BPI-M2+ Weather station:Air pressure sensor, temperature sensor,light intensity sensor arduino lib

BPI-M2+ Weather station_13_ The data uploading (arduino):

Used here hardware is more, also can upload only part of the sensor data

1.arduino nano (mega2560, uno all support)；
2.ds18b20;
3.dht11;
4.bmp180;
5.bh1750;
6.esp8266
(3~5 is option Modules)

Arduino through ESP8266 sensor uploading data to BPI, and ESP8266 need setting wifi user name and password ,let it auto login when boot OS .

pm2.5 and co2 you can add by youself ,please refer to the previous code
