Description: 全自动可遥控旗帜升降系统以AVR单片机为核心，由PWM对电机进行变频调速，高精度光电编码器测速，闭环式电路控制。能够利用按键输入相应的指令控制旗帜的升降，还可以实现在特定位置停留的功能。利用LCD可以显示旗帜的实时高度和相应的控制命令，用LED指示旗帜是否处于半旗状态，具有语音提示报警功能，并可利用无线模块实现遥控功能，准确均匀地实现旗帜的升降-Automatic landing system can be remote-controlled flag to AVR microcontroller core of the PWM VVVF motor, high-precision optical encoder gun, closed-loop control circuit. Enter the appropriate button to take advantage of the command control of the rise and fall of the flag, but also can stay in the function of a specific location. LCD can display the banner of the use of real-time high and the corresponding control command, the LED is directed at the flag half-mast, and alarm functions with voice prompts, and the use of wireless remote control function module, to achieve uniform and accurate take-off and landing flag

Description: We use Atmel AVR ATmega8535 microcontroller and LM35 temperature sensor as the main components of the system. Liquid Crystal Display (LCD) and buzzer are used to display the server room temperature and as an alarm, respectively. In order to alert the server administrator, the system is equipped with a GSM modem to immediately send text message if the server room temperature is above a predefined threshold. A relay board is also connected to the microcontroller to control other electronic appliances inside the server room.
