WISDUM 5pcs High Precision BMP280-3.3 Atmospheric Pressure Sensor Replace BMP180/BMP186

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.

Watches Size: (L*W) 1.52 * 1.20 cm/ 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.
