This project is about sensing a correlation between temperature, humidity, carbon monoxide, hydrogen, and UV levels in a greenhouse. The greenhouse gets the most sunlight out of any room in Lane Tech, so we wondered if there was any correlation with UV from the sun and the various gas levels in the room. We wanted to see how these gases worked together and created a mixture needed for plant life. This interested us because Lane's greenhouse does not get a lot of visitors, and houses plants, so it has different temperatures and gases than the rest of the school.
We constructed our "mote" by combining a photon computer, various sensors, and an enclosure to protect our computer from the water in the greenhouse while still being open to collect gas data. We found the code on Sparkfun's website. Sparkfun was the parts supplier and we put the code into Particle, which flashed the code to the photon. This code then collected data.
Our UV sensor did not work at all, so that part of the project was eliminated. Also, there was too much data that did not correlate, so we were not able to gain an accurate understanding of the correlation between the UV rays and everything else. However, we still gained understanding of the positive correlation between carbon monoxide and hydrogen gas, and the negative correlation between temperature and humidity in the greenhouse due to the spikes in our graphs. This was a fun and enlightening project that helped us with many valuable computer skills.
