FossaSat-1 uses cheap LoRa modules to provide free and open source IoT communications around the world, allowing students to communicate with satellites for less than 20 euros.
RSL10 QFN EVB is used as the main control of IOT lamps. Because the GPIO of RSL10 is limited, the data protocol adopts single-line return-to-zero code communication method. The system only needs one GPIO1 as the LED RGBW driver. GPIO is used to drive WS2812. WS2812 is a control circuit and An intelligent externally controlled LED light source with integrated light-emitting circuit. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel. The pixel contains an intelligent digital interface data latch signal shaping amplification drive circuit, a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent. , the other ADC port is used to collect the temperature of the lamp, and when the temperature exceeds the limit standard, it automatically reduces the luminous efficiency of the lamp to avoid burning out the LED due to excessive temperature.
A smart wearable device based on the RSL10 development board officially provided by EEWORLD. This device is divided into two parts: the host and the slave. However, this MCU only has one UART, but in actual project requirements we need to use two UARTs. The organizer of this event gave five boards, so a board without a sensor is used as the SPI slave and will receive The command parses and uses AT commands to control the audio.
The RSL10 module is plugged into the self-made optocoupler isolation circuit board, and the entire module is connected in series with the modified target instrument (4-20mA two-wire passive digital display meter) and then connected to the 4- In the 20mA current loop, when the actual working zero current is 4mA, the target instrument displays 4.000mA in the current mode; the overall voltage drop of the circuit board of the work is 2.513V; the changed range or unit is sent to the RSL10 on the circuit of the work through the mobile APP Setting command, the target instrument (currently its own voltage drops by more than 1V) will be changed by Bluetooth remote control to change the setting state, such as switching to different ranges or displaying different measured physical quantity units, etc.
It consists of two parts: the outdoor end (Outdoor) and the indoor end (Indoor). The Outdoor end can be placed outside the window to monitor real-time outdoor temperature, humidity, air pressure, illumination and other information. The Indoor is placed indoors to receive weather data and display it.
The project implementation uses RSL10 and external mechanical control structure to complete wireless control of traditional switches.
The work is mainly based on smart watches as a product that contributes to mine operations. The shape of [RSL10-SENSE-GEVK] is perfect for making a watch. All the onboard peripherals are utilized. The watch will collect data every once in a while and store it in the onboard external Flash. A total of fourteen days of historical data can be stored. If the power consumption is reasonably designed, it can Replace the button battery every two months. Normally worn in the normal mode, you can enter the downhole mode by pressing the button. In the downhole mode, the surrounding environment will be detected. When the environment reaches a bad situation, it will enter the alarm state. At the same time, when the person going down the pit feels uncomfortable, he can long press the button to enter the call for help state.
The project uses RSL10 to build a sugar glider health monitoring system. With good exercise and diet, my little jelly (sugar glider) can grow up healthily.
The acceleration sensing unit (RSL10+KX023) attached to the back of the door is used to detect vibration and movement to detect events such as opening the door and knocking on the door. It also interacts with the terminal through information through BLE and can view the log on the handheld terminal. Handheld terminals are also implemented with RSL10. After powering on, it automatically scans the target device and connects to it. After connecting, it obtains the time and date information of the device (which can be modified at this time), and then enters the log interface. The wireless sensing unit and the BLE terminal exchange information through the BLE connection.
In view of the characteristics of students' dormitory life, an IoT smart dormitory system is built using ON Semiconductor's RSL10 low-power Bluetooth chip to implement several functional nodes, and a very convenient WeChat applet is used on the control end to monitor data. Through the functional units composed of RSL10 boards for data collection or action control, and realizing the monitoring function of WeChat applet, this project is a simple intelligent control solution for student dormitories, which can be used as courses/graduation projects for students in related majors. Or a case study of ON Semiconductor University planned courseware.
The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!
This design is designed for foot posture. Wrong running posture can be corrected through real-time prompts on the mobile phone APP, thereby solving various adverse consequences caused by incorrect running posture.
The author is located in an area with a lot of convective weather and hot and humid weather. I stared at it silently, and saw that the clothes to be dried came in and out five or six times a day... Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...
The ST25-TAG-BAG-UB is a ready-to-use tag set, containing tags based on NFC Forum Type 5 tag ICs (ST25TV02K and ST25TV02KC) or on NFC Forum Type 4 tag ICs (ST25TA02KB and ST25TA64K).
