Inspiration
We were inspired by climate change decreasing the quality of the air. We are passionate about improving the planet and spreading awareness about climate change and how it affects air pollution.
What it does
It uses a DHT11 sensor to detect temperature and humidity of the air and essentially determines air quality, and lets us know of the air quality by using the rgb pin to show us red (bad air), yellow (ok air), and green (good air)
How we built it
We used a breadboard and attached the sensor and and a few wires alongside a resistor to it. For the RGB pin, we used 3 resistors and a few others wires to connect it to the other 3.3 voltage and make it light up.
Challenges we ran into
We accidentally fried the first DTH11 sensor because we didn't know that we had to connect it with the Arduino indirectly. We also could not get the sensor to work.
Accomplishments that we're proud of
Understanding the Arduino software and hardware in general, even if we didn't complete the project in whole
What we learned
We learned Arduino, hardware, from our mistakes (like not shortcircuiting sensors), alongside applying circuits, including parallel and series resistors.
What's next for Air Quality Sensor
Actually getting it to work and successfully detect the air quality
