Abstract: Summer is coming, we will encounter such a situation. When lying in bed
reading or playing on the phone, the temperature is getting higher and higher, sweating
and tired, but do not want to get out of bed to turn on the fan, so is there a way , You
can turn on the fan without getting out of bed, the answer is yes, this is where the smart
fan is used, you do n’t have to get out of bed or manually turn on the fan, you only need
to connect Bluetooth with your mobile phone, you can remote It is practical and
convenient to control the switch and wind speed of the fan. The design of the smart fan
described in this article is based on the 51 single chip microcomputer. The control
terminal of the mobile phone uses the SPP Bluetooth serial port. The Bluetooth chip
uses the JDY-31 Bluetooth module. The assembled smart fan system is tested,
responsive, and operational Simple and practical. The paper introduces the usefulness
and potential value of smart fans in detail, which is well suited to the development of
the times and people's life needs. First, the development of MCU and Bluetooth in
recent years is described, which provides a good design for smart fans. Hardware
support makes it possible to realize the functions of smart fans. Secondly, this article
explains in detail how the intelligent fan system is designed in hardware and software,
gives descriptions and functions of each module of the system, and introduces how the
intelligent fan is used and realizes remote control in the design. The intelligent fan
system has the characteristics of reliable operation, low cost, simple operation and
strong practicability. It can be widely used in urban communities and has great
promotion value.
