Abstract

The respiratory rate is one of the most crucial measures of a person's health. It is the rate at which a person breathes while at rest, measured in breaths per minute. The rate of respiration changes from child to adult, as well as when a person is unwell. The suggested respiratory rate control is built using an electrical circuit and a push switch. An elevated respiratory rate can signal a number of pathological problems, including respiratory, cardiovascular, and metabolic issues. We've created a breathing sensor that's non-invasive, compact, simple to use, and affordable. This gadget measures the temperature differential between the inhalation and exhalation stages of the respiratory cycle. Individually, digital stethoscopes on the market are often not inexpensive, particularly in poor nations and impoverished areas; they are a fantastic tool for doctors, but with telemedicine, we need the instrument to diagnose patients remotely. The idea is to develop a device that combines a traditional stethoscope with a broadband microphone and uses a Sound sensor MAX4466 detect airway sounds. The gadget and LCD detect and display whether it is normal breathing, which is shown by a green light led blinking, or abnormal respiration, which is shown by a red light led blinking.
