Integrated Device Technology Inc (IDT) has introduced a light sensor that accurately detects levels of the UVA and UVB light spectrum, offering new health and wellness capabilities for wearables and other mobile technology.

Developed by engineers at recently acquired Zentrum Mikroelektronik Dresden AG (ZMDI), the two-channel ZOPT2202 sensor has ultra-sensitive photodiodes which, when coupled with the sensor’s patented infrared light suppression, deliver a high-performance UV solution.

In addition to health and wellness applications, the sensor enables ‘contextual awareness’ in applications.

“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,” said Uwe Guenther, product line director, Mobile Sensing, at IDT. “The ZOPT2202 sensor accurately senses 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.”

The global market for mobile sensing solutions is expected to see strong growth with as many as 1.5 billion units in use expected by 2018. IDT’s next-generation UV sensor is the latest product in the company’s portfolio of leading environmental sensing solutions for the mobile industry.

The ZOPT2202 sensor is available in a compact ODFN (2.0x2.2x0.7mm) package.
