So happy that my project is complete and I am able to play a small role in my school and city greener using space data, home made air quality sensor, and collaboration of other school students.

I mapped all the data I generated on a map so that other children can view it and find out how green are their schools. They can also send and share pictures of new trees they are planting in their schools to make them greener.

Here is the code I used to programme my Home Built Pollution Sensor using Arduino and Grove Dust Sensor.

int pin = 8;unsigned long duration;unsigned long starttime;unsigned long sampletime_ms = 30000;//sampe 30s ;unsigned long lowpulseoccupancy = 0;float ratio = 0;float concentration = 0;void setup() { Serial.begin(9600); pinMode(pin,INPUT); starttime = millis();//get the current time;}void loop() { duration = pulseIn(pin, LOW); lowpulseoccupancy = lowpulseoccupancy+duration; if ((millis()-starttime) > sampletime_ms)//if the sampel time == 30s { ratio = lowpulseoccupancy/(sampletime_ms*10.0); // Integer percentage 0=>100 concentration = 1.1*pow(ratio,3)-3.8*pow(ratio,2)+520*ratio+0.62; // using spec sheet curve Serial.print(lowpulseoccupancy); Serial.print(","); Serial.print(ratio); Serial.print(","); Serial.println(concentration); lowpulseoccupancy = 0; starttime = millis(); }}

Yes. My home made pollution sensor worked and I was able to get good readings. Areas with more trees had better air quality than areas where there are less trees. So higher school tree densities matter in keeping our air cleaner and children healthier

I was excited. As I am learning Arduino I wanted to apply my coding and making skills to this project too. So I built a home made pollution sensor using Arduino, and programmed it to collect air quality data! I then took that sensor to different schools and busy street intersections to see if trees make a differnce in air quality.

I then ranked the french-board schools according to their tree densities and created a Top 5 list!

So I used satellite data and a cool free tool provided by USDA Forest Service to map tree area of 15 schools in Toronto. I then calculated their tree densities and the amount of carbon they absorb.

As I love space and have previously worked on Canadian Satellite RadarSat-2, I thought it would be wonderful to see if I could use space data to capture school trees. I found I could using data from different satellites including NASA LandSat 8 and Sentinel 2.

It was fun to look at my school and those of my friends from Space. Some schools were definitely more greener that others as they had trees on their boundary or near school buildings. Some schools did not have many trees!

I realised that most city maps do not cover school parks because they are small and their tree densities is less. But we spend so much time in school and playing in school parks. School parks are important but data about them is missing.

Inspired from School Strike for Climate I wanted students to also take some action.
