本项目是基于Cortex-M3 的地沟油快速检测装置，旨在实现“地沟油”快速，现场检测。MCU控制可编程的直接数字频率合成器（DDS）产生正弦激励信号，经过可变增益放大器（VGA）和低通滤波器（LPF）作用于食用油阻抗传感器（实验室制作）信号经过仪器放大器送入微控制器（MCU）的模数转化（ADC）通道，MCU对采集的信号通过快速傅里叶变换（DFT）处理，实现食用油阻抗与相角的检测；USB和以太网接口，可与计算机通讯，以便对采集的数据进行存储和分析。(The project is based on the Cortex-M3 waste oil rapid detection device designed to achieve " waste oil" rapid, on-site testing. MCU control programmable direct digital frequency synthesizer (DDS) generates sinusoidal excitation signal through a variable gain amplifier (VGA) and a low-pass filter (LPF) acting on the oil-impedance sensor (lab produced) to send signals through the instrumentation amplifier into the microcontroller (MCU) modulo conversion (ADC) channels, MCU signal acquisition via Fast Fourier Transform (DFT) processing, oil resistance and phase angle detection USB and Ethernet interfaces, and computer communication, in order to collect data for storage and analysis.)

智能温度控制器
当温控开关打开时，若测得环境温度大于设定温度，则继电器吸合
启动电机工作；若测得环境温度小于设定温度，则继电器释放，
电机停止工作；(When the temperature control switch is turned on, if the measured ambient temperature is higher than the set temperature, the relay will suck in.
Start the motor; if the measured ambient temperature is less than the set temperature, the relay will be released.
The motor stopped working.)
