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.
