Story

This is a project that is part of the UNCC MEGR 3171 IOT Project. The goal of this project was to take live readings from two temperature sensors in connection to two Particle Argons. One sensor being a waterproof DS18B20 Digital Temperature Sensor, and the other being an Analog Temperature Sensor, Local -40°C ~ 125°C 10mV/°C. The waterproof sensors main goal was to take a live temperature reading of a fish tanks water. The lead end of the sensor was placed on the top surface of the fish tank water and recorded temperature values. The goal of the regular temperature sensor was to take simultaneous readings of the air temperature. Taking both readings, gave a conclusion on what the best room temperature is to keep the fish tank water at a suitable living temperature. With further research, it can be said that the most adequate temperature range for a fish is from 76 to 80 degrees Fahrenheit.

Once the code for each build was flashed, the D7 digitalWrite light appeared to insure that all was running smoothly and the temperatures were recoded.

As the readings were taken from each sensor, the data from the Particle Argon was sent to Google Sheets through IFTTT. The graph below displays this data through consistent temperature readings over about a 30 minute span for both room and water temperature

Google Sheets Room and Water Temperature data

The graph above depicts the overarching conclusion on differences between Room and Water Temperatures. Shown in blue is the water temperature data. It can be seen that on average, the water temperature is about 5 degrees cooler then the room temperature over a span of simultaneous time intervals. To conclude, the water temperature of this fish tank is at a suitable condition for average fish at about 68-70 degrees Fahrenheit.

Code

#include "OneWire.h"
#include "DS18.h"
DS18 sensor(D4);

char temp[0];
float temps=0;
int x=0;
int current_temp = 0;
int previous_temp = 0;

void setup() {
    pinMode(D7, OUTPUT);
  Particle.variable("fishy", temp);
}


void loop() {
  //tempSensor();
  x=analogRead(D4);
  current_temp=(((((x*3.3)/4095))*100)*1.8)+32;
  if (abs(current_temp - previous_temp) >=0)
  {
      digitalWrite(D7,HIGH);
      Particle.publish("fishy", String(current_temp),PRIVATE);
      digitalWrite(D7,LOW);
      
  }
  
  previous_temp=current_temp;
  delay(1000);
}
