Respiratory monitoring system for asthma patients based on IoT

Nowadays peoples are suffered from breathing problems. The diseases which include various ailments in the form of sleep apnea, chronic obstructive pulmonary disease and asthma. These diseases are the main cause of hospitalization for elder people. People who have suffered from chronic diseases are needed to repeatedly monitor the vital signs periodically. The vital signs are the basic measurements of body functions. The vital signs of our body are heart rate, temperature, blood pressure, respiratory rate, oxygen saturation and blood glucose level. The respiratory rate monitor is one of the important vital signs which is useful for patient's who admitted in Intensive Care Unit (ICU). The respiratory rate is calculated by using LM35 temperature sensor and monitored the patient's respiration continuously based on voltage value of inhaled and exhaled air. NRF24l01 is used to transmit the sensor data from home to medical center. Then the data are published in a webserver using Ethernet to know the patient's status which is useful for doctor. And also the data is displayed in a Liquid Crystal Display (LCD). Once the threshold is reached, the alarm is generated and also a message generated in a webpage. Thereby doctor or medical professionals know the patient's conditions without delay. By using data mining techniques, people may know their condition without medical professionals help.
