Today’s smartphones utilize a wide array of accelerometers, gyroscopes and various other sensors in their designs. Relatively unknown is the barometric pressure sensor, which measures air pressure.

Most engineers understand the concept of pressure. It’s a force, often measured in pounds, on a specific area. It is commonly listed in pounds per square inch (psi). But there are a variety of ...

Some of the applications mentioned here require a room that maintains a higher or lower pressure compared to the surrounding ambient environment. If the isolated room has greater air pressure, it is ...

Nowadays, numerous electronic sensor modules are available on the market that can be combined with inexpensive microcontroller boards to measure environmental parameters of importance. The project ...

An HVAC pressure sensor is particularly important in the cooling cycle—which includes compression, condensation, expansion, and evaporation—where it helps regulate refrigerant flow. Proper airflow ...
