Kanari Pollutant Wearable Device

"Knowing is half the battle"

Wearable Pollutant Sensor Device to help individuals and families to be aware of the level of pollutants within their daily surrounding.  

The idea is the sensing of pollution and environmental feedback to provide transparency in the air we breathe. The initial intent was to target babies and young children who are more vulnerable to the exposure of air pollution. Due to their growing bodies, “children breathe a proportionately greater volume of air than adults. As a result, children inhale more pollutants per pound of body weight”. Since they are too young to know the dangers and effects of their environment, our device will help parents become more aware of their child’s surroundings. However, after sharing the idea with people it comes to the realization seniors or health conscious adults would find the device equally useful. 

The device will detect how much pollution (cigarette smoke or fumes from exhaust pipes) is emitted in the air. At medium pollution level the device will pulsate in an array of rainbow LED lights, at peak pollution level the device will sound a buzzer. 

The device would be best suited attached to the user or if intent for small child it is to be worn by the adult in supervision of the child.  The device will be light-weight, pliable, and the size of the FLORA, led and small re-chargeable battery with a dust optical sensor. 

Components

Input: 1 Dust particle sensor (recommend a back up)
Output: 1 Flora/wearable (recommend a back up), 4 Neo-pixel RGB lights, 1 Buzzer- PC Mount 12mm 2.048kHz, 1 mating connector specifically for dust sensor (buy 3 extras), crimp pins for 1.5mm pitch housing (buy 30 extras)

Strongly encourage to test the optical dust sensor with single LED and sound buzzer separately on arduino board to get the reading prior to map out our coding prior moving to the flora board. 

Testing out LED light and sound buzzer - PC Mount 12mm 2.048kHz with arduino- leonardo to ensure the print serial read from optical dust sensor is able to translate to the two output device.
 

Testing phase 2: Merging the optical dust sensor reading with the buzzer.

After testing the input and sensor on the arduino board it's time to test it on something smaller. We chose to test the optical dust sensor, neo pixel RGB light and buzzer onto the flora device with alligator clips. At this stage we switched from the Aduino Leonardo to Arduino Flora. One of the challenges that we ran into was we were unable to get a serial port read: usb tty on the first flora ordered. After debugging and hours of frustrations we realized we were shipped with faulty flora boards. So make sure you have back up components!
