Barometric sensor
Barometric Sensor
A Barometric Sensor (pronunciation: /bærəˈmɛtrɪk ˈsɛnsər/) is a type of sensor that measures atmospheric pressure.
Etymology
The term "Barometric Sensor" is derived from the word "Barometer", which comes from the Greek words "baros" meaning weight, and "metron" meaning measure. The suffix "-ic" is added to denote relation or pertaining to, and "sensor" is a device that detects or measures a physical property.
Function
A Barometric Sensor measures the weight of the column of air above it, which is a measure of the atmospheric pressure. This measurement is used in various applications, including weather forecasting, altitude estimation, and in some medical devices.
Related Terms
- Atmospheric Pressure: The pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals (roughly 14.6959 pounds per square inch).
- Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
- Barometer: An instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
- Altitude: The height of an object or point in relation to sea level or ground level.
Applications in Medicine
In the medical field, Barometric Sensors are used in devices like CPAP machines for sleep apnea treatment. The sensor helps to adjust the pressure of the air delivered to the patient based on the atmospheric pressure, ensuring the patient receives the correct amount of air pressure.
