Air Pressure Sensor

Share This Post

Air pressure sensors are devices used to measure the pressure of air in a given space or container. These sensors can detect minute changes in air pressure and convert them into electrical signals that can be measured and analysed. Air pressure sensors are used in a wide range of industries, including automotive, aerospace, and HVAC, to name a few. This article will explore what an air pressure sensor is, the problems it solves, applications that use it, technical data, and the main manufacturers.

What is an Air Pressure Sensor?

An air pressure sensor is an electronic device that measures the pressure of air in a given space or container. There are various types of air pressure sensors, but the most common type is the piezoresistive air pressure sensor. This type of sensor works by using a diaphragm that deflects in response to changes in air pressure. The deflection is then measured by a Wheatstone bridge circuit, which converts it into an electrical signal that can be read by a microcontroller.
