mobile phone.• Aimed for personal use.
Digital Peak Flow Meter
• Integrate existing peak flow meter.• AM1+ BT.
• Uses the phone to send results.• Did not suit our needs.
• We decided to make our own.• Compare price (vs AM1+ BT).• Customize to our needs.
