BMP280 BMP280-3.3 High Precision Digital Atmospheric Barometric Pressure Atmospheric Pressure Sensor Replace BMP180/BMP186 3.3V

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

Size:(L*W)1.52* 1.20cm/0.60"*0.47"

Package Included:

1* 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.
