实现基于单片的超声波测距。 单片机每隔1秒发送一串40KHz的方波，开中断待接收到回拨时，响应进行报警。(Ultrasonic Distance-based monolithic. SCM every 1 second to send a bunch of 40KHz square wave, open interrupt to be received back, the response of the police.)

温湿度传感器读取温湿度数值，有效解决了无法显示的问题(Temperature and humidity sensor reading temperature and humidity value, effectively solve the problem of unable to display)

基于stm32开发的频率检测及液晶显示，在显示时的测量范围为50hz到100khz。误差为<=1%。(Frequency detection and liquid crystal display based on stm32)

说明：  温度控制器，控制加热器的开启与关闭，两路温度采集，内部与外部，外部采用传感器(Temperature controller to control the heater turned on and off, two-way temperature collection, internal and external, external use of sensors)

RC522 IIC驱动程序，可实现读卡和写卡功能，复旦卡或M1卡都可以，本人也试过读公交卡，可以读出序列号和卡类型。(RC522 IIC driver, can read card and write card function, Fudan card or M1 card can, I also tried to read the bus card, you can read the serial number and card type.)
