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

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.
