+Using BME/BMP280 sensor from Bosch at AVR mikrocontrollers like Atmega328p
 
-This Library allowed you to use BME280 to sense temperature, pressure and humidity with AVR microcontroller like Atmega328.
-For communication with the BME280 I'll use my own I2C library (settings for I2C in i2c.h).
+This Library allowed you to use up to two BME/BMP280 to sense temperature, pressure and humidity (only with BME280) with AVR microcontroller like Atmega328.
