基于STC89C52单片机的无线智能温控迷你电风扇

Wireless Intelligent Temperature Control Mini Fan Based on STC89C52 Single Chip Microcomputer

笔者基于STC89C52设计并制作了无线智能温控迷你电风扇。首先环境温度通过DS18B20进行检测,并将得到的温度转换为数字信号,发送给STC89C52,进而将温度显示在LED数码管上,此外,还将显示风扇的控制方式和风速的级别。直流电机风扇的转速将通过PWM脉宽调制方式进行调节。此风扇同时还具有无线遥控功能,无线模块采用NRF24L01芯片作为通信芯片,上位机采用51单片机作为主控芯片,实现风速控制、定时等功能。

The author designed and produced a wireless intelligent temperature-controlled mini fan based on STC89C52. First, the ambient temperature is detected by the DS18B20, and the resulting temperature is converted to a digital signal and sent to the STC89C52. The temperature is then displayed on the LED digital tube. In addition, the fan control mode and the level of the wind speed are displayed. The speed of the DC motor fan ,will be changed by PWM pulse width modulation. The fan also has a wireless remote control function. The wireless module uses the NRF24L01 chip as a communieation chip, the host computer uses 51 single-chip mieroeomputer as the main control chip, to achieve wind speed control, timing and other functions.
