The IOT device constructed for our project features the use of a TMP36 sensor that monitors temperature levels and a photodiode that monitors surrounding light. This IOT device solves the problem of not being able to monitor the temperature inside a refrigerator or freezer. The way this problem is solved is the IOT device is placed inside of whatever freezer or fridge needs to be monitored and real time data is recorded on a spreadsheet; the data is gathered by the Particle Argon device and sensors, sent to the spreadsheet with help from the IFTTT program, and recorded on Google Sheets. This is useful in the event of a power outage where someone might be unsure if food in a fridge/freezer has gone bad. This device can also be useful in an environment where the door to a fridge/freezer door is often left open on accident, if the door is accidentally left open for an extended period of time and there is concern if food might have gone bad the temperature can easily be checked to see if the food might have been too warm for too long. If the user of this device is away from home this device is useful because the temperature can be remotely checked to make performance is satisfactory. Someone might want this device if they have kids that accidentally leave the fridge/freezer open for extended periods of time. Another scenario where someone might want this device is if they have a restaurant and want to monitor the freezer to make sure the freezer operation is satisfactory, this could be extra useful due to the fact that there are not always people working at restaurants meaning the status of the freezer cannot always be monitored in person. What makes our device unique is that the photodiode can help detect if the door is open by sensing light shining in as well as the light that turns on when the door is open.Caleb's data
