About HiLetgo 5pcs High Precision BMP280-3.3 Atmospheric
Description: 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. 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 toysv Watches Size:(L*W)1.52* 1.20cm/0.60"*0.47" Package Included: 5 * GY-BMP280-3.3 Atmospheric Pressure Sensor Tip:The I2C address was 0x76 and not the 0x77 default used by most other sensors. You have to manually change the address inside the Adafruit_BMP280.h to: #define BMP280_ADDRESS (0x76),Then it started to work.
