IDT optical sensors portfolio consists of UVA and UVB light sensors, ambient light sensors, RGB color sensors, and proximity sensors. The ambient light sensor ICs (ALS) and proximity sensor ICs enable sophisticated display control in mobile devices. The RGB sensor ICs improve camera flash and picture quality, while the UV sensor ICs provide accurate information about UVA and UVB exposure.

Measuring UVA and UVB Exposure for Improved Wellness

The risks associated with UV rays, whether getting too much or too little, are well-documented. Overexposure can lead to skin cancer, and underexposure can result in seasonal affect disorder (SAD) or low levels of Vitamin D. IDT’s UV sensor ICs accurately sense the UVA and UVB light spectrum, offering consumers a better understanding of their environment so they can monitor and avoid risks associated with UV exposure. In addition to health and wellness applications, the UV sensor enables "contextual awareness" in applications.

About Ultraviolet (UV) Sensors

Ultraviolet radiation is defined in broad terms as that with a wavelength of 10–400 nanometers. However, the most common UV ranges are UVA (315 to 400 nm) and UVB (280 to 315 nm). UV sensors enable sensing of these common UV ranges and are used to detect the intensity of UV radiation. Given the health risks associated with overexposure to ultraviolet radiation - both UVA and UVB - UV sensors can find a variety of uses for consumer and safety applications intended to monitor UV exposure.
