手机万用表的设计

Design of Mobile Phone Multimeters

传统万用表体积大,不方便携带,采用指针读数存在人为误差。为此,将手机和万用表相结合设计了体积小的手机万用表。手机万用表的测量机构大小与钥匙扣相似,由单片机对被测量的信号进行处理,再由蓝牙模块送入手机,最后通过手机显示测量结果,并进行语音播报。

The traditional multimeter is bulky,inconvenient to carry,inaccurate because of pointer reading.In this paper,the mobile phone multimeter is designed,which is a combination of mobile phone and multimeter.The measuring mechanism of the multimeter is similar to a key chain in size.The measured signal is processed by the single chip microcomputer,and then sent to the mobile phone by the bluetooth module.Finally,the measurement result is displayed by the mobile phone and the voice broadcast is given.
