This project is part of the UNCC MEGR 3171 IOT Project. Our goal was to make a device that would take live updating temperature readings. To accomplish this we used 2 particle argons and a DHT22 temperature sensor. The first argon takes a temperature reading and sends the reading to the second argon. Once the second argon receives the temperature reading it determines if the temperature is below or above a certain temperature. If the temperature reading goes below the wanted temperature the argon will trigger the D7 light to turn on. If the second argon's light turns on, it tells the first argon to also turn its D7 light on. Subsequently if the temperature is above the specified temperature both argons will communicate and turn their D7 lights off.
The screenshot below shows the live data that was being uploaded to ThingSpeak. ThingSpeak takes the temperature data from the argon and then graphs it. This was the graph when the video was being made as it shows the temperature drops from around 70 degrees to then 32 degrees in the freezer. Once the argon was taken out of the freezer then the temperature reading jumps back up to around 70 degrees again.
The images below show the layout of the particle argons that were used in the project.
