TheVCNL4035X01-GES-SB is a sensor evaluation board designed by Vishay Intertechnology with features such as proximity detection, on-board ambient light sensing, and a built-in IR LED. The evaluation board was created to help engineers develop hardware and software solutions for a range of applications from medical diagnostics to handheld gaming. This article will provide an overview of the evaluation board’s application field and working principle.

Appliation Field

TheVCNL4035X01-GES-SB evaluation board is capable of detecting proximity, ambient light, and temperature sensors. Its use in medical diagnostics is prominent in detecting distance between a medical instrument and body tissue. This is especially useful for sending light into the tissue for diagnosis and for measuring low power signals such as Autofluorescence and Raman scattering, both of which are used in medical imaging. The sensing range of the VCNL4035X01-GES-SB can reach from 1 cm to 30 cm, which allows for greater application range in medical diagnostics.

The VCNL4035X01-GES-SB is also useful in other applications such as handheld gaming, AR/VR systems, facial recognition, and 3D scanning applications. The board has the advantage of being able to sense both near and far distances, and the sensing range can be tailored to various uses. For instance, its proximity sensing capability can be used in facial recognition systems to detect changes in a person\'s face. This allows for accurate authentication, which is necessary for many smart devices and gaming systems. Additionally, the evaluation board’s ambient light sensing feature can accurately measure the lighting conditions in a room, which can be used in 3D scanning applications to capture a 3D image of an object with greater accuracy.

Working principle

The VCNL4035X01-GES-SB evaluation board is equipped with both an ambient light sensor and a proximity sensor. The ambient light sensor uses two separate photodiodes, one for visible light and one for infrared light, to measure the amount of light that enters into the board. These measurements are then sent to a signal processor, which then outputs the ambient light data to a microcontroller for further processing.

The proximity sensor is equipped with an infrared LED and a photodiode, which measure the amount of infrared light that is reflected back from an object. This reflection is then sent to the signal processor where it is compared to a reference level, and if the signal exceeds the reference it indicates an object is present. This proximity data is then sent to the microcontroller for further processing.

The VCNL4035X01-GES-SB evaluation board also includes a temperature sensor. This sensor uses a thermistor to measure the temperature of the board, which is then sent to the signal processor and sent to the microcontroller where it can be further processed. This feature allows for more accurate temperature readings, which can be useful for many applications such as medical diagnosis and 3D printing.

Conclusion

In conclusion, the VCNL4035X01-GES-SB evaluation board is capable of detecting both ambient light and proximity sensors, as well as a temperature sensor. This makes it suitable for use in a variety of applications including medical diagnostics, handheld gaming, facial recognition, and 3D scanning. By combining both the infrared LED and the photodiode, the board is able to accurately detect distances and light levels. Additionally, the on-board temperature sensor enables for accurate temperature readings in various conditions.
