【Raspberry pi+python+mysql】红外传感器-发邮件-存数据库

1、mysql

http://dev.mysql.com/doc/refman/5.5/en/tutorial.html

mysql+python

http://dev.mysql.com/doc/connector-python/en/connector-python-examples.html

先打开数据库连接：

conn=mdb.connect(host="localhost",user='root',passwd='******',db='sensor',charset='utf8')

再取得指针

cur=conn.cursor()

执行sql语句字符串

sql="insert into infrared_sensor(record_time,in_range) values(now(),'%s')"%param
cur.execute(sql)

提交事务，关闭指针，关闭连接

conn.commit()
cur.close()
conn.close()
