Room Temperature Monitor

The Room Temperature Monitor is a device designed to alert the user if the ambient room temperature is outside of a desirable range. The Monitor uses an Arduino Uno and TMP36 temperature sensor to sense temperature and trigger both a red light and buzzer as alarms for non-desirable temperatures. 

The device is powered by a 9V battery, which is held in a custom 3D-printed housing. The housing features a sliding cover that allows for easy replacement of the battery and a means of securing the battery inside the device.
