| Intelligent electronic scale application system |
The newly purchased HX711 module is combined with the development board to make an intelligent electronic scale. The weighing UI interface is started (infrared sensing), the weight is recorded, and the input unit price is calculated. After the end, the infrared trigger is used again to display the weighing times and the cumulative total. The data is uploaded to the cloud, which is convenient for other host computers to obtain and analyze in real time. |

| Portable photo album recognition |
The idea came from a class reunion. Several years after graduation, I found that when I looked through the old photo albums, I couldn’t match the people. So I came up with an idea to use AI face recognition to define a function that can check where a person is in a photo. |

| Smart home control based on STM32F7508-DK |
Project reason: I have always wanted to make my own smart home terminal to respond to the current trend of intelligence, and to better accumulate my practical experience and contribute to my career. Functions: 1. STM32F7508-DK is the main control, collecting data such as temperature, humidity, and light intensity of the indoor environment, and displaying them on the screen of the development board. 2. Users can freely choose to turn on and off lights and other household appliances through the central control through the screen. (This item uses relays to control LED lights for simulation) 3. Send sensor data to the cloud platform through WIFI/Ethernet (developers choose one of the two), and parse the RPC control instructions of the cloud platform to achieve the effect of remote control of turning on and off lights (this item is the same as above, using relays to control LED simulation). Users can remotely monitor sensor data transmitted by smart home terminals/send remote control instructions through browsers/mobile phone APPs. |

| Small home weather station |
It mainly detects temperature, humidity, PM2.5, and light. In the future, it will consider adding wind speed and wind direction. It uses a 7-inch serial port screen for display. The main purpose is to obtain relevant information in time and add or remove clothes for the baby in time. It is okay in summer now. It is mainly used in winter, because it is easy for the baby to get sick in winter if you don’t pay attention. The wind speed and temperature felt in the room are completely inconsistent with those outdoors, so a small weather station is used to obtain information about the surrounding temperature, wind speed, etc. |

| Agricultural IoT Soil Analysis Sensor Collection Sensor |
This project uses a low-power precision analog microcontroller, temperature and humidity sensors, and environmental smoke sensors to collect current soil temperature, humidity, tension and other parameters, and converts the collected data into Modebus data, which is then sent to the background through DTU. At the same time, this system realizes automatic irrigation nodes through relay control. |

| Intelligent high-frequency signal wireless detection and control system |
For the detection of high-frequency signals, such as sounds that humans cannot hear and signals greater than 20kHZ, high-frequency signal detection equipment is needed to detect such high-frequency signals. After the high-frequency single-chip microcomputer performs FFT transformation and trigonometric function calculation, the measurement results are displayed. The built-in angle sensor realizes the calibration function for static measurement data and transmits it to the mobile phone APP terminal for display through the wireless wifi module. |

| Intelligent rehabilitation power bike monitoring system |
When rehabilitation personnel are exercising on the power bike, medical staff need to make targeted settings according to the plan and monitor the exercise process. In addition to checking the exercise status of rehabilitation personnel, it is generally necessary to check the heart rate and respiratory monitoring equipment worn by rehabilitation personnel. In actual scenarios, there are 5-15 rehabilitation equipment in a rehabilitation room, and medical staff are generally 2-3. Medical staff need to frequently check in front of each machine, so it is difficult to monitor the scene well when there are many people. This solution uses Bluetooth centralized management and will add a power bike monitoring system to the traditional power bike system. It can not only remotely set up the current power bike and upload the current rehabilitation personnel's exercise output, but also connect the current rehabilitation personnel's heart rate monitor and upload the data to the system. The receiving host can record the data in real time and project it on the large screen on site. On-site medical staff can monitor the site more carefully, and it also eliminates the need for secondary data collection (originally required to set or transfer from each machine). In addition, due to the epidemic, for some home rehabilitation personnel, medical staff can also remotely monitor and assist in exercise. This solution will help the rehabilitation power bike to achieve better monitoring and meet the medical care requirements of the entire community. |

| Smart Kitchen |
The smart kitchen has a screen that displays the kitchen environment status and can also teach you how to cook. The interaction is mainly non-contact through the TOF sensor. The purpose of the smart kitchen is to be more convenient, smarter, safer and more energy-efficient. STM32F7508-DK is used to connect to the Internet and display the steps of the dishes you want to cook, and to display some kitchen environment information. SI7021-A20-GMR is used to detect the temperature and humidity of the kitchen space, and ADPD188BI-ACEZR7 is used to detect the concentration of oil smoke that has not been sucked out of the kitchen by the range hood. After receiving the data, STM32 actively adjusts the power of the range hood, which can be healthier and more energy-efficient. VL53L5CXV0GC/1 is used for gesture operation, because in the kitchen environment, the screen is not easy to operate with wet hands, and the oil smoke is easy to attach to the screen, which cannot be used for a long time and is not easy to clean. The screen must be behind the glass, and the touch screen cannot be used. |

| Design of Industrial Temperature Transmitter |
The temperature of the constant temperature box and the hot and cold shock test box is collected and converted into 4-20mA current output to the PLC and other central control for processing. The central control automatically controls the equipment according to the set temperature and the collected current. (Due to time constraints, only the temperature collection and output 4-20mA part is done) |

| Based on STM32L496G-DISCO IoT harmful gas detection equipment |
In the suburbs and towns of northern cities, a large number of residents rely on coal for daily life and winter heating, and CO poisoning and death incidents occur every winter. On February 13, 2006, a CO poisoning incident occurred in Yanbian Prefecture, Jilin Province. The hospital confirmed 291 poisonings and 16 deaths. On the same day, 112 people were poisoned and 14 died in Mudanjiang City, Heilongjiang Province, and 87 people were poisoned and 4 died in Hefei City, Anhui Province. CO poisoning incidents have become serious catastrophic events with extremely wide impacts and endangering people's lives. Natural disasters have the characteristics of multiple control parameters and diverse action processes, and analysis and research must also consider their high-dimensionality and complexity. Based on STM32L496G-DISCO IoT harmful gas detection equipment, it can detect indoor CO, formaldehyde, and gas harmful gases, and display them in real time, alarm through the IoT module, and remote monitoring. |

| Multifunctional Perpetual Calendar Box |
The project is based on the LVGL perpetual calendar and obtains the current weather and other information through the network (buttons can be used to set the date, time or city). Because the development board supports offline voice and camera, the device can be woken up by specific keywords, and snapshots can be taken and uploaded to the server. |
