What is Callisto?

Transcript:

Callisto is a study on sunlight and how it affects temperature & light on different sides of a building. This study was conducted using a series of 4 weather-proof enclosures, each equipped with an ESP32, light sensor, and temperature sensor.

When powered, these enclosures were affixed to 4 sides of a building, each of which facing a specific cardinal direction, North, East, South, and West. Over the period of several days, in 15 minute intervals, these sensors would upload their current readings to the database.

On Callisto’s web application, these individual data logs would then be processed and sorted using MySQL to display in easily understandable graphs and averages.

The main goals of the study being to answer 3 questions. 

- What impact does building location and geographic factors have on the amount of natural sunlight it receives?

- Does the architectural design of the building cause an unequal distribution of sunlight across it?

- What is the relationship between natural light exposure and the temperature of the building?

Each sensor has a custom made PCB and enclosure. These sensors would measure the Lux and Temp throughout the day, as long as they had a working battery and strong enough WIFI connection. The enclosure was designed by me to fit the pcb that another member made.

We designed a web application to document the entire process. Using MySQL we were able to turn our raw data into graphs and averages that p

To properly present our web app, we constructed a kiosk for those reading through our project. Both the kiosk design and interior bracket were designed by me.

Overall, the whole study was very rewarding in the sense that I got to work on a massive project with teammates. We had fairly regular struggles with some of our sensors due to poor wifi on that side of the building, but other than that we made some pretty great work!
