第一行显示DS3231实时(时、 分、秒 、温度)
第二行显示BME280(湿度、温度、偏移量)
第三行显示气压数值xxxxxxPa
第四行显示高度米
/***************************************************************************
This is a library for the BME280 humidity, temperature & pressure sensor
Designed specifically to work with the Adafruit BME280 Breakout
----> http://www.adafruit.com/products/2650
These sensors use I2C or SPI to communicate, 2 or 4 pins are required
to interface. The device's I2C address is either 0x76 or 0x77.
Adafruit invests time and resources providing this open source code,
