Story

Ideation

Our group is trying to figure out how factors such as temperature, humidity, time of day, and lighting causes students to sleep in classrooms.

Many students tend to fall asleep in class, and sometimes it is not due to how "boring" a class is. It can often be caused by the environment they are in or a certain time of the day that causes them to fall asleep. We wanted to narrow down the specifics to this occurrence.

Build

We created the box to enclose the photon with two holes at the top. We put one hole so that the temperature/humidity sensor could stick out and the other one was so that we were able to press the button.

How It's Used

Once plugged in it would collected the temperature and humidity of the room. If we saw a student(s) sleeping we would press the button on our "mote" that would count how many students were asleep. The amount of times we pressed the button was based on how many students were asleep. Since we had previously done a project with the a temperature/humidity sensor, we kept that on our breadboard and added a button to be able to count the amount of students sleeping. Also, the photon was programmed to restart the count at 0 at the beginning of every class period.

Challenges

We had problems with coding and trying to get all the code to work both properly and in unison, but this was one of the minor problems. There were also small problems with the wiring that lost us some time. The one major problem we had was with creating the wooden box. We had used the wrong file and we ended up cutting the boxes 2 days after our intended date. Another challenge was the limitation of our placement for our mote. Limited by the length of the cord, in some classes we were forced to get up to press the button on our mote.

Results

We learned that the majority of the classrooms are roughly around the same temperature, but the most important factor in students falling asleep is the lesson plan and its ability to retain student interest and most importantly involvement.

    double checkHum = dht.getHumidity();
    double checkTemp = dht.getTempFarenheit();
    
    if (checkHum > 0 && checkHum < 100)
        hum = checkHum;
        
    if (checkTemp > 32 && checkTemp < 100)
        temp = checkTemp;
    
    Serial.println("Temp: " + String(checkTemp));
    Serial.println("Hum: " + String(checkHum));
        
    delay(3000);
}
