ITEM NAME:gy68 bmp180 replace bmp085 digital barometric pressure sensor board arduino JR Description: 100% Brand new and high quality This device is really easy to use, if your thinking of using it with an Arduino then you need to check out our BMP180 arduino tutorial 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 or projectile! Using a sensor as capable as the BMP180 you can achieve accurary of 1m, with noise of only 17cm in ultra high resolution noise. The device will operate at only 0.3uA meaning low current draw for battery.This device is really easy to use, if your thinking of using it with an Arduino then you need to check out our BMP180 arduino tutorial.
