Multifunctional UV Sterilization Box

The function of this disinfection box - UVC ultraviolet sterilization. The sterilization will stop once the power contacts of the box cover are disengaged. The bright spot in the center is the UVC-LED of the sterilization box, and the interior is mirror-finished in order to achieve 360-degree reflection of ultraviolet rays to ensure that there is no dead angle to irradiate the sterilized items, so the frame is selected inside There will be another light point that is actually a reflection, but there is actually only one light source. UV is what we know as ultraviolet rays, and UVC is the C-band of ultraviolet rays. Among all the ultraviolet wavelength bands, UVC, short-wave ultraviolet rays, has the strongest sterilization effect, so it is widely used in sterilization technology. And UVC-LED has many advantages such as fast startup, more allowable switching times, available battery power, and fewer side effects. It has become a new, more efficient and environmentally friendly sterilization technology and has been applied to digital products. The UVC-LED lamp beads of the multi-function disinfection box have a lifespan of up to 10,000 hours under normal use of 5 minutes of sterilization each time, intelligent induction, avoid secondary infection, wait for 5 minutes, and the sterilization rate is 99.9%. Prevent infection, clean life, and protect the health of you and your family.

A solution for automotive gear shift switch based on Hangshun chip automotive grade MCU HK32A040C8T3

Throughout the global development of passenger cars, automatic transmission has been widely adopted. Its simple and easy to learn, convenient and intelligent characteristics bring drivers a more comfortable driving experience, and also better adapt to urban traffic. The implementation of the automatic shift function actually uses a gear shift switch instead of manual operation. The gear shift switch will control the shift fork and gear shift based on different engine speeds, vehicle speeds, and the driver's intention to press the accelerator. To achieve these automated operations, a shift switch requires a brain. The Hangshun chip M0 series automotive grade MCU HK32A040C8T3 is such a "brain", applied in gear shift switch schemes. Its main function is to receive signals from the gear shift switch and convert these signals into electrical signals that can control the car's engine, transmission, and other parts, thereby simplifying driving operations and providing great convenience for the driver. In the process of developing its new generation of electric vehicles, in order to ensure that the vehicle's performance, reliability, and safety reach the optimal level, after in-depth technical evaluation and multiple rounds of screening, Selis New Energy Vehicles finally chose a gear shift switch scheme based on the Hangshun chip HK32A040C8T3. The Selis engineering team has conducted a rigorous review of the functional characteristics, processing speed, power consumption performance, environmental adaptability, and cost-effectiveness of the Hangshun HK32A040C8T3 MCU in multiple dimensions. Hangshun's MCU has successfully conquered the engineering team with its outstanding performance, especially in high reliability and strong anti-interference ability. In addition, HK32A040C8T3 has high integration and flexible peripheral interfaces, providing engineers with greater design freedom and optimization space, making the entire electronic control system more compact and efficient. HK32A040 using ARM ® Cortex ®- M0 core, with a maximum operating frequency of 96MHz, built-in up to 124 Kbyte Flash and 10 Kbyte SRAM. By configuring the Flash controller registers, the remapping of interrupt vectors within the main Flash area can be achieved. And it supports traditional Flash Level 0/1/2 read-write protection and Flash code encryption (patented by Hangshun). Strong scalability 32-bit ARM CPU architecture, good ecological environment Rich peripheral resources to meet platform expansion Multiple packaging options available for LQFP64, LQFP48, QFN32, and QFN28 high reliability Car specification quality, compliant with AEC-Q100 Grade 1 Complies with ISO 9001 and IATFT 16949 quality management systems Supports -40 ℃~125 ℃ High cost performance ratio Equal performance/resources, with higher cost-effectiveness Quality service Complete ecological supporting facilities 15 years of design life, with a supply chain guarantee of over 15 years The gear shift switch scheme based on the Hangshun Vehicle Class MCU HK32A040C8T3 has been successfully applied in the Sailis new energy vehicle, which not only improves the electronic control efficiency of the entire vehicle, but also achieves lower energy consumption and better user experience.
