As China's title of "Infrastructure Maniac" becomes widely known, more and more workers are engaged in dangerous jobs, such as high altitude, underground, tunnels, and engineering vehicles. In order to ensure the safety of these construction workers and ensure timely rescue in the event of an accident, I designed this safety black box for engineering personnel. This equipment can collect the heart rate of construction workers, the temperature and humidity of the surrounding environment, identify the state of movement, and determine whether a fall or collision accident has occurred. It is transmitted to the remote monitoring center through the network. Once the monitoring personnel find an abnormality, they can immediately organize rescue.
This project uses the LSM6DSOX+STEVAL-MKI109V3 mode for preliminary sensor learning and research, mainly from training the acceleration sensor to detect vibration and recording vibration waveforms, training the gyroscope sensor to detect the vibration direction and offset, and recording the waveform for analysis; combined with the acceleration sensor and the action data of the gyroscope sensor can determine the vibration intensity and direction of the wind turbine tower under various working conditions; in practical applications, the LSM6DSOX sensor is combined with the low-power chip STM32L010RBT6 chip, and the main control board on the local side leads to an alarm relay. The outlet is used for alarm output on the wind turbine tower side. It is connected to the wind turbine scada system through 485 serial port communication to upload the recorded data on the local side to provide real-time feedback on the working status of the wind turbine tower. It can be used to analyze the vibration reverse and wind turbine tower vibration. Swing direction recording can also record and analyze the natural frequency of the wind turbine tower under normal conditions and the natural frequency during faults. The multi-faceted data forms a wind turbine tower disaster warning system that can be sensed in advance;
This project uses LSM6DSOX high-performance sensor and LIS25BA high-precision bone conduction sensor to control the four-axis robotic arm. By combining FMS and MLC with LSM6DSOX, the robotic arm can grab and put down items. Through LIS25BA, the vibration can be recognized and the steering gear can be controlled to complete the corresponding actions.
My initial idea for the "Badminton Training Device" project was to sense the form and intensity of the racket swing, whether it hit the badminton and where it was hit, etc., record the quality of all swings after a game, and combine it with the host computer to make a badminton shot. Play the practice analysis system. The MLC and FSM modules in LSM6DSOX can analyze and identify actions, which greatly reduces the data processing requirements of the MCU and can save resources to complete prompt or record functions.

The TIDA-00912 TI reference design provides a complete isolated current measurement reference solution using an external shunt, reinforced isolation amplifier, and isolated power supply. Parallel voltage is limited to 25mV. This reduces power dissipation in parallel connection, enabling high current measurement ranges up to 200A. The shunt voltage is amplified by an instrumentation amplifier configuration with a gain of 10 to match the isolation amplifier input range for better signal-to-noise ratio. The output of the isolation amplifier is level shifted and adjusted to match the full input range of the 3.3V ADC. This design uses a free-running transformer driver operating at 410kHz to generate an isolated supply voltage in a small form factor to power the high-voltage side of the circuit.

This reference design is suitable for automotive high-intensity lighting systems such as headlights and taillights, as well as interior LED lighting systems. It is designed to operate over an input voltage range of 6V to 18V and is capable of driving multiple strings of 6 to 7 LEDs in series (16V to 24V) at a constant current of 1A. This reference design supports analog LED brightness control and output open circuit protection. In a boost-to-battery configuration, the input voltage can be above, below, or equal to the desired LED string voltage.
TI Design TIDEP-0091 highlights strategies for power optimization of IWR14xx 76- to 81-GHz mmWave sensors in tank level-probing applications, displacement sensors, 4- to 20-mA sensors, and other low-power applications for detecting range with high accuracy in a minimal power envelope. In these applications, the system often operates on a low-voltage data line that provides less power than the operational power consumption. Duty cycling is critical to reducing the average power to meet the power input restrictions. Power optimization is achieved through MSP432 external duty cycling the IWR14xx device for periodic sensing. Additionally, this TI Design provides a sample configuration for single-dimensional range detection.Read more about fluid-level sensing using 77-GHz millimeter wave (SPYY004).Watch the introduction to level sensing (video).
