ML8511 - SparkFun Electronics

UV Sensor with Voltage Output GENERAL DISCRIPTION . The ML8511 is a UV sensor, which is suitable for acquiring UV intensity indoors or outdoors. The ML8511 is equipped with an internal amplifier, which converts photo-current to voltage depending on the UV intensity. This unique feature offers an easy interface to external circuits such as ADC.

Safety Tips for Using UV Lamps - Berkeley Lab

The most hazardous UV radiation emitted by the UV lamps is that with wavelengths between 240 and 315 nm. In this range the threshold limit value (TLV) is less than 10 millijoules per square centimeter, and the most restrictive TLV is the UV-C at 270 nm, which is set at 3 millijoules per square centimeter.
