树莓派中的配置

安装依赖

pip install smbus2

配置上传地址

# 如果服务器部署到了云主机，将 raspberry-pie-ht/pi-client/main.py 中下面代码片段中的 HOST 改成云主机的公网 ip

# 服务器配置
HOST = '127.0.0.1'
PORT = 3000
ADDRESS = 'http://%s:%s?identity=pi' % (HOST, PORT)
io = socketio.Client()
io.connect(ADDRESS)
print('connect to %s' % ADDRESS)

启动获取并上传温湿度的 python 程序

# 将工作路径切换到项目根目录
python ./pi-client/main.py

服务器配置
