Elevator arrival reminder and automatic fault alarm

Few elevator maintenance managers need to manage and maintain a large number of elevators, making it difficult to detect elevator faults in time. Based on ST's SensorTile, the author implements the sensor's automatic detection of elevator arrivals and faults, which can serve as input for possible intelligent control systems, thereby enabling more efficient and convenient elevator use and management.

Abdominal breathing training trainer

The design is based on the SensorTile.Box kit, which is set to expert mode for direction change detection (using a gyroscope), close to the practitioner's lower abdomen; the LIS25BA bone conduction sensor collects and identifies the vibration signal of the user's breathing status at the nostrils. The signal output is also connected to the central main control circuit. The optimal compliance judgment for monitoring the breathing process coordination during the entire exercise process and the corresponding voice prompt information broadcast are made by the central main control circuit.

Engineer safety black box

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.

Shunt-Based High Current Measurement (200A) Reference Design Using Reinforced Isolation Amplifier

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.

Power Optimized 77GHz Liquid Level Transmitter Reference Design

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).
