Pressure sensors, transducers, and more specifically, the BMP180, have started to become more popular in a variety of applications. The reason for this is simple: the BMP180 is a reliable and cost effective pressure sensor with lots of features to offer. This article will look at the application fields of the BMP180, as well as its working principle.

Application Field

The BMP180 is a very versatile pressure sensor. It is primarily used for measuring barometric pressure and altitude, but it can also be used for temperature measurements. The primary application fields for the BMP180 include:

• Aviation
• Industrial Process Monitoring
• Meteorology
• Aeronautical Design
• Medical/Surgical Equipment
• Marine/Oceanographic Applications

The BMP180 can also be used in computer systems and mobile devices, where accurate pressure readings are often needed. It can also be used for faster and more accurate altitude and direction determination in GPS systems, and for controlling altimeter displays in aircraft.

Working Principle

The BMP180 is based on a principle known as the “piezoresistive effect.” This effect involves a change in electrical resistance due to a change in the mechanical stress on a material. In the case of the BMP180, a silicon diaphragm is used as a pressure sensitive element. The pressure on the diaphragm causes it to bend, and this causes a change in electrical resistance. The change in resistance can then be used to measure the pressure.

The BMP180 uses a combination of two pressure sensors—a MEMS pressure sensor and a temperature sensor—to provide accurate and reliable readings. The MEMS pressure sensor measures the pressure, while the temperature sensor measures the temperature. The readings from the two sensors are then combined to provide an accurate measurement of the barometric pressure. The BMP180 also has built-in temperature and pressure compensation that helps to ensure accuracy in a wide range of temperatures.

The BMP180 is a very versatile and reliable pressure sensor. It is easy to use and relatively inexpensive, making it a popular choice for a wide range of applications. The combination of features offered by the BMP180 make it an ideal choice for applications that require accurate and reliable measurements of barometric pressure.
