The Bluetooth base station designed this time for smart running shoes is mainly used in school classrooms, gyms and other places. Taking school classrooms as an example, schools and parents pay attention to students' daily exercise and learning status, and balance work and rest. Students put on smart shoes and place Bluetooth base stations in the classroom. Without getting rid of mobile phones, each student's movement status can still be collected that day. When students attend class, the base station automatically connects to the smart shoes via Bluetooth and obtains the step count, and stores the student ID and step count. After the day's class, the teacher can use the PC software to check the status of the students that day. During the class, the teacher can also use the PC software to control the connection to the designated smart shoe device.
"Portable information board", as the name suggests, displays the information you want to display on a device (screen) that you carry with you. The inspiration for this idea was that I met many elderly people who were lost before, but some of them were too old, had poor memory, forgot where their home was, couldn’t find their family members’ phone numbers, etc. (Although there are only a few, they are still exists, and China’s population is aging increasingly, so the proportion will inevitably increase).
This work is a simple pedometer design. It mainly uses MEMS sensors to detect changes in human body posture. It uses a pedometer algorithm to implement a simple pedometer function. It uses an OLED screen as a display device and adds a GY-30 light sensor module to detect changes in brightness of the surrounding environment. To adjust the OLED backlight brightness in real time; at the same time, the on-chip RTC is used to realize the real-time clock function. Due to limited time resources, it can be expanded later to add heart rate detection, temperature, humidity and air pressure, voice playback and networking functions.
Using the wearable sensor function of SensorTile.box, you can intuitively observe your movements and training conditions through curves when doing push-ups and planks.
This work monitors the child's sitting posture when writing. When the child sits upright, no prompt is generated. When the child lowers his head, the sensor light flashes to signal an alarm!
The TIDA-01520 two-stage reference design drives two LED strings in automotive headlight applications and automatically adjusts the pre-boost voltage without the need for a microcontroller (MCU), saving space and cost. In addition, the design's adaptive pre-boost control feature reduces switching losses and maximizes system efficiency for automotive headlights.
The new SimpleLink™ multi-standard SensorTag kit helps you realize your Internet of Things (IoT) product ideas. The kit contains 10 low-power MEMS sensors in tiny packages that are expandable using DevPacks, making it easy to add your sensors or actuators. Connect to the cloud via Bluetooth® and get sensor data online in three minutes. SensorTag works right out of the box with iOS and Android apps, so no programming experience is required to get started. The new SensorTag is based on the CC2650 wireless microcontroller (MCU) and consumes 75% less power than previous Bluetooth products. Therefore, the SensorTag kit can be battery powered and a coin cell battery will last for many years. Bluetooth SensorTag contains iBeacon technology. As a result, your phone can launch apps and customize content based on SensorTag data and physical location. Additionally, SensorTag kits are enabled via ZigBee® and 6LoWPAN technologies.

This low-power mode scheme achieves processor power consumption of less than 0.1 mW while maintaining LPDDR2 memory power consumption in the self-refresh state at approximately 1.6 mW. The system solution consists of AM437x Sitara processor, LPDDR2 memory and TPS65218 power management IC, and has been optimized for new low-power modes while supporting traditional low-power modes. Minimize processor power by turning off all processor power except the RTC power. System power state transitions, including power control, can be performed by a single interface signal (PMIC_PWR_EN signal) using PMIC register programming.
