注意GY-BME280-5V 地址是0x76，不是官网例程里面的0x77

###BME280 温度 + 压力 + 湿度传感器 地址0x76

我用BMP280  代碼是0x77

  - platform: aht10
  #  address: 0x38
    temperature:
      name: "AHT20 Temperature"
    humidity:
      name: "AHT20 Humidity"
    update_interval: 15s
    
  - platform: bmp280
    temperature:
      name: "BMP280 Temperature"
      oversampling: 16x
    pressure:
      name: "BMP280 Pressure"
    address: 0x77
    update_interval: 15s

模块的图片上，BMP280附近有个3个焊盘，那是个跳线，默认接到GND，i2c地址就是0x76，如果接VDD，就是0X77
