Gy-68 Bmp180 Bmp180 Bmp280 For Arduino

a Low cost pressure/temperature sensor that work with I2C protocol and very accurate and sensitive toward surrounding. 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 powered applications.

Specification

operating voltage: 1.6v~3.6v

dimension: 3.6mm x 3.8mm

operating current: 5uA

Description:

It has stepped up their game with their new BMP280 sensor, an environmental sensor with temperature, barometric pressure that is the next generation upgrade to the BMP085/BMP180/BMP183. This sensor is great for all sorts of weather sensing and can even be used in both I2C and SPI!

This precision sensor is best low-cost, precision sensing solution for measuring barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter accuracy

Typical application:

Enhancement of GPS navigation

e.g.time-to-first-fix improvement,dead-reckoning,slope detection

Indoor navigation(floor detection,elevator detection)

Outdoor navigation,leisure and sports applications

Weather forecast

Health care application(e.g. sirometry)

Vertical velocity indication(e.g. risk/sink speed)

Target devices

Handsets such as mobile phones ,table PCs,GPS devices

Navigation systems

Portable health caredevices

Home weather stations

Flying toys

Watches
