Arnav studied the causes and effects of asthma and came up with the AsthmaPi which uses a Raspberry Pi, a Sense Hat, an MQ-135 Gas Sensor, a Sharp Optical Dust Sensor and an Arduino Uno. It is programmed in Python and C++ and triggers email and SMS text message alerts to take medication and remind patients to go for review visits. There is also an accompanying booklet which describes the condition and how to treat it. The sensors on the SenseHAT are used to measure temperature and humidity and the MQ gas sensor detects smoke, nitrogen compounds and host of other airborne triggers.
