The purpose of this project was to use two-particle argon to read the temperature of a room in order to try and save money on heating and air conditioning. This was achieved by having one argon setup with a temperature sensor to read and collect data on the current temperature and by having the second argon setup with an LCD display so the current temperature could be seen easily. This allowed us to get the reading from the temperature sensor without having to be in the same room as it. The first step of the project was to build the circuit for each of the particle argon. One team member was responsible for building the LCD circuit and the other was responsible for the temperature sensor circuit. Once each circuit was built, both argon were moved to the same particle account. Having both particle argon on the same account is the only way to achieve two-way communication between the two of them. The particle argon controlling the LCD display was able to subscribe to the particle argon collecting data from the temperature sensor. This allowed for the current temperature to be outputted on the LCD display. The code to accomplish this was taken from several similar IoT projects on hackster and was modified to achieve our goal.
In addition to having the temperature displayed on the LCD, our project also utilized IFTTT (If This Then That) in order to receive phone notifications whenever the temperature goes above 73 degrees. This is very helpful in alerting us when to turn the heat or AC on or off. The changes in temperature over a period of time were collected using the particle and plotted on a graph as well. The plot can be seen below
