2 pieces GY-BMP280 Pressure Sensor Module Arduino High Precision Atmospheric
2 Pieces BMP280 Pressure and Temperature Sensor Package Includes2 x BMP280 Pressure Sensor Module Arduino High Precision Atmospheric2 x Straight 4×1 2.54mm Headers Bosch 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 Bosch is the 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 navigatione.g. time-to-first-fix improvement, dead-reckoning，slope detectionIndoor navigation（floor detection，elevator detection）Outdoor navigation，leisure and sports applicationsWeather forecastHealth care application（e.g. spirometry）Vertical velocity indication（e.g. risk/sink speed）Target devicesHandsets such as mobile phones ,table PCs, GPS devicesNavigation systemsPortable health care devicesHome weather stationsFlying toysWatchesPCB size:(L*W)1.52* 1.20cm/0.60″*0.47″
