2pcs GY-68-BMP280 BME280 3.3V 5V 디지털 기압 고도 센서 Arduino 용 고정밀 대기 모듈
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 from 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
