High-tech human-machine interface integration is rare in China. Recently, Silicon Laboratories, a leader in high-performance analog and mixed-signal ICs, announced the launch of a new generation of infrared light for human-machine interface (HI) applications. IR) and Ambient Light Sensors. The latest member of the SiliconLabs QuickSenseHI portfolio, the Si114x family, is the industry's most sensitive, energy-efficient and farthest proximity sensor. Available in a tiny 2mm x 2mm package

The Si114x sensor can be used in mobile phones, e-readers, netbooks, tablet computers, personal media players, toys, office equipment, industrial controls, security systems, point-of-sale terminals, and many other devices to enable advanced proximity and non-contact interfaces.

The detection distance and sensitivity of the proximity sensor are determined by the signal-to-noise ratio (SNR) of the system; the higher the SNR, the greater the distance. A variety of variables affect the system's SNR, including ambient noise/light compensation, photodiode sensitivity, filtering, and analog-to-digital converter (ADC) architectures. Although competing solutions may overcome one or both of these factors, the Si114x architecture in the patent application overcomes all these variables, thereby minimizing noise and maximizing performance. The joint architecture optimization of the Si114x series achieves a very high system SNR, which enables the Si114x proximity sensor to achieve the industry's farthest sensing distance, highest sensitivity, and fastest data acquisition speed.

The Si114x family's industry-leading sensitivity allows developers to place infrared sensors behind a translucent product cover. The complete IR sensor architecture also works in daylight. It includes an ambient light sensor capable of sensing light levels up to 128 kilolux. In addition, the advanced architecture of the Si114x family enables proximity-sensing measurements in 25μs, reducing the turn-on time of extremely power-hungry infrared LEDs, resulting in the industry's lowest system power consumption—20 times lower than other solutions .

The Si114x series includes an optional maximum of three infrared LED lamp drivers. Developers are free to implement one-dimensional HI systems that detect distances greater than 50cm or multidimensional systems with gesture sensing capability up to 15cm. The Si1142 and Si1143 devices have two and three IR LED drivers, respectively, enabling advanced motion and gesture sensing. With two integrated LED drivers, the Si1142 supports Z-axis and X-axis motion sensing for non-contact slide bar interfaces. The Si1143 supports three LED drivers, enabling innovative three-dimensional motion sensing in multidimensional non-contact control.

Coupled with the intelligent controls provided by Silicon Labs capacitive touch-sensing microcontrollers such as the F700, F800, or F99x MCUs, the Si114x sensors can be used for a variety of motion and gesture detection, as well as target object range calibration applications. The sensing mode of the Si114x device provides useful information to the MCU to determine the type of backlight, such as daylight, fluorescent light, or incandescent light. This information is useful in many applications to improve IR proximity sensing, optimize infrared sensing power consumption, enhance the backlighting of display devices, and control other devices within the system.

"The new Si114x family is the most advanced single-chip proximity sensing solution that offers unsurpassed sensitivity, sensing distance and power efficiency in a very small package," said Mark Thompson, vice president and general manager of embedded mixed-signal product lines at Silicon Labs. As the only semiconductor supplier that can provide both proximity sensors and touch-sensing MCUs, we offer developers a single-source solution that simplifies the next generation of human-machine interface design."

QuickSenseStudio and development board support

Like all other QuickSense product members, QuickSense Studio also supports the Si114x family of products. QuickSenseStudio is an intuitive, easy-to-use software design environment that enables developers to write, debug, and analyze proximity, ambient light, and capacitive touch-sensing applications. QuickSenseStudio simplifies the configuration of infrared proximity and ambient light sensors through an API library. The graphical runtime environment provides the ability to generate C language code for proximity and motion detection, gesture detection, and background light recognition.

Complete evaluation and development kits, including the Si1142 based contactless slider evaluation board IRSLIDER2EK and the Si1140DK development kit for Si11433-LED evaluation,

SiliconLabs provides an online light sensor power consumption assessment tool that helps developers evaluate power consumption in proximity and ambient light sensing applications.

Concrete Admixtures

Concrete admixtures is a material refers to the mixing concrete mixing before or during the process of mixing with to improve the performance of concrete .Concrete admixture content is generally not more than 5% of the mass of cement.The quality of concrete admixture products must conform to the national standard "concrete admixture"
