What is nose airflow sensor | Respiratory sensor for breathing and respiration
This page describes Respiratory nose airflow sensor used for breathing and respiration with its features and specifications. It mentions nose airflow sensor working as breathing and respiration sensor.
Introduction: As per recent research deaths are increasing across the world due to COPD (Continual Obstructive Pulmonary Disorder). COPD is becoming third main killer in 2020. Most of the instances of COPD are due to tobacco smoking. Spirometry is the best choice to screen sufferers of getting COPD. Spirometry is becoming essential for patients suffering from respiration illnesses. Various biomedical sensors are available including breathing sensor to analyze biomedical symptoms of the patients. It is very easy to interface these sensors with Arduino, Raspberry Pi or microcontrollers.
What is Breathing and respiration sensor ?
Definition: Airflow sensor offers early warning of hypoxemia and apnea. The device which is used to measure respiration price in affected person is known as respiration sensor. This sensors assist men or women in need of respirations.
As shown in the figure, it consists of bendable thread that suits behind ears and two prongs fixed inside the nostrils. It uses thermocouple sensor which senses thermal respiration and airflow adjustments in addition to nasal temperature of inhaled/exhaled air. Normal human being has respiration rate of about 15-30 breaths per minute.
The nasal airflow sensor is available from Cooking hacks >>.
Nose airflow respiratory sensor working and interfacing
The respiratory sensor can be attached to arduino by means of analog input. It returns ADC value in the range from 0 to 1024. Above diagram depicts nose airflow sensor interfacing with e-Health sensor shield. It shows the connections between pins of both respiratory sensor and e-Health shield board. The e-health sensor has been developed by cooking hacks USA. It is compatible with arduino mega, arduino uno and respberry pi boards. E-health shield can be interfaced on top of the arduino or raspberry pi as it is pin to pin compatible to extend testing of various sensors along with these boards. This e-health shield is very useful for different biomedical sensor testing. It supports interfacing of about ten different sensors such as SpO2, body temperature, GSR, blood pressure, glucometer, breathing, position, ECG, EMG etc.
