BMP180 Dijital Hava Basıncı Sensörü
Bosch BMP180 sensörü kullanılarak yapılmış basınç sensörüdür. Havadaki basıncı ölçerek dijital şekilde çıkış veren sensör modülüdür. Hava basıncına göre sensör yüksekliğinin anlaşılmasından dolayı, çeşitli multicopter projeleri başta olmak üzere pek çok uygulamada kullanılabilir. I2C haberleşmesi formatında iletişim kurulmaktadır.
BMP180, 300 - 1100 hPa arasındaki basınç değerini ölçebilmekte ve 500 metre ile 9000 metre arasındaki yükseklik ile ilgili bilgi vermektedir. 0.03 hPa (0,25metre) gibi çok yüksek bir çözünürlüğe sahiptir.
The BMP180 is the new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smartphones, tablet PCs and sports devices. It follows the BMP085 and brings many improvements, like the smaller size and the expansion of digital interfaces.
The ultra-low power consumption down to 3 μA makes the BMP180 the leader in power saving for your mobile devices. BMP180 is also distinguished by its very stable behavior (performance) with regard to the independency of the supply voltage. Measuring the absolute pressure of the enviroment using a digital barometer such as this has some interesting applications. By converting the pressure measured into altitude, you have a reliable sensor for determining the height of your robot, plane .
Using a sensor as capable as the BMP180 you can achieve accurary of 1m, with noise of only 17cm in ultra high resolution noise.
Using I2C, the device provides pressure and temperature as 16bit values, which are used along with calibration data within the device are used to provide a temperature compensated altitude calculation.
