A wearable necklace indoor air quality detector with a mobile phone display app.
Description
iAir is a wearable necklace air quality detector. It is able to detect temperature and many contaminating gases of low concentrations including CO, alcohol, volatiles of cosmetics, acetone etc. Then visualize the information by changing LED color and on mobile phone through Bluetooth. iAir is a combination of fashion & design, physical computing, circuit design, and mobile & server development.
iAir is the project after half-semester research of indoor air pollution. With the idea of quantifying self and monitoring health, it is targeted to provide the easiest way to detect air quality surround you.
iAir has two necklace box-shapes to hold the inside circuit module: seashell and leaf. Made with 3D Printing and laser cutting respectively. Both of them recall the connection of air and nature. The shape of box has the function of balancing ventilation that go through the necklace, which ensures reliable data read form the sensor.
iAir is connecting with mobile phone through Bluetooth Low Enegry. Main circuit components includes TP-401 air quality sensor (grove air quality sensor), RFduino micro controller and a RGB Led. We designed our own libraries so as to “fake pair” with mobile app through BLE as well as calibrate & adjust sensor data.
