Our project is about monitoring the temperature in a room, to make sure that it is within the limit set by the user. The idea came about when we were thinking of ways to improve our everyday life. Some of us had roommates that would tamper with the thermostat to raise the temperature to uncomfortable levels, so the ability to detect and alert us when this happened was convenient. Fortunately, we had the tools at our disposal to do just this!
The device consists of 4 main parts, a 4-digit display, a temperature sensor, a buzzer, and a rotary dial. The ideal temperature is displayed as 2 digits on the 4-digit display with the initial temperature as 50. Using the rotary dial, the user can easily adjust this temperature threshold to be anywhere between 50 and 99 by simply turning the dial. One the ideal temperature has been selected, it is displayed on the 4-digit display, and the program constantly monitors the actual temperature to see if it exceeds this ideal temperature. If the actual temperature is ever greater than the ideal temperature, the buzzer plays an obnoxious melody to alert anyone in the vicinity. Until the ideal temperature is adjusted or until the actual temperature falls beneath this threshold, the auditory abomination continues.
