The PMA2102 UVB sensor is designed to operate in outdoor environment. A built-in temperature sensor and compensation algorithm correct for the temperature coefficient of the UV sensor.

A Teflon diffuser assures an angular response close to a cosine function for incident angles up to 50 making it suitable for measurements of diffuse radiation (sky radiation), often the major component of solar UV.
