This library for Arduino/ESP8266 connects an BMP280 per I2C, read the Temperature( degC) , Pressure (mBar) and Altitude (m).

BMP280 Arduino Library

This library uses I2C communication with Arduino/ESP8266 and read the Temperature( degC) , Pressure (mBar) and Altitude (m).

Pin Connection :

BMP280-----Arduino

VDD ----> 3.3V

GND ----> GND

SDA ----> PIN20 (arduino mega, changeable in begin)

SCL ----> PIN21 (arduino mega, changeable in begin)

SDO ----> GND (slave address 0x76)

CS ----> VDD (HIGH for I2C)

VDDIO ----> VDD

Instructions :

Copy the BMP280 folder to Arduino/libraries

Restart Arduino and Upload "measurments" sketch in Arduino.
