UVA and UVB light sensor monitors environmental health risks

Able to detect levels of the UVA and UVB light spectrum, the two-channel ZOPT2202 sensor from IDT, has sensitive photodiodes which, when coupled with the sensor’s patented infrared light suppression, deliver UV levels and also a contextual awareness in health and wellness applications in smartphones and wearable devices.

By sensing the UVA and UVB light spectrum, consumers can gain a better understanding of their environment so they can monitor and avoid risks associated with UV exposure, whether over-exposures, risking skin cancer, or under-exposure, which can result in SAD (seasonal affected disorder).
Detectable UV index is from 1 to 11 and operating temperature range is -40 to 90°C

The sensor is available in a compact ODFN (2.0 x 2.2 x 0.7mm) package. According to the company, the package is optimised for stray light suppression.
The sensor is available in production quantities now, with evaluation boards also available
