"This portable device can be used anywhere to give an alert when a patient stops breathing"

Our final project for ECE 4760 is a respiratory monitor that was designed for low-resource environments. The device calculates a patient's breathing rate by detecting changes in temperature when the patient breathes through a mask. Features of the device include an alarm through a piezoelectric speaker which goes off when the patient stops breathing, and a low-battery indicator signal when the battery powering the device reaches a threshold voltage.
