The SMOD711KITV1 evaluation board is a System-in-Package (SiP) based on the 711 sensing technology, which is a miniature capacitive MEMS (Micro-electro-mechanical Systems) proximity sensor designed for sensing air gap distances. The device is used to measure the clear air gap in situations when the direct physical measurement is not possible or cost-prohibitive or when direct physical sensing is preferred over mechanical proximity switches. The board is highly configurable, making it suitable for a wide range of applications in industries such as automotive, manufacturing, transportation, and medical.

This platform’s design aids a wide range of operational scenarios and configurations. Some examples include complete range coverage for measurement from Ø0.5 to Ø5mm to enable point-to-point air gap sensing right up through to automotive applications for active gap measurements with higher accumulation rates. This can be further customized to offer a broad selection of output rates, distances, material sensing and optimized analog circuit design. This board also supports statistical data, offering multiple duration and non-volatile storage of min/max data in the last x minutes, x hours, x days or x weeks.

As for the working principle, the SMOD711KITV1 is based on the principle of capacitive sensing. This works by charging up the physical medium to be sensed and then measuring the electrostatic force, that is proportional to the distance at a given frequency. It is worth mentioning that the capacitive waves propagate out in a well-controllable way with virtually no masking. The output of the sensor is typically a 0 to 5V signal, which can be scaled for distance.

The device offers a high level of accuracy. It is able to resolve small changes in air gap with a resolution down to 0.1micron. This allows users to detect small movements in air gap over time, such as those experienced in certain applications like automotive obstacle detection. The device also supports a large range of sensing materials which makes it suitable for use in a variety of applications.

Due to the versatile design and capabilities, SMOD711KITV1 can be used in a variety of applications in the automotive, manufacturing, transportation, and medical industries. In the automotive sector, the device can be used in parking assistance devices, obstacle detection, and active gap measurements. In the manufacturing industry, the device is particularly suited for use in the robotic and process automation applications. In the transportation industry, the board can be used in proximity sensors in automated docking and sorting systems. Lastly, the device can be used for air gap measurements in medical applications such as endoscopic surgery.

Overall, the SMOD711KITV1 evaluation board is a powerful and versatile tool for air gap measurement. With its robust design and many features, it is an ideal platform for various applications in a variety of industries. It offers accurate distance sensing capabilities with high levels of resolution and is suitable for use in both short and long range applications.
