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.
Alan Wang, a maker from Taiwan, used the MAX7219 LED module, the ESP8266-based D1 micro development board and MicroPython to develop a small tool that can update COVID-19 data in various countries in real time.

The Demand Controlled Ventilation People Counting Reference Design with 3D Time of Flight (ToF) is a subsystem solution that uses TI's 3D ToF image sensor and tracking and detection algorithms to count people in a given area, enabling high resolution and high precision. The sensor technology was developed in standard CMOS, enabling high levels of system integration at low system cost. Because ToF image sensors process visualization data in three dimensions, the sensor can detect the precise shape of the human body and track a person's movement and position (including minute changes in movement) with unprecedented accuracy. As a result, ToF cameras can perform real-time people counting and people tracking functions more efficiently than traditional surveillance cameras and video analytics.

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 SOCORAD32, also known as the ESP32 Software Controlled Radio, is a professional grade hackable radio for amateur radio exploration, voice and data communications using simple AT commands. Just add a speaker and batteries and you've got a fully functional walkie-talkie. With a dedicated Push-to-Talk (PTT) button onboard, SOCORAD32 works right out of the box without touching a line of code!
Power management for the energy harvesting, energy buffering and back-up power is a key challenge in the fault indicator design. The TIDA-01385 introduces a circuit about harvesting energy from a current transformer for the system load of a fault indicator while storing the extra energy in a super capacitor. A primary Li/SOCl2 battery is used as back-up power to extend the fault indicator operating time after the power grid fails. With input current from 3mA to 2A, the reference design provides a stable 3.6V to system load within two seconds.
Let’s see how to easily hack a remote control using ESP8266.
The Bidirectional 400V-12V DC/DC Converter Reference Design is a microcontroller-based implementation of an isolated bi-directional DC-DC converter. A phase shifted full-bridge (PSFB) with synchronous rectification controls power flow from a 400V bus/battery to the 12V battery in step-down mode, while a push-pull stage controls the reverse power flow from the low voltage battery to the high voltage bus/battery in boost mode. In this implementation closed loop control for both directions of power flow is implemented using Texas Instruments 32-bit microcontroller TMS320F28035, which is placed on the LV side. This digitally-controller system can implement advanced control strategies to optimally control the power stage under different conditions and also provide system level intelligence to make safe and seamless transitions between operation modes and PWM switching patterns.
NFC dynamic tag sensor node evaluation board
ST25-TAG-BAG-U contains five different projects (five of each type) based on NFC Forum Type 5 tag ICs (ST25TV512 and ST25TV02K) or NFC Forum Type 4 tag ICs (ST25TA02KB and ST25TA64K).
This fully tested reference design demonstrates a low-power solution for electronic measurement of water flow with a mechanical flow meter and provides a single-chip platform for water flow measurement and wireless communications. The design is ideal for automatic water meter reading (AMR) modules, which add wireless communications capabilities to existing mechanical flow meters. The radio frequency subsystem supports standard protocols such as wireless M-Bus or proprietary protocols in the sub-1GHz ISM band. This reference design provides the ability to accurately read mechanical rotation over long distances and provides greater reliability. Ultra-low power consumption reduces battery requirements and extends product life.

This reference design focuses on high-side current measurements using TI's range of voltage output current shunt monitors. This design can be used to measure high-side current in industrial applications where common-mode dynamics can drop below ground. Overall, this design helps designers build electromagnetic compatibility (EMC) compliant circuits based on current shunt monitor devices while achieving a highly accurate current monitoring solution in the presence of a wide range of -14V to +80V common-mode voltages.
