This project aims to check the temperature inside your refrigerator without opening it. Knowing the temperature inside of your refrigerator allows you to determine whether your food is staying at a safe temperature and know when your favorite beverage is cold. Each time you open the door to the refrigerator, heat enters the
This project was made by two people; each had a Particle Argon. The data was published in the particle console and, by bidirectional communication, was sent to each other device. The Figure shows the measurement of temperature and "HOLA" sent to the other device to establish the communication.

Webhooks Integration
This tool allowed us to integrate all the data from the sensors used in the Adafruit Io website. The first step to making this integration was to include the Adrafuit IO library in the Particle Web IDE. Next, we had to configure the parameters that Adafruit IO needs to recognize our data measured from the sensors.
After the configuration was done, we built the Adafruit IO page and fed the graphs from the data collected. For the Adrafuit page, we needed to create a feed app and a URL that would be necessary to paste into the Webhook configuration to send the data acquired by the sensors.
Data
The data was collected and plotted live. Also, it is possible to set notifications and send those to our phones. When the temperature exceeds 15 degrees C, we will get a notification to solve the problem inside the refrigerator. The distance represents the measurements over time. This measurement is taken in inches, and the user must be farther than 6 inches from the sensor to get a valid notification to be sent to the temperature Argon.
