5. UV Sensor Optical Filter
An optical UV transmission filter is recommended with the usage of ML8511. The material recommended isACRYLITE #000 (1.0mm thickness) with sandblast #220, if opaque filter is desired. The distance from ML8511
to filter is D1. D1 should be ~1.0mm. The aperture size of the filter is D2. D2 should be ~3.0mm.

6. Output Voltage – UV Characteristics
The below chart shows the linear relationship between the sensor’s output voltage and UV
intensity (mW/cm2) when Vdd = 3.0V. The sensor output is stable across the operating
temperature range.
